Extreme modified Black Jack 26 EP ...

[hex-dj]

Hello! I have a BJ 26 EP with an AMMO 2300Kv, OSE straight coupler like in my SV 27, hallowed the motor mount to make it lighter, servo is feather weight with carbonite gears, original reinforced strut, sharpened Octura x637 2 blades prop. and fins , .150 original flex cable ,(I changed it in my SV for an OSE cable too), stock ESC with a Novak 2700 mf power capacitor, 14 cells, 2000 Mah , 4/5 sub-c cells, DSM Radios in both of my boats, Too fast... GPS ed 64 MPH. Thats with the slightly mod stock ESC. Temps were slightly warm... I ve got pics too ,but dont know how to post them...

[hex-dj]

Out of the hole...

[hex-dj]

At home after a long race...

[hex-dj]

I learned how to post pics my way though ,lol!

[kburrows]

video proof, always makes better than a picture. Awsome pic though

[hex-dj]

Dont worry my videos are comming soon...

[hex-dj]

I mean rain x does the opposite ,makes boats more loose.

[Mich. Maniac]

64mph or 64 km/h? I really hate to say it but I will, Nope, Just dont believe it. With NiMH cells and stock esc and motor? I wont say its impossible but not likely. And no heat? wow, How much do you want for it???? must guaruntee it does at least 61 outta the box! Nice pic as Burrows noted though.

Edit: I see now you are running ammo motor 2300/kv.

[hex-dj]

Hahahha! Mich. Maniac sorry mines not for sale unless I change my mind,but nahhh... Thing is I want all hull types of boats. I have my SV 27 "Vee", Blackjack 26 EP "Cat" , Soon the Miss Elam brushless "Hydro" and eventualy a "Rigger". The NiMH cells are from Electrifly and they come with a 14 AWG cable with ultra deans. I had to modify the batteries as well by changing the cable gauges to 12 AWG. I have a Pro Stock R/C car which I have taken to 107.37 MPH YES MILES PER HOUR with a Novak 5.5R setup and an Evader with a super hard transmission in 32 pitch with special tranny from Duratraxx and Traxxas ,using paddle tires ,special lightweight high torque servo hollowed some parts, added wheelie bars and read carefuly my Evader features a NOVAK 550 5.5 PRO brushless motor a GTB ESC running on eight special NiCD cells that weight as much as LiPos from Sanyo the famous SANYO 1300 Mah green cells.Im serious about the BJ 26 doing 64 MPH. I will run it on Sunday again to see if I come up with better pics, cause I am still to buy a video cam to post videos sorry soon i will get a video cam.

[hex-dj]

Ohh and not to forget I also want a real R/C drag boat ,but I was looking at them and the hulls from ABS seem pretty weak.

[hex-dj]

In my Evader I use Big rear only Paddle tires . In my R/C Pro-stock 107.37 MPH car I use rear foams at 3.75 inches tall and heavy bite. The ESCs I use in my other R/Cs are Novaks GTBs well you guessed it modified by me. I ve been able to add 10 cells to those and they can only handle 6 supposedly.

[hex-dj]

Sometimes companies do not tell you a lot of things I wonder why?

[blastoff]

What are you doing to the ECS ??? moffets ??? cooling ???

[hex-dj]

Iam working on their cooling a lot without sacrificing current flow,but its about knowing what to do and where to do it. Example soldering in the right spots of the ESC... and going against some factory recomendations. I have never burned a Novak ESC .Even when the factory recomends using six or 14 cells on them. I use many tricks that a lot of people dont know. Also experience is key too.

[blastoff]

ESC... and going agains some factory recomendations

[hex-dj]

About my Black Jack 26 EP... Today I made one final mod to the hull and hatch. I made it a convertible cat and I removed and repositioned some of the stickers it comes with to make it even lighter. Doesnt look bad. Seems like a convertible cat with two pilots ,after Sunday I will post new pics of it running and a close up pic. I am working with my digital cam ,because today I noticed that it can record short video clips.

[hex-dj]

Also on my Novak ESCs I never used the factory cooling fan. I use the small Radio Shack brushless cooling fans. I consider the factory ones weak and not fast enough to cool...!!!

[hex-dj]

And you cannot connect a fan to the ESC. It steals a lot of current from it.

[hex-dj]

I remember when I ran my fan cooled boats... Everything was different from a water cooled.

[hex-dj]

Hello blastoff. I think I gave the right advice to you on the ESCs. About my BJ 26...I just finished scuffing the bottom and sharppening the blades even more.

[blastoff]

Yep It sure looks fast LOL

[hex-dj]

Hello everyone here are the new pics of my BJ 26 EP in action. Sorry no videos yet as I was having some problems with my cam and the wind.

[hex-dj]

Yep It sure looks fast LOL
Take a look at my new pics now BLASTOFF!

[ozboater]

how about a gps shot......

[RCprince]

lol

[blastoff]

Here are a few pictures of my rescue boat, I have made pretty much the same mods (brushed) and it must do just under 39

[Jeepers]

64mph or 64 km/h? I really hate to say it but I will, Nope, Just dont believe it. With NiMH cells and stock esc and motor? I wont say its impossible but not likely. And no heat? wow!



what he said:iagree: even with the ammo............

[hex-dj]

Jeepers, did you look at what I am using? I have yet to come with a GPS shot ,because I wrote about GPS numbers at first here,but it was because a friend of mine had the gun .I dont have one myself and by using the tips and info estimate chart on this site I am supposed to do 60 MPH if you use the chart from OSE. Motor 2300 kv, cells 14 NiMH 2000 Mah and read well (4/5th)<---of sub-c cells, not as heavy as all other NiMH sub-c cells out there in the market.Iam using the lightest on a budget NiMH Sub-C cells on the market right now modified by me from 14 AWG to 12 AWG cable,not using LiPO yet.Notice the batteries were tightened using Home Depot stainless steel tip tie wraps which cost around $30.00 a package.Feather weight servo with Karbonite gears, hollowed and lightened motor mount,Aquacraft cooling jacket.Original ESC with a Novak 2700 mf Power capacitor soldered in the right place. Prop. is an Octura x 637 sharpened and polished by me,OSE straight coupler, notice the turn fins are shorter than normal and they were sharpened and cut by me,scuffed bottom.Removed and repositioned some stickers then added a small new sticker about hurst shifters, enhanced water holes for cooling, reinforced strut with better screws and hobby glue. Removed the pilot s cockpit top in the hatch and I am using a DSM transmiter with water proofed reciever. Shortened and angled the antena to the rear.If you want you can do the math on this sites tips and info boat MPH/speed estimate chart. Oh and about slippage since there is none for a catamaran , I wrote 22.5 % slippage ,because a cat is between a mono 25% and a Hydro 20% prop. slippage .Wanna race? I am saying my boat has to be seen to be believed when running, it has a lot of torque too...Also notice that the stock ESC can handle 18.0 plus volts and the motor 18.0 plus volts too .So I am not maxing them out yet!Racing on a budget is a reality with OSE. Steven s line is very true...OSE where racing on a budget is a reality...THX!

[hex-dj]

RC Prince why you laughed out loud? Is my setup funny? Please read about what I wrote to Jeepers.

[spinner]

So you didn't have a gps in your boat, like your first post said?

[RCprince]

Wait your telling us that you did 64 mph because of the Speed Estimate by Use of Voltage & Constant "Kv" chart here on OSE http://www.offshoreelectrics.com/conversion.htm...
I don't think so...Even with that motor running at 89 percent efficient( thats another lie by great planes, no way those ammo's are that efficient) spinning a 637 and 14 nimhs you'd get 59mph at 22.5 (your input) prop slippage not with those half dead nimhs...:sorry: :help: :sleep:

[hex-dj]

Spinner I used a gps gun not the thing you put inside the boats to get speed.

[hex-dj]

RC prince i wrote on efficiency 89%.If its a lie then we can all sue greatplanes for false promotion adds right?

[RCprince]

No, manufactures can write what they want(especially those selling china made products)...But there is no way that motor puts out 1110 watts continuous and 1850 surge that 1.4 horse power and 2.4 surge horse power, no way they are more like 300 to about 400 watts max.... and as for efficiency may 80...where as the Feigao's are 80 percent efficient and their magnet have more than twice the power, I've tested them as a matter of Fact I replaced my Ammo 2600 with a L size feigao magnet( rotor)

[RCprince]

Where are you located, If I may ask

[hex-dj]

RC Prince I am in the Caribbean LOL...

[hex-dj]

Rc Prince you have a very nice cat pic. Is that your boat on the avatar picture?

[blastoff]

Aruba ???

WOW! RC Prince ...nice,nice,nice ..Any pics or videos of it in action ...how fast can it go? what setup are you using?

[RCprince]

There are some others but I have to look for them

[hex-dj]

Ok no problem..awesome pics.How fast does it go if I may ask?

[RCprince]

I got 51 plus out of it oneday.....then i got preoccupied with my outboard SV, now I'm preoccupied with my BJ outBoard

[hex-dj]

Cool!

[RCprince]

Outboard...I'm gonna run it with 2 - 4s lipos in series

[hex-dj]

How fast is the outboard? Nice job.

[RCprince]

I was just doing test runs with it....with the BJ motor I got 31 out of it....when I'm done with it I'm trying for the high fifties.

[Jeepers]

[QUOTE=hex-dj;42121]Wanna race? QUOTE]

HOW MANY LAPS HEAD START DO YOU NEED????????

I sure hope your repositioned decals that help increase speed:
are glued on cause my rooster tail is goona peel them off.


OH and I watch BJ26s race all the time so I know what they are capable of.

Iam done here.

[hex-dj]

Peace Jeepers!Im only talking about a friendly race...no offense...Im sorry but that BS sign, you re gonna have to remove it from your post though ,because it seems you did not understand very well about what I wrote about...My repositioned ,eliminated and newly added little decals decrease weight in the boat,helping it run faster. Stickers add weight to any type of R/C. It is not BS OK. By the way what setup are you running,and what is your boat a BJ 26?

[z400]

hex...


i have to ask.
How long exactly have you been into this hobby?

[hex-dj]

I started in 2002 z400 as a real hobbyist ,but I began running rcs back in the 1980s...if anyone rembers the Nikko Lobos,I ,II and III. I got pissed at all the drag race guys always trying to make me feel ridiculous ...so I decided to learn all the tricks I could until today with research and personal practice experience.

[RCprince]

lol, this is comedy central.

[Jeepers]

pick one!


just kidding not all those are mine! 4 of these are though.... well one is my dads. I will NEVER own a BJ26 or SV27 dont like them.

sorry hex didnt mean to be rude forgot to add all the smileys.

but I did understand you sticker part and its still BS. that tiny amount of weight is nothing compared to the amount of drag that hull has. 64 MPH no way!! 46mph possible.

the only reason people are giving you a hard time, is MOST of the guys here KNOW how much power it takes to break the 60 mph the little ammo on nimh's in that hull just dont cut it.

Heck one of the fastest guys in the US (on this forum) has a superior hull,motor, batteries, and only got 61mph VERIFIED on a GPS UNIT . (He has gone more than 80mph using an outrigger hydroplane and timing lights (like they do at FULL SCALE drag races) these are the MOST ACCURATE way of measuring speed)

[hex-dj]

Well Jeepers ... I remember I wrote, I am using an Ammo 2300 which is lighter than all the other brushless motors. I use feather weight servos with Karbonite gears, hollowed the aluminums, lighter than normal 14 4/5th NiMH batteries 2000 Mah ,run time is around 20 minutes. I am using an OSE straight coupler and the aquacraft jacket. Shortened and sharpened all fins and prop. I am still using the stock ESC which I have improved by adding the Novak 2700 mf Power cap.Scuffed the bottom. DSM radio.Please take a look at my Black Jack 26 EP pics! Nice collection of boats WOW!

you maybe using the lighter motor but your using ANCHORS for batteries go lipoly you will see what we mean...

[RCprince]

Dud let me interject here....Lol am I in the twilight zone or what, But dude there is no way, NO WAY in heaven or hell (If I'm not being polite excuse me) that your gonna get 64 mph out of that boat plus 20 minutes run time with those half dead nimhs...you have an extremely vivid imagination...Stop it, Stop it, Stop it please... plus you have on your turn fins...you might as well put on parachutes.

:iagree: what he said

[hex-dj]

Prince I have Tested it many times. What I m saying about run time is true. The batteries will completely die out after 15-20 minutes of running and no heat at all. These bats. are 2000 Mah 4/5th of sub-cs from electrifly had you ever mod them or try them out in any of your boats.

[RCprince]

Dude I'm flying to the Virgin Islands on the 3rd Via San Juan...don't make me do a fly by

[hex-dj]

My bats. are NiMH too.

[hex-dj]

Sure come anytime or Ill get to Kissimmee in no time LOL!

[blastoff]

Did you do GPS before and after the sticker modification ??? If so how much faster was the sticker modification ???
Get ready for some sticker shock guys !!! LOL
Also:
How much faster after removing the drivers ???
How much faster after bending the antenna ???

[hex-dj]

Do you have a BJ 26? You can try it out yourself Blastoff.LOL

[hex-dj]

Blastoff I do all mods together not one by one.LOL,LOL,LOL...
And Im done here...Night...

[blastoff]

My last project went Mach 3.1 until it glitched.

[RCprince]

Dude you need part in the Dave Chappelle show...your too funny...stop trying to give us a 6 for a 9...Stickers makes a difference in speed....why not take off the gel coat, the smoothness might cause a vacuum effect where the hull sticks to the water.

[hex-dj]

Prince are you chicken? LOL You re funnier yet!

[hex-dj]

Blastoff you may never see the GPS for Mach 3.1 since it will melt and be destroyed before even measuring a GPS speed.... Goshh! Funny,funny,funny....LOL,LOL,LOL...

[RCprince]

One thing I did notice is that after I posted that 58.7 mph black jack, you removed your drivers canopy like he did...lol I guess your gained 3.2 mph...lol

Pointless and retarded? Not in my book !!

They are absolutly hillarious. :laugh: This is one of the best reads I have had on forums in a while, and that includes the cat and greased string bit. ( go have look for that one )

[Jeff Wohlt]

HEX...so you did all that to save a few oz or so but you still have a darn radio box in it? That has to go if you really want to save weight.

Nobody has run a BJ 60+...yet. 50's on a good day without blowing off. The hull was never designed for much over 40....but some get a lucky run out of them.

How they look and what a GPS says is a big difference. Even a GPS is not fool proof. A radar gun is the best but can still be off if the person does not know how to use it right.

Good thread...for the most part...unit the bench racing began. Want to get in to the real speed get a good hull and some NEU motors and lipos. You can then burn the water up....and your wallet. The ammo motors are pretty darn good for the money.

[hex-dj]

About the radio box Jeff... Can you advice me on where to place the electronics? I need advice on that one. Didnt think of it until you wrote it.Oh Jeff I saw your store do you carry a good strut for my BJ 26 EP...if so advice me on which one to buy from your store...THX!Seems TLR got away with my money too.

[Jeff Wohlt]

I do not have a BJ 26 but You would mount the servo in a bracket and then most just leave the ESC out or mount it on top of the motor with hook and loop tape. Your boat needs to run dry and mine do but that takes a little work as well to make sure the driveline does not leak, etc....basically all fasteners sealed, etc.

With power today not sure you really need to dump the box. I just saw where you went to great lengths to save weight and that is usally the first thing to go.

As far as struts...I have some but may end up designing a new hardware set for that hull a or to fit most any cat.and they include a bracket but you either have to mount your rudder in line...which I like for cats, or drill new holes for a rudder bracket.

Steve was working on some to fit that but not sure he has any yet. My cats all run in-line rudders because I do not race them and like them to turn both directions well and keeps resistance from the water balanced to the center of the boat.

[hex-dj]

Ok Jeff, I ll remove the box then...Which is the best way to seal a drive line completely?

[Jeff Wohlt]

I use a shrink wrap ca'd to the stuffing tube then put the shaft in and shrink it on the shaft....even two layers is good. Some use silicone tubing and slide it on the stuffing tube and then just leave enough to touch the flax shaft. I mainly run wire drive and use the shrink and my boats run dry. Make sure all other holes and hardware enter the hull have been sealed.

Look at the Etwones on the site here...he has no box in his. (Fullers Hardware thread) Most of us run our boats this way. Clean and also gives you more room to adjust cells, etc. You can also slide a small piece of sponge under the cable close to the motor to soak any water that may drip.

[hex-dj]

Thanks Jeff!

[hex-dj]

Ok Jeff I just removed the radio boxes in both my BJ 26 EP and my SV 27 EP... Now that I ve learned to take videos with my digital cam ,I will take some vids. on Sunday and hoping for a big increase in speed...Thanks man!

[Jeff Wohlt]

Hex....don't expect that much diff. Not sure what it weighs. But not that much. Your boat will run better by trimming it so it handles and gets top end. You do this with strut depth, angle and CG.

cat and greased string ??? Please explain !!!

[Jeff Wohlt]

Some of this thread is obviously BS but any real FE racer that has any clue of FE rc boats do not run radio boxes. Of course...we also do not run box art boats either, we build ours for top performance from the ground up.

Most seasoned FE folks know that the box art hull designs and capabilities are pretty crappy. Of course, you get what you pay for. They are decnt for people that really do not know how to build and want an almost fast boat they can take out of the box and throw cells in and go.

[blastoff]

Or embellish

[Jeff Wohlt]

True...and I hope I did not insult anyone by my comments above. It was only meant to say to not expect a lot from their boats but they ARE doing some neat things and getting some great speeds.

Many times it is more impressive to see people get box art boats flying and more of a challenge than getting good hulls to run well. So I am now interested in what can be done with these smaller hulls.

[blastoff]

This is to funny to pass up

Ok Im funny ,but you know what? I ve just instaled ,sharpened and mod the TLR system for my BJ 26 ep which arrieved today after a darn month waiting and they wrote my address so wrong... LOL...Look at my new strut pics.Also notice the pin added to secure the hatch and to keep it from opening in case of a high speed flip.Notice the replaced ,repositioned and newly added stickers ,plus the new setup pics!THX!

[blastoff]

Pics !!!

[hex-dj]

Here is another pic of my BJ 26 EP!

[H&MWill]

Dude are you EVER gonna post the video or not?

[Tunda]

that set up will never go 64mph like he said...... may be if he ads 2 rockets lol........

[hex-dj]

Yes I will,just dont have a rescue boat anymore ,I must get another one first!

[RCprince]

I'm thinking he's transposing the numbers, he means 46 mph not 64 mph...and another thing remove that battery tray the CG is to high.

[hex-dj]

Ok R/C Prince I ll do that mod with the batteries. I think I ll have to change the prop. too. I m planning to get an Octura x640 or a different one. Slowly ,but surely i m doing all the mods I can. THX!

[Mich. Maniac]

I would think removing the canopies over the drivers would have taken away wind resistance as much as the weight you removed. Cut the drivers completely out and seal the holes with something for a flat top. Then maybe you could add a wing for downforce cause at those speeds you will need it. Nice hardware though. Glad someone got something from TLR that wasnt a hassle

[hex-dj]

Ok, I ve just removed the battery wooden trays. I have a lower CG now.

[hex-dj]

Ok here is a pic of the OSE chart with 60 MPH. All charts point to the same results after I input the info on the gear that Im using... Why cant I trust the OSE charts, the GPS or radar guns? Should I just look at a full sized cars speed when passing by and think of my boat running and hey I ve done this also and it seems the charts ,GPS or Radar guns are accurate enough to make me think my boat is doing 60+ MPH... None of my boats motors or ESCs are being maxed out yet. I can imagine having 16 or 18 cells or perhaps 6S Lipos in both my SV 27 and BJ 26 EP. LOL

[RCprince]

"These formulas are for a estimate only. If you like to play with numbers these tools can be a major help in starting a new boat building project.

Please keep in mind you can plug any number you like into the fields. It doesn't mean that it will work! You have to have a basic understanding of the limits of your parts."

That chart is just bases on theoretical factors...it doesn't mean that those parameters come to fruition..First off you don't know exactly if those cells are putting out 14.2 volts under load, second you don't know what efficiency that motor is working at...Electrifly say "UP TO" and third you don't know the actual prop slippage. It clearly says :""These formulas are for a estimate only." GIGO: Garbage In Garbage Out.

Hex, why worry with sticker weight if youre just gonna go and put electrical tape all over everything inside your boat??? Doesnt that cancel out????

[z400]

the electrical tape adds power.

[chirotray]

Oh, because it holds the voltage inside the wires!! Sweet. All this thing needs now is a flux capacitor and its on like donkey kong!

[frdvschvy]

Dude, your center of gravity has got to be soooo far forward with your electronics and battery placement. With that kind of center of gravity the boat has to be running VERY wet! Not sure how you could see over 40 mph with this setup.

:confused2: :confused2: :confused2: :confused2: :zip-up:

[chirotray]

Stickers balance it PERFECTLY

[z400]

he's got so much power.


everything moves to the back of the boat. when he slows down, everything magically moves back forward.
its sweet.

he'll explain.
haha

[frdvschvy]

Stickers balance it PERFECTLY

Ahhh... so true. I forgot about this very important factor. Mine must not run over 50mph because the sticker placement is all wrong.

[chirotray]

Its ok, just move the stickers around, smooooooth the bottom of your hull then coat the whole thing in electrical tape and rain-x and it will be all good in the hood!! welcome to the 60mph club with these mods.

[hex-dj]

Chiro where is your boat? Can I see it or is it just an imaginary boat that you have? Show me your boat and stop criticizing.

[hex-dj]

Frdvschvy Thanks... I ll just move everything to the rear and test next Sunday both boats... !!!

[chirotray]

My boat is absolutely nothing special compared to these other guys, but then again im not making speed claims either. My only claim is that this boat out of the box with 5000 30c lipos is suprisingly fast.

[chirotray]

And for the imaginary part, how about that gps? Wow i just reverted to the fourth grade. Oh well.

[hex-dj]

Where is your boat?

[hex-dj]

Hey Chiro ,come on...Show everybody some pics and videos please!

[z400]

Wheres the video?


why should he show pictures and videos of his boat in someone else's thread?
the maker of this thread cant even post a video of his own crap.

[hex-dj]

Show everybody some pics and videos please!

[chirotray]

Working on a pic now. Give me a min to figure it out.

[chirotray]

Im having a problem with file size, so let me give you a mental image..........stock black jack. scuffed hull. 5000mah lipos. JR radio. Stickers in the original spots. Nowhere near 64 mph.

[hex-dj]

Resize your image to at least 35% when you edit it Chiro.

[chirotray]

Pics arent happening tonite. I cant seem to make it fit. Maybe soon, but i dont understand why you want to see mine when i told you what it was? Do you just want to see that I actually own one or what?

[chirotray]

Wheres the video?


why should he show pictures and videos of his boat in someone else's thread?
the maker of this thread cant even post a video of his own crap.
Thats a good point. Why didnt i think to say that!

[hex-dj]

I purposedly made these two threads one for my BJ 26 and another one for my SV 27 so I could get experience with forums and gather some helpfull info about my boats.I think these threads are like done by accident,but all the help and the crap some of you had written for example z400 writes helpless posts and replies sometimes ;is apreciated by me. As I have experience with drag racing in asphalt and on dirt I have gathered all that I know from cars and put some of it to practice with boats... Chiro has no boats to show ,because he can post his pics somewhere else and tell me about his invisible boat...By the way I ve just finished moving the electronics to the rear of my BJ 26 and I am ready for a Sunday video and some test runs....Peace and thanks to all.

[z400]

just wantin to see video man.


no need to start whine'n

[Tunda]

hex your nose is getting longer then this thread..............................

[Ub Hauled]

Come on guys, the mockery has gone far enough... let the kid "tickle"... don't shunt him down.
He may be under the impression that his boat is really going that fast... or maybe it is that fast. The point is, it doesn't matter,
if you think he's blowing smoke, just don't read the thread.
This is really not going anywhere...
Thank you.

[Ub Hauled]

Hex, take some time to search around and see some setups that the pro's are doing,
I am sure you can find several people that have posted here (or elsewhere) so you have an idea of how a clean setup should look like... it'll help you to have things organized inside a hull or at least you'll feel good when you look at it.

[Diegoboy]

Without neither belief nor doubt in Hex-dj and his claims, I want to get in on some of this. We've all seen his setup. Now take a look at mine. I'd like to ask what speeds should my setup be running at, based on the claims of Hex-dj.
Anybody...?

That's a Feigao 8XL on a CC Cuda 125.
HW is custom by Lonewolf.
Prop is stock (pictured) Also ran X642, X645 & M435/3
12 cell 3000Mah power (NiMh)

If Hex can run 64MPH on the Ammo, What should this 8XL put me at?

[RCprince]

Diego...I would say about 50 mph.....this is what 64 looks like, hardware is a Neu 1521 1.5(1860 kv), a Jeti spin 200, dual 5000 thunderpower 6s2p spinning a grim 45x68

[Jeff Wohlt]

The 8XL is 2084 KV and the ammo is 2300 KV. He is turning approx 4,000 more rpm than and 8XL with 14.4 v.

I'm with UB.... if you think you know better then why respond. Certainly has been a fun thread.

[Diegoboy]

You're correct Jeff. @ 14.4V, she was starved for power. She was begging for more voltage, and I don't have any more to give her. I have all these boats, and no batteries.

:iagree:

Ub Hauled, you are right, but this guy has to back up his pompous claims, that's what is irratating people here (along with his LOL's and stupid replys).

I too, am getting the humor in this. HOWEVER, if you (hex-dj) are feeling “picked on” you deserve it. As far as I know you are either a newbie (like me - but I'm not the one making these arrogant statements) or someone that has 50 years experience with RC boats (probably not, because you would know better).

Why do I feel this way? In the SV thread, in the discussion about scuffed hull bottoms I (respectfully) said:

My opinion…

Are you familiar with “window clings?” These are the paper thick, translucent, plastic decorations that are put on windows for holidays, birthdays etc. You get them slightly wet and place them on the window and they stick to the glass.

I believe that a smooth bottom makes the hull adhere to the water in the same fashion that a window cling sticks to the glass. Also, if you have ever tried to attach a suction cup to a rough surface you know that it does not stick well, if at all. Hence the reason for roughing up the bottom of a boat.
You responded with…

Add water to any papper and it will stick to anywhere rough or smooth surface.

&

Also about suction cups,they stick better if you add water because water serves as glue to anything you add it to.

Just to clarify, because it seems that you missed some very important points...
#1 I was not talking about paper, I was comparing the thickness of the plastic (as in PAPER thin). Plastic is more rigid and it needs the water to fill in the gaps on the surface.
#2 The water on a suction cup acts as a seal, to prevent the air from getting under the cup, and it won't even do that if the surface is rough enough. It is in no way shape or form, acting as glue. In fact, water is known as the universal solvent. Pure water will dissolve or break down nearly anything.

Also, the charts on the OSE site (Speed Estimate by Use of Voltage & Constant "Kv") the calculations do not take into account proper trimming of the boat, i.e. scuffing, rudder angle, prop angle, running wet, etc. Note that the title is a Speed ESTIMATE.

Now quit blowing smoke up our a$$es and show us some credible video. Put up or shut up. :flame42:

[eric-paul]

Well said!

[Jeff Wohlt]

I agree with Chop. This is more for fun than fact...I think he would make a good bench racer.

Chops facts on the bottom are exactly correct.

So bring out the video or admit you might be seeing high 30s and maybe 40mph :)

You would also have to be a darn good driver to keep that hull on the water at WFO more than a couple seconds at anything close to 50 mph.

When I started I thought I was goiong fast as well....until I GPSd it and said...no way...I was going twice that fast !! My 30 mph sure seemd like 50+ back then....now I know what 50-60+ looks like. Even vidoe does not give a good indication.

[Ub Hauled]

Guys, I know the comments he is making are quite "super"... all I am saying is, he's getting the best of you all... maybe even laughing at it. We don't need another sheisty (spell?) thread... maybe if one really feels that proof is necessary, just say; "put up the video or no more comments!". Let him be talking to the letters on the thread.
Jeff, well said, until one GPSd or "trapped" the boat, all the guesses are just guesses.

[hex-dj]

Nice setup Diegoboy.

[Diegoboy]

Thank you Hex!

[domwilson]

Hex, these guys are just having fun with you. This is a really good forum with alot of nice, knowledgeable people. I feel that you were just trying to get some suggestions on how to improve your setup. I also noticed that you took alot of advice and put it to good use. Your means of harvesting information may seem a little quirky, but the end results are a positive. That being said, keep on modding your boats. Some here will enjoy the entertainment and at the same time learn a little something.:doh:

[chirotray]

Ok Hex, let me respond to a couple of things, then ill make an official statement. 1. you told me to get more experience.....ok, well im sitting on 17 years of rc. For the last five years ive worked for hobby shops, currently i work part time for one of the largest private hobby shops in the world. 2. to answer your question on "chiro" , it comes from a greek word meaning basically to use your hands. I use it in my name because I am a chiropractic intern. 3. you keep mentioning my imaginary boat, if you will read through the thread, i never one time mentioned my boat until you asked about it, and then i made no claims whatsoever about it, and up front said that it was bone stock with lipos and a scuffed hull, yet you still demand pics. I tried to upload, but was unable to, so this weekend my friend is going to meet me with his supervee, and we will race and video tape it and put it on youtube for you.
Finally what I want to say to you is that there are a lot of really knowledgable people on here, I bet that if you add it up there are several hundred years of combined experience, and you make big claims, dont back it up, then argue with them on suggestions. That is the source of you being picked on. I will stop picking on you because honestly im starting to feel a little bad about it, thats not how I usually am. But I will say that I am going to post a video just because you asked me to. So now Im asking you to do the same thing before you make any more claims to big speeds.

[Jeepers]

Without neither belief nor doubt in Hex-dj and his claims, I want to get in on some of this. We've all seen his setup. Now take a look at mine. I'd like to ask what speeds should my setup be running at, based on the claims of Hex-dj.

hey diegoboy just wonderin if its gonna be as fast as dirtysouth Miss Vegas, remember that video? man that video cracked me up!

[Ub Hauled]

For all of you "Black Jackers", maybe this will be of interest:

http://www.aeromarinerc.com/runninggear.asp

scroll down to the middle of the page... there is an upgrade kit for the BJ 26.


ps: Sorry Steven V. if this is of conflict.

[Mich. Maniac]

awesome, thanks. I added that to favorites. I like fullers stuff but this looks a little more specific to the blackjack in mounting aspect.

[Diegoboy]

Jeepers. I found it!

The GPS was reset then closed into the hatch @ 00.0 Then after this short run, we opened the hatch to see this.

Here's the long awaited video of the 69.9 Mph Vegas...

I'm having difficulty with my converter program. Movie maker won't read MOV files, my camera records in MOV format. I have to convert to AVI, then I can edit, but the converter is busted. Anyone have the ability to convert MOV files to whatever??

Anyway, Here's the Video (http://www.diegoboy.com/media/vegas-69.9.wmv)<--

[hex-dj]

That video is too short.

[Jeff Wohlt]

And this was reset before the car ride to the lake :banana:

Damn fine speed there. COngrats. I believe a GPS.

[Diegoboy]

Ya. the GPS was powered off during the trip (all of about 1 mile). Powered on @ the pond, reset to zero, then placed in the hull & taped down. That super fast 10 second run showed 69.9MPH. Just goes to show that accuracy on GPS systems isn't perfect.

i have there hardwear and you have to re drill holes in the boat. and its just a pain i wish i bought fullers...:sleep: once you get it running good with some 3300 worn out packs i saw 33 mph. i need lipos!!!!!

[crazzy maxx]

if hex's boat hit 64 mph on nimh my testicles are the size of russia

[Jeepers]

That video is too short.


its supposed to be short, the boat never moved and the gps showed 69.9 mph!

[Jeepers]

HAHAHA! thats it!

[z400]

lmao i love this thread

[crazzy maxx]

lol
ill second that

[hex-dj]

Monday I am sending an MO to get my Radar gun. I trust them best. It is no wonder cops always use them on the road.

[boatpimp09]

how about a gps shot......

yer thats what was thinking:confused2:

[Apples1]

yeah whatever happend to those Ultra Ultra Modded BJ26 and SV27 doing ridiculas speeds @ mach 2 or warp 5 or whatever.....?

[Meniscus]

I have an Ultra, Ultra Modded BJ26 and it goes an estimated 37mph on Nimh. When I do the math for scale speed, adjust for weighted averages, and amend the original speed assessment, all of a sudden it's doing 38mph on Nimh. Then again, it could have been 36mph. LMAO!

I'll get it on GPS next time, only my phone only does 8 seconds of video at a time ;)

[Doby]

hex-dj had a bit of a meltdown in a thread over some shipping dis-agreements with Steve and has not been around much since then.

The mystery of the 60 Mph+ BlackJack remains just that,,,,,a mystery.

[Meniscus]

Shipping meltdown? Are you sure that was hex-dj? ;) LMAO!!! :roflol::rofl:
