Miss Geico Twin

[blackcat26]

Got a little work done on a fall project. Gutted her, cut the stuffing tube out, made some marine ply supports for the back of the transom and laid down some carbon/kevlar. Ran out of resin if you are wondering what is up with the different colored line on the tunnel area. Not sure about the powerplant just yet. Just a little something to keep me busy during the thundercat build.

[tiqueman]

Yeyhah! I knew it wouldnt be long.

[johnf]

Nice work. The ck looks really good!

[Make-a-Wake]

Yeyhah! I knew it wouldnt be long.

Yep.............. here we go...............:rockon2:

[blackcat26]

Thanks guys, just got the hull yesterday, so I am super pumped about it!

[Make-a-Wake]

How about a couple of Feigao 540 12L's on 4s............:buttrock:

Hmmmm... let me guess your droppin in those scorpion motors you picked up the other day:thumbup1:

Ohh yeah! :thumbup:

[LarrysDrifter]

This is gonna be sweet!I say stay away from 2 pole motors,such as Fegiaos.Just my opinion.:popcorn2:

[blackcat26]

Alot of motor speculation here! Ha I really am undecided as of yet. I have some "l" can turnigy's that made the blackjack do about 69mph on 4s. Also will have some Scorp's that would be quick on 6s. Not sure yet. You know me, I am hooked on massive rpm's!

[Make-a-Wake]

If you want 4 poles........Leopard makes a 4050 4Y.......2260kv that would make it fly on twins. Not to heavy or bulky, but plenty of juice. 4s would get them into the "massive" rpm zone you crave..............

[Darin Jordan]

Right on! I knew someone would do it!

I just ordered the parts yesterday to put Two Stiletto Outboards on the back of one! :D

What are the rpm's you like?

[blackcat26]

What are the rpm's you like?

Well I know I will catch some hell here but 40k minimum for me. May be stupid to some but it's the best way for me to go fast.

[RCKong]

Well, those scorpion outrunners you got will certainly do the trick - for sure... I think we have all seen Von Mudl's videos... In fact I just ordered 2 1400kv scorpions for my genesis build.
Monkey see monkey doo !!!

RCK

[blackcat26]

Lol no doubt. He's getting 83mph on the 1400kv flavor of these on 7s. Pretty impressive I think.

[timjz]

Right on! I knew someone would do it!

I just ordered the parts yesterday to put Two Stiletto Outboards on the back of one! :D

I just ordered 2 of those as well! Though I bet I paid more than you :glare:

[blackcat26]

Tim those motors I'm getting from you are going in my thundercat31 twin. Absolute perfect timing for you to post those babies. I feel like they may be pre-owned tho.......

[blackcat26]

Btw if I don't reply to everyone in this post it only means you are stupid. :w00t:
Just kidding. I am sometimes overwhelmed and forgetful so don't get your feelings hurt or anything like that.:sorry:

that hurts, I put a thoughtful, heartfelt message together and you ignore me...:eek:

So what is the status of this famous twin setup? I have been lurking on this, waiting and checking to see what you are gonna do. I have a buddy who has speed in his need - problem is, he doesn't wanna work on his boat.... hopefully he will sell it cheap to MMMEEEE.

How ya gonna mount those babies?

dang, you just missed my Castle motor sale, i let go a couple 9000 KV motors, you could have done twins on 8S..... you want rpfreakinms.. let her howl good man

9000kv's yeah, now your talkin.

Jesse my man. By babies you talking motors? Well, I have a few choices. One is an aluminum mount that follows the countours of the bottom and sides in each sponson (or the same in carbon fiber) Or I can jb weld in a aluminum one like I made for the blackjack twin thats basically a smaller brother to ose's stamped out one. Mounting the motors will be the easy part compared to coming up with some stingers for this thing. Very little room to mount those. Might go custom stinger non-adjustable and neutral then make up for it with COG. My bjtwin is dead level and thats where she purrs. Stayed up late last night and looks like she has got a bad case of carbonic fibrosis on the transom's now........

[Jesse J]

How about this strut (http://www.toughracing.com/zc126d/index.php?main_page=popup_image&pID=109) from Tough Racing? I used the bigger version on my 38" intruder - worked great. not cheap, but might be an option.

[blackcat26]

Will look into it Jesse, thanks. Looks like from the dimensions it might need to be cut down to fit.

[tiqueman]

Why not cut the bottom of the transom overhang out and re-build it? Make it like an upside down tub the the HOTR, Genesis etc. then you could use whatever stingers you want. I mean if your gunna do it...... might as well get crazy. It will give you something else to do. :tongue_smilie:

[tiqueman]

hopefully he will sell it cheap to MMMEEEE.



Then youd want to sell me the P-1.. Yeahhhhhh :lol:

[Jesse J]

...... hold your horses, I haven't even gotten to cuddle with her yet (wife is out of town - she wouldn't even know).

That would not be out of the question for me to do something crazy like that....

[Darin Jordan]

That would not be out of the question for me to do something crazy like that....

You guys are breaking my heart! Cut it all up??? :crying:


;)

[Rumdog]

Nooo dont cut it! Just use hydro style struts mounted right to the transom overhang.

[blackcat26]

Nooo dont cut it! Just use hydro style struts mounted right to the transom overhang.

Oh no, this must be killing Darin! Hey Ryan I didn't even think about that. One more option to consider. I am almost to the point of drilling a 3/8 hole and inserting a "fixed stinger" then jb weld the whizz out of it from the inside.....

[Rumdog]

Yep, it'll be gravy. You may have to reinforce from the inside though.

[blackcat26]

Just checked the hydro strut from a Elam and it's too tall.

[Rumdog]

The bracket?

[tiqueman]

You guys are breaking my heart! Cut it all up??? :crying:


;)

Yeah but when finished, how sweet would it be. Its by no means knocking your boat Darin. I cant wait to get one! BUT, if it makes stingers work, why not.

Say no so struts hanging off the transom. As more adjustment as they may be, they make a scale cat look like a toy. JMO of course. If its gunna be done, make it look right. :thumbup1:

[Rumdog]

Yeah, but cutting off the transom overhang will shorten the tunnel length. Therefore, it will blow off more easily.
Plus, that wouldn't look scale either.

[tiqueman]

No No No... Rummy, walk with me... Dont cut it off. Your cutting part of the bottom of the overhang out, then rebuilding it to make "tubs" Look at the bottom of the overhang. In the water, you would never know it was done. I havent looked at the bottom of the MG in person, but Im pretty sure it would work

[Rumdog]

It may work. Dont even show me that genesis. What a pain to make a twin outta that damn thing.

[tiqueman]

It may work. Dont even show me that genesis. What a pain to make a twin outta that damn thing.

Apparently you havent seen my new build thread...:spy:

EDIT: Yes you have... that problem will be going away

[Rumdog]

Yeah, I've seen it! That's gonna be a kick ass boat bro.

[tiqueman]

Yeah, I've seen it! That's gonna be a kick ass boat bro.

Lets hope.

I need one of these Geicos. Maybe 2.... one stock and one twin. I gotta keep up with BC26. We followed eachother on our first twin builds... then he kep on runnin... crap I gotta lotta work to do. Maybe I will just pick up a hull. BC, where did you get yours? From HH?

[blackcat26]

Got mine on the swap shop. I was gonna twin my first one right off the bat but I figured I would run and test a little first. Now I have a single and a twin! I am leaning real hard on a fixed stinger. Cheap and easy and sturdy. Only problem is there is no adjustment. Risky move....

[tiqueman]

I think youll be okay. At worst case scenario you have to break the tubes loose and re-epoxy them. Not the end of the world.

[blackcat26]

Good point. Does everyone agree that neutral or parallel with the sponson bottoms is the best all round position?

[Rumdog]

You may need some negative angle to keep it on the water. I ran about 3 degrees neg on my twin sprintcat.
It's hard to say, till you run it.

[Jesse J]

I say go neutral and use a tunnel flap to control the bow (where is the Dr. Evil pinky to the corner of the mouth icon?)

[blackcat26]

Would that be eeeeviiiilll? I think I will go neutral on em. I will finish turning them out tomorow at work and install this weekend if I have enough Jb weld. :w00t:

[Jesse J]

you can also use epoxy to set the stuffing tubes in - a little less permanent. Must be nice to be able to appropriate company resources according to the correct priority, eh? I say, if you can... you can!

[blackcat26]

Wont epoxy get gummy if heated too much tho? Yeah work has it's perks sometimes. A 4axis cnc vertical mill comes in handy at times.....

[Jesse J]

yes, but how would it get heated unless you used the woman's hair drier on it? the stuffing tubes shouldn't get even warm - unless you did something drastically wrong. that is why it is less permanent.

[tiqueman]

I always use epoxy on my stuffing tubes and have never had a problem.. Not the plunger tube walmart stuff, but the LHS stuff. 2 bottles, mix it w/ a stick.... Plus it looks nicer than a nasty grey blob. (JB weld)

[blackcat26]

Thanks guys I'm on it.

[blackcat26]

Got my stingers done today and poked a few holes in the back of her. Ran out of time tonight but will get em installed in the morning. Nothing fancy just basics.

[tiqueman]

Oh man.. those are nasty cool!

[HYDROJERRY]

O baby,, Get-R-Done:rockon2::banana:

[blackcat26]

OK got some more body work done yesterday on her and am debating on whether to go ahead and put the stingers in now or wait til after I prime and paint. Probably need to paint first but man I want to put those in bad!

[Rumdog]

Why all the tunnel work?

[blackcat26]

I sanded thru the glass in the upper right corner in the picture when stripping her down and decided to take a little of the dip out. Probably not really needed but wanted to true it up a little.

[blackcat26]

Got the stingers in and am waiting for the epoxy to dry. Like waiting for Christmas.....

[blackcat26]

Epoxy done and ready for water pickups.

[tiqueman]

Looks really good. When you want to make another set, let me know. You know.. just in case.

[johnf]

Lookin very nice!

[blackcat26]

Aight tique. Thanks John.
I was thinking about painting over the carbon fiber but that may be against the law. (in fe world)

[tiqueman]

How are you painting it... or did you tell us above and I forgot?

[blackcat26]

Just gonna rattle can the bottom with some epoxy white. keepin it simple.

[tiqueman]

Just gonna rattle can the bottom with some epoxy white. keepin it simple.

So deck and sides are staying factory?

[blackcat26]

Yeah. I love the looks of these boats so I will leave the somewhat "factory look"

[tiqueman]

My $.02, paint the carbon white.

[blackcat26]

Yeah thats what I was thinking. Gonna be a pain to "paint around it".

[Jesse J]

very cool work my man! great project - and the first of the twin MGs,

[blackcat26]

Thanks Jesse. Hope my "neutral stingers" are where she likes because they are in there like swimwear!

[blackcat26]

Got the bushings installed in the stingers, water outlets installed and under-hull water pickups put in last night.

[blackcat26]

Got some primer down. Looks alot better than bondo!

[tiqueman]

:popcorn2:

[Make-a-Wake]

Nice work blackcat! Really putting some time and effort into this..............bottom of the hull looks super.:thumbup1: !

[HYDROJERRY]

Hey Blackcat could you post pics of the inside where the water pickups come threw the hull im trying to do my first one and need to see what to do,,,i cut the hole and have a tube but it dont look wright so i dont want to glue it yet...

[tiqueman]

Hey Blackcat could you post pics of the inside where the water pickups come threw the hull im trying to do my first one and need to see what to do,,,i cut the hole and have a tube but it dont look wright so i dont want to glue it yet...

Sorry I dropped the ball Jerry. Your thread has been updated with :help:

[blackcat26]

Thanks for all the encouragement everyone. I'm digging this cat! Hopefully it will do me well.



Hey Blackcat could you post pics of the inside where the water pickups come threw the hull im trying to do my first one and need to see what to do,,,i cut the hole and have a tube but it dont look wright so i dont want to glue it yet...

My first step is to figure out where I want them to go them usually poke a 1/8 hole with my dremel from the inside of the boat out. Next flip her over and masking tape off them sponson and layout the rectangle with a fine sharpie. I then use the cutoff wheel to cut the majority of the area out then use a razor blade and a small needle file to dial the hole size in. The fg or carbon is usually thicker than the lip machined on the pickup so I have to hand file the sides so it sticks out the hull more when installed. I then JB weld the whizz out of it from the inside of the hull. Let it dry a day then bondo the small gap on the outside between the pickup and sponson bottom. Let dry then file the excess aluminum down level then block sand and prime. Hope this helps.

[HYDROJERRY]

Yes sir thank you for the info dude!!!!!

[blackcat26]

Had the day off and got some good progress made today. Got it painted and put some Carbon/Kevlar in the hatch and made some carbon fiber motor mounts and tacked em down. Getting closer.

[johnf]

Looks really nice. Good work.

[blackcat26]

Got the motors in and stuffing tubes installed. Going with the Turnigy 36-56-2600's on 4s. Had em laying around and should bring her to 65-70mph range.

[HYDROJERRY]

Sweet!!!!

[tiqueman]

BC, your making his reeeeal hard to leave mine alone.

[blackcat26]

BC, your making his reeeeal hard to leave mine alone.

Lol yeah it's been a challenging build so far for my little experience. It will either shine or be a real piece. Don't think there will be any in-betweens on this one.

[tiqueman]

Im thinkin itll be just fine.

[blackcat26]

I should be functional by this weekend if everything goes well......

[Jacked1]

I really like the way you did the stingers! Look good and save money, I am for sure doing something similar on my next twin cat!
:thumbup:

[blackcat26]

:thumbup:

Thanks bro. Just remember there is no adjustability whatsoever other than battery placement to try and fly more/less.

[blackcat26]

Got a little work done, not much. There was much debate over twin servo's, so I could lay them down to get them lower but I decided to just do the usual mount. I won't be able to use the tupperware lid anymore. No biggie. Cut down a factory MG strut and filled in the water inlet on the rudder and repainted. Nothing fancy so far just cheap parts that hopefully will haul.

[tiqueman]

That little work is looking nice and getting it closer and closer.

[blackcat26]

Thanks Scott. Got the steering situated tonight. Turned down my drive dogs at work like I wanted them and made some experimental prop nuts with the help of one of my buddies on the cnc lathe. Won't be long now.

[tiqueman]

That looks ridicuolously nice. Youve inspired me to work on a twin boat of mine. Thanks!
As for my Geico.. I only want it to STOP BOUNCING!!!!!

[blackcat26]

Thanks bro. Yeah that bounce is annoying as hell. Mine didn't do it real bad as long as there was a little chop. On dead smooth water it really pisst me off, wah wah wah wah.

[HYDROJERRY]

Whow,, your work turned out super clean and super nice!!!! Huuummm i dont no Tiqueman you better watchout looks like he could give you a run for your money,,hehehe.

[Make-a-Wake]

That looks bad-A$$ blackcat........................:buttrock:

55 mph????

[johnf]

Looks awesome! Can't wait to see what happens when you get it wet.

[blackcat26]

That looks bad-A$$ blackcat........................:buttrock:

55 mph????

Thanks guys! I would say 60-70 range. I have a single MG that has already seen 58mph so I better beat that. This same motor setup went 69mph in my blackjack twin. Weight wise about the same if not a little lighter. Stay tuned.....

[LarrysDrifter]

This is awsome!I wonder how you get a boat that goes 60-70mph to stay on the water?Cant wait to see it run.

[blackcat26]

It's not awesome yet lol. The easiest way to do it is to get it trimmed out good on lower power then apply some serious rpm's! Here is my blackjack twin if you missed it running at 75mph.
http://www.youtube.com/watch?v=JzFcujV1BnA

[RCKong]

this MG is gonna SCREEEEEEEEAM !!! You did a nice job man, It looks like a production model.

[blackcat26]

Thanks Kong. Got her all zipped up tonight. Left the battery placement "open" until I see where they like to ride. Will run tomorrow or saturday unless something crazy happens.

[tiqueman]

Im excited! :popcorn2:

[keithbradley]

Great job blackcat! She looks beautiful...can't wait to see how she will run!

As for the bounce...my PIP cat does the same thing at certain speeds (maybe 30-ish?) but it flattens right out when you give it some power...did your single engine cat still bounce at higher speeds?

[blackcat26]

Keith, it seemed like there was a certain speed that it did then cleared up once it got past that. Maybe around 30-45 then cleared up after that.

[Make-a-Wake]

[MOSQUITO6717]

Can u tell what is the Dark red thing that you used and sand down to smooth surface? I just dont know much about it. What's brand? Thanks

[blackcat26]

Can u tell what is the Dark red thing that you used and sand down to smooth surface? I just dont know much about it. What's brand? Thanks

It's bondo and glazing putty. Pretty common tools for body work. Can be found at just about any auto parts store or walmart.

[ray schrauwen]

Nice work.

What are the dims on the stingers you made or bought?

I can turn some of those on my lathe.

How far do they stick out from the transom?

I will try to read more later, sorry for all the questions...

[blackcat26]

No problem Ray. 3-1/2 long, 1/2 dia down to 3/8" then drilled and reamed 1/4" Will have to wait til I get home for how much is sticking out etc....

[ray schrauwen]

Cool, thanks. I'll start chucking up some Alum.

I wanted to make it a twin at first but, got discouraged after I saw the short transoms.

You could be fine with neutral struts, lets hope....

Maybe I could devise some kind of adjustable strut, we'll see, I'm still not decided if i want to twin her out.

[blackcat26]

Hopefully neutral will work. I was too lazy to make an adjustable set.

[blackcat26]

Got the maiden in this morning, had a few issues. Boat looked good and smooth and handled well. No bounce at all like it's single motor brother. I got into some throttle and looked like getting decent speed and then was getting only half throttle the rest of the run. I am assuming that is the lvc kicking in and will try and run again with it programmed for a lower voltage. Top speed looked to be close to 60 maybe. All in all not a bad run at least it came back to me!

[Brushless55]

keep us posted man!

[forescott]

My twin TC did the same on a set of new turnigy 120's. Half throttle after a minute or so. Unplugged the lipos and tried again. The same results. I turned the lvc off and will try again today. Wonder what causes that??

[wparsons]

^^ It could actually be hitting the LVC, especially if it's set high. If the amp draw is too high for the packs they'll drop voltage under load, even if they're fully charged.

What size props are you running?

Nice work!

[ray schrauwen]

These may fit...

On Ebay three different sellers list them with a slightly different hieght from 22.5mm to 24.5mm.

The 22.5mm will fit without digging into the overhang, I think...

I'll wait until I hear more on the fixed struts, I can make those super cheap.

[blackcat26]

Ray, using 442's detounged. May switch to my 438's and see if there is any speed gain after I get it dialed in. Got my speedy's reprogrammed for no LVC just to see what speeds she will bring. Even riding on the lvc she was probably doing 30 or so! Handled much better than my BJ26 twin but I didn't want to really push the envelope. Didn't get to run again today because I ran out of daylight. Will keep you guys posted and hopefully get some video tomorrow if it runs well. If this thing does not do at least 60mph I'm gonna slap the scorpions in it and run 6s.

[blackcat26]

Got her wet again today with pretty decent but not perfect success. Boat ran great other than sounding like it had a slight miss to it???. Handled well and took a mid fifties blowover with no problem. Got her in and the port side motor was pretty damn hot like 170f. Batteries were hot also about 150f. Gonna look into it further and see whats the dealio. Top speed recorded was 61.5. Not bad but not great.

[Brushless55]

nice speeds!

[forescott]

Boat ran great other than sounding like it had a slight miss to it???.

My turnigy 180 has done that a couple of times. I had to turn off the low voltage cutoff to stop it.

[blackcat26]

I reprogrammed it to no lvc. It was strange. Last night when I reprogrammed one controller didn't program like the other one. That is the same side the "hot motor" was on. Another thing, the speedy didn't give the 4 beeps on power-up. Might have a gremlin in the port side.

[forescott]

The turnigy doesnt give any beeps with the lvc off on mine either. Are you using a Y-harness to combine the esc's?

[blackcat26]

Ok i think i have figured out the problem. Seems the portside motor has quite a bit of shaft travel in and out which explains the heat issue. Gonna replace it after I run today. I know better than to run it like that but wanna get some video of it too bad. Forescott I reprogrammed again for 2.8v lvc and it gives the 4 beeps again. Yes I am using a y harness for the esc's into the Rx.

[blackcat26]

Here is a quick teaser video of some great driving coupled with quick reflexes......
http://www.youtube.com/watch?v=idDzGr_WIak

[Make-a-Wake]

Hee Hee............nice! You'll get it all figured out!

I'll post the vid here for ya.........

idDzGr_WIak

[blackcat26]

Thanks Wake! Just a matter of getting her dialed in balance wise.

[HYDROJERRY]

''WHOW'' when she was upsidedown and you hit the throttle it sounded like a river monster or something!!! I like it!!:rockon2:

[blackcat26]

Well after my mishaps this weekend with the Turnigy motors I decided to get serious and put some power to this baby. One of the turnigy motors deff. had an issue because you could hear a difference in the rpm's it turned. Gonna set them aside and put some real power to it now. Scorpion 3026 1600kv on 6s. Made some water cooled disc's to go between the motor mounts and the motor. Weight wise it's almost identical to the 4s turnigy setup but having such lighter motors on 6s I can get my weight more up front where it needs to be. Going from 475w to 1500w a motor. Should be neat.

[RCKong]

Dang BC your a mind reader, I was going to try to make coolers like that that go between the motor and mount. What would you want to make me a set of those? I wondered how long it would take before you put the power to it !!!

[tiqueman]

Dang BC your a mind reader, I was going to try to make coolers like that that go between the motor and mount. What would you want to make me a set of those? I wondered how long it would take before you put the power to it !!!

Yup, Kong and I talked about that two evenings ago.... So your givin up already and going to have BC make um... wuss! :rofl:

[blackcat26]

I did make an extra set......:spy:

[tiqueman]

Along w/ the stingers you made me.. dude your so nice!

[blackcat26]

Lol I can make those stingers real quick and those mounts are pretty easy also. Wish I had more time to do my stuff at work......

[tiqueman]

And I wish I had access to equipment to do that.

[blackcat26]

I have been doing machine work since 95' and still love it. What's challenging is to try and make stuff in the basement with very limited equipment and low light conditions and a possible hint of beer......

[RCKong]

It's a challenge for sure with limited equipment. I still may try to make some cause I like machining too!
If you want to get rid of that extra set let me know.
RCK

Ok I will keep ya posted. I did a bench test on the system last night it sounds amazingly powerful....

[HYDROJERRY]

Better than the River Monster''SWEET''!!!!!Lucky you can make your own parts!!!!

Alright, now lets see it run amazingly fast :rockon2: :popcorn2:

Quick clip of some bench throttle. Sounds mean.

Wow, love the narration. Sounds awesome.

[Jacked1]

That thing is going to hull a**!! It's gonna be stupid fast as long as it doesn't fly away!

[Make-a-Wake]

Yep..............it'll haul A$$ for sure.

Love the sound as it winds down at the very end of the each rev............sounds like a spaceship.

Yeah man! I think with the balance difference between this setup versus the last one should be about right. Will get her wet as soon as the weather permits. Been raining alot this week.:cursing:

[blackcat26]

Got her in the water today and was quite the different boat than the video! Looked like it should and gps'd at 65.8mph. Not too shabby and everything came back in one piece!

[ray schrauwen]

I see you have your 65.8mph hatch tape on :) good work man!!!

[RCKong]

good call on carbon fiber for the hatch BC - Tiqueman shattered his in a 40mph flip. I'd hate to imagine what it would do at the speed yours is running.

[johnf]

How do those scorpions sound? They sounded insane in the vid!

[blackcat26]

Sounded good. Not as pissed off as I had hoped but good. Will get a real video soon.

I learned my lesson after already cracking one and this new one is cracked now but at least it has some backbone to it now!

Makes me feel kinda funny....

First epoxy hatch is drying now. AND, I found a color that almost exactly matches!

[HYDROJERRY]

Man i just cought up on the thread and the motor test sounds alsume like two little superchargers,,, seems like the speeds pritty sweet too,,,,cant wait for a full vid!!!!

[blackcat26]

OK here is a real video. Not a great one but decent. I think 70mph should be no problem. Gps'd right at 65mph.

[forescott]

Man, I love how that sounds!!

[RCKong]

Runs real nice with those scorpions in there...I told ya !!! 6s right ? I'm trying to figure out if I want to use my 1400kv scorpions in a HOTR twin or in the genesis hull. we all know what a pair of those can do in a genesis . I'd like to get a set of those turnigy 600's
3250W 1400kv motors X 2 = 8.7 hp for the genesis on 8s... maybe too much ?
BTW I did finally get my BJ 26 twin running over 60mph

I would use the scorps in either one of those with no worries. The t-600 is considerably bigger is size and may not fit in the HOTR. I was considering the t-600's in my Thundercat twin. Would be heavy as hell but powerful! Also you can get away with a much smaller esc on the Scorp's. What powerplant did you end up using for the BJ Twin?

[RCKong]

I went with ammo 2600's with SF 120's... the starboard side prop shaft broke at the joint on the second pass,but it was great to see this boat BLAZE across the lake.
I got pissed off at it and had put it up for a while till I got different ESC's. Come to find out my problem was a crappy splitter, the ESC's would not sync. It would not carry enough signal.? A new one with heavier gauge 2 into 1 wire did the trick.
The weight thing is what I'm looking at with the 600's. You could add all that weight and power to the genesis, and still not get it going any faster than a lighter setup with 1/3 the power.

[blackcat26]

Mudl is doing 87mph on his Scorpions......How fast you wanna go?:eek:
1400kv 3026's on 8s..........

[RCKong]

100mph sounds good... LOL

[blackcat26]

Yes it does. Maybe one day I will shoot for it. Funny you mentioned about the esc split wire into the receiver. When I ran last time I noticed a slight difference when giving it low throttle, like one motor would start before the other one. When I brought it in after I ran I noticed that one motor was hotter than the other also. Same side that got hot the first time I ran it on the turnigy motors. Wonder if the small wire I used to join the esc's is to blame?

[RCKong]

yea mine was real noticeable, with the motors not running together, made the boat near impossible to drive.
BTW I just found these;http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=5420
interesting little motors, for under $20 almost 800W and 2900kv

[blackcat26]

They sure do have some puny wires on em! I took my t-120's out and put in the hobbywing 150a heli's today. Water was dead calm and only got 61mph but both motors were the same temp when done! WOO HOO. Changed the timing and was gonna run again and noticed the servo mount was loose. Will get another run soon on the new timing to see what happens. This thing has some serious acceleration!

[RCKong]

Check this out - I just improvised this motor cooling disc from a old nitro motor.http://img641.imageshack.us/img641/8874/1007772.jpg
Now I have to find another one.

[ray schrauwen]

I wanted to do that too, just didn't know which one?

[Jacked1]

I might try that with one of my 40 billion 3.5 k&b motors i have laying around!

Good idea Kong!

[RCKong]

Thanks, I had to come up with something for it. This thing fit nicely after I drilled out the holes in the cooling head a little
Anyone with a junk traxxas .15 marine engine ? I'll take it... I was also wondering if a proboat cooling head would work.

[Jacked1]

Haha I have one! But I might have to use it for the same thing!
I used mine in the first boat I ever built and in a car with a home made radiator after getting a hole in the side of the boat the size of my fist after the clutch flew apart and I was mad! Haha

[ray schrauwen]

Hello, first I want to apologize for making that offhand remark "Dude". It was meant in fun and I really meant to or should have praised you.

That said. I would really like to know how much strut is sticking out please. That and possibly the distance the motor mounts are from the transoms.

Thank you.

Best Wishes

[blackcat26]

Man Ray you sure are nice when you need something!

[ray schrauwen]

O.k. How much Paypal is going to cost me now...? LOL...

[blackcat26]

Ok rayster the motor mounts are about 4.5" from transom and the stingers are hanging out about 2.4. Just need em long enough to clear the very back of the boat. Be careful, I don't ever recommend following my builds. lol

[ray schrauwen]

Thank you. I must say i was leary at the fixed stingers, then the 65mph came and i said WTH!? Gotta be worth a try.

Less to adjust etc... I suppose.

I have a Pair of ARC 3655 2800 KV motors on 3S & 4S With DT cupped 442's.

It looks nicer without adjustments too.

[blackcat26]

Yeah man. I do like not worrying about a blowover tweaking a stinger and having to tune them. When it's fixed, it's just there and all you can do is play around with the COG a little. Makes life easier for me. 2800's on 4s should be pretty quick maybe around high sixties to seventy range.

[LarrysDrifter]

Blackcat,I wanna see another twin build.Maybe a mid 40" cat.What about twin Leopard 5692's on 8 or 10s?Theres some place in Europe that makes big twin drive props in the 50mm and up range.

[blackcat26]

Funny you should mention that. I was considering selling off most my stuff and chasing the 100mph mark...Either that or keep everything and build a small twin cat like a micro iceberg or micro drifter. That would be a cool project as well.

[LarrysDrifter]

If your chasing 100 might I suggest a rigger?I dont really care for them since they dont resemble an actual boat,but I think blowovers would be minimal.But,if you can make a cat stick at 65 or higher,you can prob make one stick at 100mph.

[blackcat26]

Here is a clip of some on-board video I took yesterday.

[ray schrauwen]

Nice! souns like turbines.

[HYDROJERRY]

I was thinking super chargers but very cool,,, i have one of those mini keychain camara's but have never even hooked it up maybe i should just to charge it up!!!!

[roadrashracing]

id did not where to post these, I seem twin tubine was done already:popcorn2:

[blackcat26]

Yeah I don't have the coins for a real turbine.....I will have to settle for a partial turbine sound for now.

[calcagno45]

Any updates?

[blackcat26]

Not really. I was debating on different motors for some speed but I have some abc 3-blade's coming in next week. I will test some with those and go from there. If I don't get a decent amount of speed I will move to 1800kv's or 2000kv's. When in need spin it faster!

[blackcat26]

Hull for sale in the swap shop. Your chance to own a one of a kind boat!

[bea5017]

i wish the would put some thicker wire on those scorpions, i melted one of my 1900 3026's... wasnt pretty

[blackcat26]

Had no problem with mine. What was your setup?

[bea5017]

2nd gen skunkcat x2 1900kv 3026 scorpions, 5000mah 5s 40c flightmax to each motor, wit aquasatr 120's. Lucky the esc survived. i got around 20 good runs with her untill she blew..

[blackcat26]

Strange. I have had bad luck with the Aquastars. I blame them on whatever I can.:laugh:
