Was just wondering if anyone has been having trouble with servos I just purchased one this last month got four flights on it and the left aileron servo started twitching when moved one direction, luckily it happened on the ground before I flew it. Get it replaced and then the other side does same thing while flying and it crashes. I know this sort of thing can happen but just wondering about the quality of tech one servos, it's just weird to me that two servos failed.
