I once had a customer that had two of his own design F3A models. All wood. One model would get about 150 flights and the other would wear out aileron pots in about 30 flights. Long story, but the bottom line was that the only difference between the models was the position of the aileron servos. On model had the servos very close to the end of the wing tube and that was the one that had the short life on the pots. We had to conclude that some harmonics due to the tube was causing the issue. He later moved the location to where the other models’ aileron servos were, and the problem went away…</span></font></p></div>
