Convert Shockwave 26 (Proboat) to Air Boat
1 Attachment(s)
As title says...
I have a Shockwave 26 hull thinking of converting it to air-boat. (I have radio gear + servo + brushless + prop + esc from other rc stuff) I would really appreciate your opinion. Does this worth the effort? What are to pros & cons of this kind of conversion? Thank you for your time Alex this is the boat: http://www.rcuniverse.com/forum/atta...mentid=1907115 |
How wide is that boat.?. not sure it would work well, might just twist itself round and round
|
Thank you my friend for your reply...
Well the dimensions are: 7.4 inches (19cm) wide 26 inches (65cm) long I read somewhere the ratio for an rc airboat is 1.75 (long : wide ratio) My boat ratio is 3.4!! I think too narrow.... is this correct? |
Not sure about the ratios.. my foam boat is 30 long 11 wide flat bottom and on ice i have torque flipped it with the motor at stock height now my motor is .25 higher and a 9.8 prop so i know i need to b carefull, on land and thr floor it is not a problem but on ice i ned to throttle up slowly...
But you have a deep v im just thinking it will b top heavy but try it thats all i can suggest and the fun part of it.. but i dont think it wil work... |
You made me thinking...my friend....
Also noticed the back side of this boat is around just 4.8 inches tall -maybe I have an issue with heavy load this side and not enough clearance from water entering the hull. If I will give it a try I let you know. Thank you for your help indeed... Last minutes thoughts: Maybe I will take the route of scratch-building a new r/c air boats from spare parts I have in my lab (see here) |
No comment!

I've considered building a mono-hull airboat but I just haven't gotten around to it. The 7.4" width is going to be too narrow, no doubt. The length isnt bad though. Along Mikeup's thought, If you came up with another Shockwave hull, connect the two hulls together and use a BIG motor and a BIG battery and really scoot.
BUT, likely its not worth all the effort to convert a mono hull wet-propped boat to air power. A scratchbuild is in order here I think. |
Thanks for the info guys! So better got with scratchbuild route...!
You were very helpful... I will start with this setup here (as today starting our vacation trip and I want a quick setup to take with me for having some fan in tha calm sea! I know I have to waterproof everything from the corrosive salt etc!) But I will gine a scratch build airboat a try in sea water and let you know! Thanks again! ANY IDEA how I can protect the motor from sea salt?! |
I feel like i've let you down and not meaning to do at all, but Cajun of Liberia, LA helped me out a long time ago with advise and he was known for his knowledge. I wish all the best.

Thanks Mike...!
|
Finally I decided and took the scrath-build route... se here my results so far...
|
Sorry, to have given bad advise.

Here's a hint; tapper the bottom edge of body in with sandpaper and the bow too. This will lessen bottom surface some and increase speed .

I'll resign from site!

Except at the stern. Where the bottom meets the stern, the corner should be as sharp as possible to allow the water to release. A rounded corner there will create a vacuum and slow you down.
