After many flights on my SM F15, I started to have probs with the elevator clevises. While the plane was apart I went ahead and replaced the servo arm with the new JR plastic arm with the metal ring around the screw. Its a smidge thicker than the average arm.

When I tackled the clevis issue, I went with the Dubro 4-40 locking clevises on the servo end and a swivel link on the control horn end. I switched to the Hangar 9 Titanium pushrods too. I like the Dubros because they are self tapping and the pushrods come with one end reverse threaded so I cannot come loose in flight. When I put the clevis on, the servo arm was just a tad too thick and I couldnt get the locking clip to go on the pin. I tried and tried and finally gave up. I drilled a 1/16" hole through the plastic part of the clevis and safety wired it together so now it cant come apart at all.

Before I fly it like that, I would like to see if anyone sees a potential problem here.

Thanks,
Mike
