Was wondering if there is a shaft system like the NTC3's where a CVD type shaft is available instead of using the flex cable for turning the prop? Otherwise, I'm gonna have to start from scratch on the Lathe machine and figure something out and make my own constant velocity joint.

I envey you if you own a Lathe. :drool: you can make soo many things.

I rescently contemplated mounting an airplane propellor to a nitro car engine. I really don't know the mechanics of such an idea, but it would seem similar to the boat thing. Surely, someone else has done this?

Good Luck,
Rob
 
Yup got a Lathe, buffing machine's, sandblaster, band saw and all the welding equipment needed (Tig and mig) ... everything that a shop needs. The only reason I have these things is because of the family business. We do surgical instrument repairs.

Currently I am thinking of making a lightweight chasis for my NTC3 out of thinner aluminum sheets with stainless rods for strength and support. seems possible.
 
Hey Diver - send pics of your work for your NTC3 when you do it. Would be very interested in some custom work if the price is right.

In particular, right now I need some custom dogbones made for my CyberMaxx :thumbup:
 
Christain,

ANYTHING is possible. As far as the chasis for the ntc3, I'm thinking of VERY thin and lightweight aluminum. Basically just there for the mounting holes. Then stainless steel supports. In automotive terms, I'm thinking of a tubular space frame with very little flex because of the x type supports. Gotta make an initial mockup before I can really get a move on it. You know how it goes in any hobby, if you can't buy it, make it!

I have a new chasis from where I am making the initial template out of ... just for the dimensions.

Also in my head, I was thinking of making a slightly extended chasis since there is room in the rear of the lexan bodies. Since a lot of the bodies don't have the cut outs made for the rear wheels, there is a little room for stretching and sectioning of the chasis. OH BOY, the gears are turning and I gotta get it all down on paper before I forget!

As far as dogbones, I am also thinking about that too. Probably gonna make them out of surgical stainless steel since I have a lot of blank stock here. Maybe even making custom cvd's for the Supernitro rally that I'm gonna use for a trainer car. AKA, for those that ask, "can I try?" when I'm playing with my ntc3. Sound good? :write:

Click to expand...

Well, that's how they break in a lot of car engines when they don't wanna mount the engine on the chassis.

They attach the prop to the engine. When they run it up on rpm, it creates a load on the engine. You can buy break in kits....somewhere.

In some issue long ago, they showed one.
 
you can use a cvd in your boat its easy to do most of the parts are off shielf items if your LHF is into boat racing. The big thing you will need to do is beef up the hull where the stuffing box is to take the added pressure from a CVD drive. Its a simple dogbone setup as long as the engine is at the right angle you should find it simple to do. If you need links Ill find some for you.
 
That would be great! please post some links, I would greatly appreciate it!

Thanks Hunter, I know that the later of the 3 listings I can't use since those are for .19-.21 enginges. The engine in this apache is 22.5 cc. The first 2 look promissing. 1/8" - 3/16" sounds right but I'm gonna call dumas boats just in case. This is my first build and I really appreciate your input.

Can't wait to get this Apache 50 running! Wonder what the top speed is gonna be with the proper trim tab settings along with the 22.5 cc engine. Makes me get goose bumps just thinking about it!
 
For now, this is my only boat. At a cost of at least 1K /boat ... it'll be my first boat for a while ... or at least until I can find a sure way to keep my butt out of the dog house when the wife see's me playing with something new =devil
 
he only reason I asked is because gas boat=running out of gas in the center of the lake :( I go to where all the gas boats run and do tug servive for them with my tug. so you might want to think of how your going to get it back when the gas runs out.
 
I thought of that too. Running out of gas in the middle of the lake is a whole different story when compared to your on/off road running out of gas in the middle of the parking lot or track. :doh:

There are really no areas here for r/c boats so I guess I would have to bring a rubber dinggy out with me!

Actually, I would only really be able ot run this thing our in the marina where we launch our boat. I know, salt water corrosion, but since this thing is water cooled, I will be rigging up a fresh water flushout through the water pick up. Pretty much just like we do for our boat.

Other than that, the only other water here in my vicinity is the lake at flushing meadow park. I'll just have to make sure that I keep an eye on the fuel levels every few passes and keep it close to shore.

Otherwise, I'll have to put my swimming abilities to work. :depress:

I asked my LHS if there were any areas where other r/c boat owners frequent, they still have to get back to me on that since there aren't many of them around here.
