Yes, another Catamaran Build!

[ace028]

Bonewar, thanks, I will hopefully finish it soon, I can't wait. Your cat is looking pretty nice to btw.

I'm gonna have to thicken up that transom, you can see where it is thin by the corners, maybe I lay some fiberglass cloth on the inside.

looking good I am trying to build up some motivation for mine if I can find some time

[peells]

I just can not believe how bad photos make the hardware look, GUYS that hardware has a see yourself shine to it it has been highly polished and photos do not do it justice (I just thought I would share that) so if you guys like it in the pictures in person would be awesome!!! Wait until you see my next build (twins)

[ace028]

Small update, just bought 2 motor/esc combos. 3600kv motors and 30amp escs. oh and the best part of all, a free gift!!!!! here's a link http://cgi.ebay.com/ws/eBayISAPI.dll...MEWA:IT&ih=006

3600 is a little more then I wanted, but I couldn't make up my mind, I wanted the intregrated fan and the esc with it. my other choice was like 3800kv, which I think may be too hot. But maybe by having 2 motors pushing the boat will not be as much strain on the motors then on one motor. I can even run with a 2 cell pack and still be fast. Most likely I will run 2 3s in parrallel, hoping for extended runtimes. Oh, and I can use the 3mm to .130 coupler from OSE. I just need to buy 2 motor couplers, 1 reverse cable and 2 3/16 to 1/8 stubs. Then I can mount the drive lines and finially cover the top.

Speaking of covering the top, any thoughts on mahogany vener for a final finish? I was thinink it may be cool to make the boat look like something that was built back when boats had beautiful wood finish.

If not that, I have bright orange, and orange red metallic, color change from magenta to gold.

looks bad @$$ keep up the good work

[ace028]

Thanks.

I just tried my 3/16 shaft in a peice of brass tube (I think 7/32) it fits very well, just like a lead teflon bearing fits it. Anyone run it like that before, straight in the brass tube w no bearing?

[ace028]

I forgot to ask, would it be a good idea to add material to the rear steps, making them sit "deeper in the water so to speak? Like ride pads.

[Avanti]

you mean make them flat like the majority of the r/c hull out there?
I thought about it but I am going to try them sharp like a full scale boat first and see what happens.

[ace028]

I mean if you were to put a ruler across the steps on one side, they are all even, but make the last one larger then the rest. I covered all the steps with 1/64 ply, so the last one add 1/16 balsa to the covering to make it larger then the rest if that makes sence.

[Avanti]

No you would not want to do that it would defeat the purpose of the steps.
The steps on this design are more about letting air into the tunnel for lift.
If you were to make any of the steps taller it would be the front one then the boat would run like a hydro.

[ace028]

Ok, thanks, glad I didn't do anything to them. I can't wait till my motors get here.

So living in florida, you must see lots of awsome boats. One of these days I'll have my own real boat.
I work with a guy that is from florida, we are MB techs.

Did you make any progress on your cat?

[Avanti]

not much progress on mine but I did pick up all my drive hardware.

[ace028]

Not much progress to report, I am still waiting for my motor/esc's. Hopefully I will see them on monday. But I did rip off the 1/64 ply I had on the center section, and used balsa instead, it will make a better transition to the sides where it curves up level with the top deck/sides. It looks a little better then what the pic shows, still lots of work and sanding to be done, but I can't go much further till I get the motors. I also bought a durbro tube bender, it makes very nice bends, so once I place the motors, I can then start the water cooling plumbing.

I need to buy a better digital camera, but that will wait till this build is over.

[crazzy maxx]

looks great.

if u where to make any part of that hull thicker it would be the center(betweebn the sponsons) my dad did that to his bopat and it lifts the boat out of the water more and it will decrease porpois

[ace028]

I'm thinking I may lay some fiberglass on the inside of the center. I'm interested on seeing how the center tub trim tab works on advanti's build.
