.30 Four Stroke Scratch build
I just finished building this air boat, it's my first nitro air boat build, no plans or measurements used or taken after it was built, I have a magnum .30 four stroke swinging a 10x6 master airscrew prop, hull is bass and balsa coated with minwax poly-shades stain and poly in one step...I used engine mounts and the mounting plate(modified for the .30) from the aquacraft airforce which you can buy from towers parts store, futaba fasst radio gear water proofed, 4oz. tank, runs great, on grass, snow, and ice. It will climb at least a 45 degree slope and today blew over at around 3/4 throttle on snow so I changed the thrust angle a bit to try it again tomorrow, I can't even open this thing up on the frozen pond or snow cause it's crazy fast and starts getting really light and catching air...still want to add some more sheeting on the front and extend the nose up into a brush guard to help when entering the water and hitting slopes, I also need to add some foam for floatation in case it flips in the water once the pond unfreezes...heres pics...

RE: .30 Four Stroke Scratch build
yeah I'm gonna add more sheeting, just wanted to get it operational while the snows still on the ground and now we are supposed to get another 12+ inches here tomorrow and wednesday on top of the probably 20 inches we got friday night into saturday...it's great for snow boating
