RP 100% is a difficult number to acheve and While I cannot claim that with any accuracy as its difficult to know 'But' I do believe my little procedure I outlined to help reliability to a considerable degree.

Now I have had many destroyed and stripped servos from flutter especially in pylon racing but that is totally unrelated to electronics. Servos are often accused of being causes of that but that is not really the case and it is entirely an outside causes (in my opinion).

Another cause of servo failure also totally outside the electronics factors and that is simple 'Hanger Rash' such as banging control surfaces on doors jams etc.
