Fighter Cat Riversport Catamaran

Sweet.Cant wait to see this one move.

Come to think of it, I ran my Triton with a Leopard 4082/ 1300kv on 8s and a x442 and it did quite well. I dont remember the exact amperage but I remember it being surprisingly acceptable.

[keithbradley]

Yeah if I had a lower kv (little) motor I would use it, but this is the lowest I have besides motors that are too big for the hull. I'll just be turning a smaller prop, probably start out with a m440. Hopefully it does ok with that small of prop. Ive ran that kind of RPM with a larger prop, but it was on a larger ESC as well.
Part of the reason I am adding an aluminum mounting plate is to protect my carbon fiber if something goes wrong!
It should give me pretty good run time with the higher voltage if nothing else

[LarrysDrifter]

8s on this guy?Thats alot of voltage.I hope you post a video.

Not a whole lot happening lately. I've been torn between two builds. I got the esc for the riversport in, which is now a Fightercat suppo HV esc. I intend on making an aluminum mounting pad for it and running aluminum cooling lines to the esc and motor.
Plans are now to run on 8s1p. I will have to trim the sides (under the hatch) a little to get my 4s/5000mah packs in there but they should fit.

I just found these fighter cats the other day. Man they are good looking hulls, I am very impressed. I wish their carbon fiber ones were available.

[JPriami]

looking good.

Some more progress...
Going with a Leopard 3674-1300kv motor and scorpion 120A esc with water cooling added. The scorpion escs are really nice, loaded with features (like over current shutoff, ect) and they are programmed with a card via infared signal. The suppo escs are a great deal, but since this is going to be my main "sportboat", I decided to go with something a little more fun.

Ive got the rudder/strut mounted. I drilled the bushing in the strut for .187" flex and used a proboat flex from OSE.
Stuffing tube (1/4") and motor mount are also mounted.
Here are some pics:

Wow, that looks nice!

[LarrysDrifter]

Nice.Get her going.But dont hurry too much since the water is frozen.

[keithbradley]

Ok, the holidays are over...I guess I will get SOMETHING done. I did my second and last layer of carbon fiber/kevlar today. It was still wet when I took the pictures so it has a glazed look to it. Its actually a blue/black weave, but the blue doesnt show up that well in the pics.

Thanks for the input guys!
Ben- I will need to get a coupler for her. Im not too experienced with wire drives though...do they have to be close to straight? The stuffing tube is going to have a little bit of bend in it no matter what I do.

Some would argue, but I've had some pretty good luck running wire drives on the Genesis and Apparition single motor setups. I've only broken 1, but found that the motor angle was misaligned and pinching the wire.

PS- I also have the horizontal aluminum servo mount.

Cool! Nice Looking Hull! =)

You can go .078 wire if there's any doubt about the 4mm cable holding up. Although the 4mm is a bit bigger than the .150 cables and doesn't have the torque twist since it's 2 pieces so might be able to handle a good bit of load.

BTW- I have the 6mm couplers now if you need them. 6mm - 4mm or 6mm - 078.
