This is a scratch built air boat from ply and balsa with a McDonald's Happy Meal Shrek. 2.4gHz, and lipo battery, still trialing different props. The fan cage is a cut down squirrel proof bird feeder !
After my initial trail and failure to use a 'pulling' type propeller the wrong way round to push the boat forward, i have simply reversed the propeller, so it no faces forward. The prop now faces the way it was designed to, and should give allot more thrust, but I still have a few more props coming on the post to see what works best.
