A Little Help Please
I have a lot of hitec servos (in all sizes) but a lot of the HS 80 and newer HS 81's. I have had at least 3 of them fail for no reason, in a plane. One last fall in my lazy bee, it went hard over (on my elevator) and stuck full down. Luckily my bee' went into the soft snow and was unhurt. That was an HS80. I dont think I have had any problems with the HS81's yet, and will continue to use them.
Sometimes, after the winter storage, I notice some servos slower and jittery than they were before the flying season ended. SOmetimes they just need to be usd a bit before coming back, but sometimes they just get worse and I end up replacing them. I think if a servo was "on the way out" before you packed it away for the winter, the long storage must not help matters. Anyway, I cant say exactly what the problem is, just that it has happened to me more than once. (by the way my storage and our winters here are extrememly dry).
