Nice looking gyro! I checked out the video too. When mine gets too beat up, I might try that one. Here's one more beginner type question that I was wondering about. I've noticed that alot of gyros have a considerable amount of downthrust on the engine. My Kombat Kopter has no downthrust and has the tendency to pitch up with added throttle. Would the addition of downthrust help this problem? Also, I remeber seeing a picture that shows a guidline for gyrocopter dimesions. It had all the angles for the mast and the downthrust. It also had the dimensions of the rotor compared to the size of the gyro. Does anyone have this?
