Fighter Cat Riversport Catamaran

looking good.

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.

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.

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

[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

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.

Sweet.Cant wait to see this one move.

FYI- the 440 & 442 are excellent high RPM props for this hull. I ran the 1512 2650 on 4s with 440 and it ripped at nearly 60mph. Had a nice fluctuating "sweet spot" and didn't have any wind up slippage from a dead stop.

Looks nice, Looking forward to it finished with a video

Thanks. Vid will be a little bit. We are still covered in snow here in Michigan at the moment.

Build is coming along well though. My 1.5y/o daughter must have gotten a hold of my camera, it doesnt work right now...thats why I havent updated with pics lately. My wife has a camera I can use though when I need to post. As of now, I have the esc in, most of the cooling lines ran, and I made some cuts under the hatch so I can get my batteries in. It wasn't even close before I started cutting.

I just received my order of 2 "bling rockets" (25" Fightercat mono hull) yesterday. My son and I are doing side by side builds of these, its his first build of any kind. Naturally he is chomping at the bit every moment to get these going so Im working on those at the time. When he goes to sleep, if I get a chance, I work on the riversport and my 50" mono I am in the middle of building. Nothing like building 4 boats at once!!!

Getting close...I mounted the servo, ran most of the cooling lines, and cut enough out to get the batteries in. I still need to clean up the area I cut a little (there is one spot that I cut a little much w/the cut off wheel...I'll have to poke a little glass in there and smooth it out). Also have to make a water exit line to come off of the motor (not using the mount to cool) and I still want to make a aluminum pad to mount the esc on. 80A will be the lowest current rated esc I've ran to date in aftermarket applications, and if it cant handle it I dont want it to destroy the hull and carbon fiber.
There is some fiberglass dust in the hull still. I sprayed it with the air hose but there are spots (like on the front motor mount, behind the coupler) where you can see the dust. It's just dust and will wipe off.

I finished the water lines and outlet. I mounted the outlet where it would be out of the way and I wouldnt have any lines running across/under/over the batteries. It will spray up rather than out, but I think its far enough away from the prop that I will still be able to tell if a steady flow of water is coming out...
This is pretty much the finished product, other than I still plan on making an aluminum plate for the esc to sit on, but you wont really see that much anyway.

Im curious what everyone thinks of this and would love some feedback. I've tried to do some more original things on the boats I am building right now, but I also didnt want to add any unnecessary weight to this one since Im already running 8s in a rather small (32") boat.

looks nice Keith. Interesting with the water pipes laying in there. what rudder are you using?

[JPriami]

i see it now in a pic above
