55" Segad Gas to FE build...

[Rob DeAngelis]

So here is the plan... Swordfish 240 and Leopard 5698 910kv 10s in series... :cool2: Here are some picks of it as is now after the reremoval of the 26cc gas engine and muffler.... 73123 73124 73125 73126 :tiphat:

[Rob DeAngelis]

Some more pics... 73127 73128 The shoe is there to show size lol... its a size 12 btw

[worriedsick4u]

Nice. Hopefully you got a deal on that boat. They're about $1,200.00 right? And then stripped to the hull. I like it. Good luck Rob. I have a big stash of parts. Let me know what you need and if I have it I'll shoot it down to you.

[Doby]

Thats a bit to high of a KV motor for 12S.....10S (or even 9S) would be more suitable.

[BW won]

Why do you write that, Doby?

[Doby]

3.7V/Cell
12S=44.4V
RPM= V x KV.......in this case 44.4V x 910Kv = 40,400RPM

Usually 30,000ish Rpm is used as a rule of thumb for racing, 25,000ish for sport running....with 40,000 that set up is in the SAW catagory.

For a quick reference, a "Volt-KV-RPM" Chart can be found at on FC's web site under "Fast Electric Resources."

Ya I was going to point that out also John - a 730kv 5692 would be a much better choice of motors .

Rob where did you order the hull from .

[Rob DeAngelis]

Ya I was going to point that out also John - a 730kv 5692 would be a much better choice of motors .

Rob where did you order the hull from . I bought the boat complete on ebay... 800 shipped... now im selling the gas engine and muffler and tank to fund some of my build... so far I got the 5698 910kv off ose

[Rob DeAngelis]

and why would the 5692 730 be a MUCH better choice?

[dana]

I can't wait to see how this turns out

[Rob DeAngelis]

:thumbup1:

[lenny]

More torque and better power for bigger props and I think more efficient.

[Doby]

and why would the 5692 730 be a MUCH better choice?

Lower KV puts you in a safer RPM range.

[Rob DeAngelis]

Lower KV puts you in a safer RPM range. dont tell me that :frusty: I just ordered a 5698 910kv last night!!!

[Rob DeAngelis]

I will make it work... You shall see!!!! muahahahaa

[dana]

Yeah run 10 s

[Punisher 67]

and why would the 5692 730 be a MUCH better choice?


Its a better fit for a 12 cell setup - not that its any better than the 910kv motor but they both have there sweet spots battery wise . John ( Doby ) pretty much hit it on the nail for you with the RPM description infact on a boat that large with a 60mm + prop even as low as 20K will get you into a safe 45mph range .

[Doby]

I ran a 435Kv motor on 10S in a few different boats and got them all into the mid 50's...of course it was turning a paddlewheel of a prop!

[Punisher 67]

Rob - Me and John are not trying to come off as "Canada's greatest know it alls " but with the big boats between us I am sure we have been there and done that.................:laugh:

[Doby]

Rob - Me and John are not trying to come off as "Canada's greatest know it alls " but with the big boats between us I am sure we have been there and done that.................:laugh:

Ditto..I hate people that think they know it all...its upsetting to those of us that do:drool:

Anyway, if you reduce your cell count and watch your prop size, it should work out. Looking forward to seeing how this build progresses!

[Rob DeAngelis]

Im just going to take my time and research as much as possible... its my first "real" build so im going to be very cautious....

[Rob DeAngelis]

Next step is to reinforce the hull insides with fiberglass, seal all holes with silicone and paint the insides flat black... I will have the pics up soon...

[Rumdog]

I think Jim Marcum on this forum has converted one of these to FE for SAW purposes. He may be of some help to get her handling good.

[Punisher 67]

Rob I am really curious on how your build goes - I would of liked to have done the king of shaves 55"

[iamandrew]

Hi there Rob, yeah one of my friends runs the same boat but KOS, and after a year, the hull has actually deformed a little bit and is very flimsy. Also, when he rolled it, it smashed the entire hatch in, so dont forget to reinforce that too
also the stock strut setup has bearing in it..... :S

[Rob DeAngelis]

[Rob DeAngelis]

Rob I am really curious on how your build goes - I would of liked to have done the king of shaves 55" ya the kos is nice but I just think the Segad finish looks better... and also the build is going to be posted every step of the way... as of now im laying down the fiber glass and sealin her up... throwin a little flat black as well to the insides...

[Rob DeAngelis]

73324 73320 73322 73323 Well I got the fiberglass job done... Heres some pics.... With help from a friend...

[worriedsick4u]

Looks good Rob.

[Rob DeAngelis]

Just got some goods!!! 73464 :thumbup:

[Rob DeAngelis]

Next steps.... OS rudder, ESC SF240 and X600 prop... then create boxes for the lipos and figure out my cooling line paths...

[Old Sloppy]

910 KV, is that 9s lipo ?

Harry

[Rob DeAngelis]

Well the hatch is done... It came out good and strong... Now just waiting on my parts...

[Rob DeAngelis]

910 KV, is that 9s lipo ?

Harry Im planning on running 10s to start then try out 12s... propped with a X600, the speed calculater on this site its claiming 82 on 10s and 91 on 12s... (mph) ................................... We shall see

[Rob DeAngelis]

73732just imagine this!!!! 73731 Duh I kinow they are dif motors... Just saying I got plenty of room... hahahaaaaa

[Rob DeAngelis]

Ok back to reality... heres the real set up.... lep 5698 910kv and a sword 240... 73733

[Rumdog]

Looks good... now ditch that radio box!

[Rob DeAngelis]

Looks good... now ditch that radio box! keepin the box for now... its simple and water tight...

[nata2run]

Looks good... now ditch that radio box!

.....and add second motor.

[keithbradley]

Good luck with the build Rob. I've thought of doing one of those many times.
I like to run higher RPMs than some people, but I agree with the Canadians...that motor is better suited for 10s. In a boat that size, turning a larger prop at a slower RPM can help get the hull out of the water and lower current draw.
Ever thought of running twin? You could put two of those in there...

[RCKong]

man thats an awfully big hull for that single motor... I was looking at one of these hulls on ebay last week and was curios if it had enough transom behind the sponsons for a twin drive ? I found a set of these on FC site and wondered if they would fit.

[JackBlack26]

Looking awesome! Im looking at a BJ 55 hull myself. Can't wait to see it run!!

[Old Sloppy]

10s is where im going to start out... lets see what happens...

I do not want to sound like an arrogant prick, but I can forecast 10s will over rev and overheat your motor.

I did that myself reciently, I ran a 10s setup with x450/3 prop and let the smoke out of the motor.

Plett 370 HP/50BM A1s rated at 4.4 KW, it cost me $585 USD to replace the motor.

Thank GOD I had a 40-160 ESC it works fine.

Nice boat Rob. Now shoot a video of its maiden run. Make sure you catch that gps.

[Old Sloppy]

I too want to hear that GPS result.

Hey, What prop did you decide on ?

Harry

[Rob DeAngelis]

im going to run a x670 a prather 265 and the stock ss prop for now...

[Chrisg81983]

A little large on the props don't u think especially to start out I have the same exact setup in a df-41 run it on 8s most of the time and sometimes 10s and after seeing data logging results with a x560 on 8s there is not to much more safe room for sport boating you want to run gasser props on a Fe setup I would just think that over I could never see putting my s275 on my Leo 5698 u can do what u wish but it sucks to smoke something on maiden run i hate to burst ur bubble but u will see nowhere near 80 with this setup Fe calc does not take in consideration your hull size and many other important factors look at your thread from the beginning and really read what everyone is telling you and take their advise wisely I am not saying all this to be a dick it's that I would hate to see this turn out bad for you after you did a such a nice job with this conversion good luck and interested in seeing the results

Welllll???? Any news on this? How does it run?

[carlcisneros]

Well, from what I have read, if he does not take the folks advice and goes with
the prop set up he wants to use, then he has no one to blame but ,,,,,,,,,,,,,,,,,,,,,,,,,,. (just my opinion)'
I for one hope he takes the advice and doesn't smoke that beautiful boat up to kingdom come.............

The boat is so dang nice looking, I would hate for it to smoke on its' maiden voyage.

always start small and work your way up checking temps as you go.

[Punisher 67]

Well I have to agree with the general consensus about the props in question , I always start small even though I know for sure the motor will handle larger or just go with a lower cell count on the first run . If there is a video I certainly would love to see it .

[Doby]

Hi Rob,,,just a bit of FYI...I have numerous runs on my 42" cat with the 5698 (835Kv) on 10S and its pushing my porky hull into the low 60's and has been averaging around 120 deg after 3 minute runs. Seems to be a good match for the hull. looking forward to eventually hearing how it does in your larger hull.

[Prop-a-Gator]

Hello Rob, this has been a nice build so far. Start to finish in about a month is pretty quick in my view. I'm fairly new, but I haven't seen too many single cats that size, so I'm tuning in. Makes me wish I had more room in my 37" Daytona. Good luck!

[BW won]

His SF240 didn't even turn on- wasn't the soldering either. So, senor Rumdog, there is no new news other than SF suck! I had a SF burn out on me too- had to spend $16.??
to ship it back to China. Although Steven V. offered to send it back for me, It wouldn't ship-out until 3 week later. BTW, bought a castle hydra ice 240 and it works as a $255 (thats right!) ESC should- flawlessly.

Ive had a number of SF240s...work fine for me...very tough ESCs.
Glad to hear the castle is working out for you though.

[Chrisg81983]

BW Any time I sent steve back something he sent out the replacement within 2 days so why would u say 3 weeks was he out of stock or something like that

[BW won]

BW Any time I sent steve back something he sent out the replacement within 2 days so why would u say 3 weeks was he out of stock or something like that Perhaps he is out of stock- but he offered me the option of sending the ESC to him, because he had a package going to Hifei in 2-3 weeks.

[BW won]

So, since you say the Castle works good, he must be running the boat, no? Or YOU bought a Castle? The Swordfish esc's are far from junk.
I'm no Senor Rumdog I'm not sure what the confusion is... I have a boat that I am running with a castle 240 I just bought to replace a bad SF240. Rob has yet to run his boat... As far as SF, Perhaps Rob and I are just unlucky... Or, maybe it has something to do with the date of manufacturing ( just a guess)..

[BW won]

I agree "You can send the esc to me. I have a package going to them in about 2-3 weeks. Or you can send it directly to them. Either way, in the instructions there is a warranty form that needs filling out.

[Rumdog]

That doesn't mean you had to wait 2-3 weeks. Steve probably would have just sent you a new one.

[BW won]

After getting the reply (I just posted) from Steve, I made the obvious (to me, at least) inference: If I had sent it to S.V. I would have to wait 2-3 weeks to have it shipped to China, then wait for it to be fixed and returned ( another 2 weeks, at least). So, I paid the $16.?? and saved myself 2-3 weeks of wait time. Either you're exceptionally optimistic, or... IDK how you would assume that from the reply S.V. gave.

Are you going to run the SF 240 or the Castle ESC? I have two of the 200HV Ice ESCs to use in one of my builds. I'm hoping castle has the bugs worked out of them. The data logging and over-current shut down are awesome when the ESCs work correctly.

[Rob DeAngelis]

my friend bw won had the sf 240 and it smoked after hitting the throttle once... I was there with him when it burned... it was pretty sad... and to top it off we hooked my sf240 to my pc for the setup and it didnt even turn on??? we even hard wired it to check if it was a connector issue and still nothing... Hes been running the castle 240 on 8s in a 41 fighter cat with a 5692 lep and has had no probs after about 9 or 10 packs... hitting around 70 on a garmin gps... btw the temps were low... runs great so thats why im goin with the castle for now...

ya it does... the darn thing didnt even turn on... even tried to hard wire it to see if it was a connector issue and still nothing... thats why im not running yet... sucks spending over 200 bucks on a D.O.A. esc that your thinking is going to be perfect for the job.... its like a wrench in the gears man...
Sucks about the Swordfish........

[Chrisg81983]

I been running castle ice controllers since they came out and I must say they are just about my favorite. I am using two 200 Hv for a build I am about to do and currently have them in several other boats and they all run flawlessly. I also have good luck with the sf 240 Hv the only thing is that you half to be real careful with the timing with the big leopards I know many people that smoked them running to high if timing.

I had great luck with the ICE 100s, went 74mph in my EKOS with those which is pretty good for 100A ESCs. I also loved the original 160HV and used one in multiple boats. My luck ended with 120HVs when they first came out though. Ruined a beautiful hull at the hit of the throttle onn HV (nasty fire, not just a failure). A lot of those ESCs were faulty from the start, that's what prompted the recall and release of the "ICE2" ESCs.

That's too bad. The SF240HV has been a resilient ESC for a lot of us...maybe they had a bad batch.

[keithbradley]

a good example is danas post #91 on this thread... look at it and you will most likely get mad.... he does stuff like that to all not just me...
We won't all love each other bro. Some people just won't get along...best to just stick to the boat and the people you do get along with.

When do you plan on running this thing? Are you going to get some video? It looks like you do decent work based on the pics of the boat...I'm looking forward to seeing how she runs.

Cool!
Did you read the data logger when you were done?

Looks good glad it went well just needs a little fine tuning but why at the end it sounded like it reved out and was not moving ( for time frame around when you were talking about the 8s ) it could of been just my speakers though for some reason there was alot of distortion on my end Chris

[Rob DeAngelis]

thanks man...
Good job Bro. Happy for ya.

[Doby]

Looks good, a bit loose perhaps, but with some tinkering, it should settle down....Question....what was with the last few seconds of the vid....it was just floating there..hope everything is OK...any idea on temps for the setup?

[Doby]

Never mind...drive dog issue...duhh on me for not reading all the posts...

[Rob DeAngelis]

my drive dog came loose "again".... no biggie... temps were low on the next run that I ran out the batts @ about 5 minutes... I will have the data log up soon

Cool...if thats on 8S, I'd be afraid of keeping it on the water on 10S....its hauling some serious butt the way it is...

[Doby]

As this thing obviously has some serious speed potential, have you considered adding expanding foam to most of the open cavities in the hull? If used properly it can add a lot of structual integrity (as well as flotation) and can help prevent cracked/folded hulls in the event of a flip etc at those speeds....just some food for though to help keep it in one piece. I foam all my hulls the great success and no issues..

[Rob DeAngelis]

thanks for the info... today was kind of a rush / get it in the water deal... but as for now i have some noodles in the upper ends of the boat... def going to work on some flotation as well as set up...

Try a smaller prop (especially if you're going to go up in voltage). I bet if you go down a couple sizes in props the oscilation will be gone (the bouncing of the front of the boat and the boat coming out of the water). It looks like that prop is lifting the hull out of the water no problem, but you would be surprised how much better it will handle with a bit smaller dia prop...

[Rob DeAngelis]

thanks bro... im on it... what do you think of going with a smaller dia but 3 blade?

You could...I personally like two blade props better in most applications. Usually in terms of mph/amp, two blades usually win out for me.

[avinash inalsingh]

now saw the video!! kicks ass...my experience with large cats, a 3 blade prop is better..but i guess everything is trial and error..i changed the height of the prop setup to a shorter one...centre of the shaft is exact height to the bottom of the sponson.(pontoon) well done i am waiting to see what i will do >>

What was the strut height before? I would raise that sucker up above the sponsons

[Old Sloppy]

I would raise that sucker up above the sponsons

centerline of propshaft 3/8" up from bottom of sponson. (may run even higher as needed.)

hi ia new to this site and electric boats....my set up is 58 seged cat scorpion 4035 800 kv motor 300hv swordfish esc and 2x 6s 5000 40c cells(12 cell) what size prop doo i start off to use? any help ..thanks avi

[forescott]

Yikes! 35,500 rpm. That scorpion is a torque monster. I'd drop down to 8-10s and use a bigger prop.

[avinash inalsingh]

i didnt try any props yet...so i dont have an intial size...i already set up for 12 s and i dont have other batteries.........do you reccomend 2 or 3 blaade prop? thanks

[lenny]

What props do you have on hand ?

[forescott]

Thats just a lot of rpm for any fast electric setup. usually around 25,000 for sport and 30,000 for race. If you insist on running 12s use the smallest prop that would get that big hull on plane. I have the venom/atomik brushless 55" cat and it uses a 50mm 3-blade, but a 2-blade will spin easier at the same diameter. Whatever you do, run it for 30-seconds to a minute, then bring it in and check the temps. Your motor and speed control are quality products, but you definetly dont want to burn anything up. I would spend a hundred bucks and get a pair of 4 or 5s packs.

[Old Sloppy]

Yea, Drop your cell count for sure.

You guys missed the boat! The motor you need to be looking at is on horracings web page look at the SSS5694! It runs on 12s and is a 1200kv motor. It's rpm rated at 50000! The big motor with specs like that are made by TP Power. These Motors only sell for 105.00 plus 24.00 air frieght that will cover a pair in the shipping I believe. I got mine in a week state side. It comes with water jacket as well.8962789628
12s x 3.7 x 1200 = 53280 rpm
I run this motor on 8s and it hauls the MAIL!!! I think that puts me at 35520 rpm safe and wow talk about power this is a 6 pole motor.

[Rumdog]

lol. Come on, dude. You're not going to run 12s on a 100kv motor... especially in a friggin boat!

Hello

some news from the big cat.

Motors and escs changed

I replaced the lehners 3080 and Atos escs.
Now two TP 5850 9D 820KV and two Hifei Swordfish 300 pro are mounted.
I want to try if such little motors and china escs are strong enouth for the big monster cat.
First testing runs very good.
Temperature is normal.
Here some photos from the new inside of the mystic and a running Video with the TP motors and the 300 hifei on 12s Lipo with a 60mm steel prop 1,2 pitch.

I took the above (MHZ Mystic 240) from a build that is here as well. It is a 94" cat
I love a good laugh and it seems that this video covers that pretty well. here is a picture of the SSS5694 in my custom built by me, 1/5 scale 4x4
