Same basic design, just made a few changes to ease the process of flying. The tail rotor now works to compensate for cyclic controls along with a gyro for some limitation to prevent the helicopter from flipping. I also noticed that in forward flight the helicopter tends to flutter a bit, and that just easing the collective pitch back down will tend to give for smoother flight behavior. I've also found that anything beyond 50% throttle is asking for trouble, as I've been able to tear the tail rotor apart as low as 57% throttle with violent control movement. Basic setup I takeoff with is about 55% throttle (just for takeoff) with the VTOL slider about 75% of the way up from neutral. Hope it feels better, also tried to get the weight and balance closer to where the Center of Gravity should be on the rotor mast, and added some more detail.(sorry about that not being the case with the last version).
