I was flying my corsair yesterday at the local park. During the last flight my contact popped out of my eye and landed on my cheek!
I was trying to be still and quickly get the plane on the ground which ended up with the plane taking a hard landing (I belly land the corsair). My contact promptly fell off my cheek, bounced off my arm and landed in the grass. Luckily I was able to find the contact so that saved $160!!!! The corsair wasn't quite so lucky, the landing broke the servo arm off the aileron.
Easy fix! However when I got home I realized that this aileron servo has a larger diameter shaft and finer threads then all of the spare servo arms I had. Obviously there are different servo output shafts, but all the servos I have are small like the PZ servo. The question is how to I locate the correct servo arm? Are there names for each type of servo output shaft?
