Hello all. I had the chance to go flying over the weekend. I got 5 batteries in on my Tarot 450 before my heli decided to go into a tail spin on the sixth battery. During inspection, i thought it might be the tail servo went bad before the crash, of course. It turn out to be a ball linkage on the tail slider. I like to know what device or method you can use to test servos to see if they are going bad? It wasn't the servo that cause my crash this time but it did cross my mind about servo testing. Any suggestion is appreciated, Thank you in advance.
