ok so i never have had any servo issues with my 8ight and its a 1st run kit. but other people have and i have torn their servos apart and found broken gears due to hard impact or tray flex. the biggest problem with the tray is the rear battery box it only has one screw to hold it, this causes flex/vibration you can calm it down bye putting an oring under it but all in all that radio tray does have some give to it that will cause a problem if you dont spend the extra time setting up youre servos.
