Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}19/KT. 25.1.33. X4027. X5370. X7370. SERVO DRIVING PINS. We proved out on the last 10,000 miles on Peregrine that there was no detriment in having .010" diametral clearance on the servo driving pins. The advantage of this is that it reduces the tendency for these pins to bind. We recommend that it should be adopted on all servos. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
