Any suggestions for a VERY cheap >home-buildable helicopter? There is good reason why you havent seen such things. Theyre too complex and too difficult to fly. Ive heard of analyses showing that helicopters are inherently unstable. They can be made stable, of course, but that takes extra feedback and controls (weight, weight and more weight). Frankly, a Robinson R22 is about as light a helicopter as Id want to fly. Now if youre talking about gyrocopters, thats a different matter entirely...
