Well I never fly my airplanes with gyro aids and I can tell you they all fly rock solid. I understand the use of extra stabilization methods by some fellow modellers - most of them rookies- but still it all have to do with piloting skills or poor aircraft designs. The buffeting that you are mentioning is happening either from poor aerodynamics, or exceeding flying speeds, or even from windy (gusty) weather. My choice is to fly my own planes on my own. If I leave the pleasure of using the master 4 controls of my models to some dumb electronic stabilators then it will come the time to leave the hobby and start R/C "Gyrolling" - building UAV's that will fly themselves 100% and I will have the time to watch them fly , who knows maybe filming them while they 'll fly...I'll have plenty of time to do that since I will practicaly won't fly them!!!
