Premium Members Benjamin Treplin Posted August 8, 2004 Premium Members Report Share Posted August 8, 2004 In any case, I'm still curious about the flex question. -------------------- Anthony Hardwick Venice, CA USA Any advice here, because i would like to put one of these pins in my Pro arm.It seems like an obvious thing to have, and these pins are available even cheaper from McMaster-Carr. (I never knew the correct size to get though, so i have yet to buy one.) I still do not understand why GPI does not offer these pins, nor have they done tests with these pins to determine if flex is an issue or not. rich -------------------- Richard J Cottrell Philadelphia, PA Hi all, after having the aircraft pin in my PRO arm for a few months now I like to give a little review. There are differences between the original PRO pin and the Aircraft pin. It is hollow but IMHO this doesn?t have any effect. It doesn?t lock the socket block to the arm like the Pro bolt with its nuts. I?m not sure if this has any effect. The original PRO pin is exactly 9,5 mm / 3/8 inch, this is 0,05 mm thicker than my aircraft pin. This has an effect. This is with in production tolerances of Avibank. See link: Avibank Due to its smaller diameter and free sliding in its guide the aircraft pin causes a little horizontal play and a vertical play in the socket block section when not under load. Under load I experienced a little flexing, very subtle. The arm is bending a bit before it is actually starting to move down. This is only noticeable when doing very small and very slow moves. In addition, and this is really annoying, the arm starts clicking (or better the pin in its guide), especially when resting your arm on the lower arm section. It is not as loud as when the screws of the arm come loose from transportation in the car and it is a higher sound. Finally, I?m not sure if the upper hole that has no steal guide is wearing out from an extended use of the aircraft pin. In the future I?m using the aircraft pin only when I?m actually forced to switch sides or it is foreseeable it could happen several times a day. I hope this answers your question, Anthony and Rich. Are there other Ops with experience on this modification? Benjamin Quote Link to comment Share on other sites More sharing options...
