I don't use plastic or nylon clevises on anything powered. I have had them break, and also the vibration strips them off the metal rod. I only use metal. Also, the dubro quick lock connector with the screw is bad on power. I might use it on a throttle now and then, but there are 2 ways it can come loose. The bolt can loosen or the rod slip, and the snap on holder can come loose and it can fall out of the arm. They are kind of scarey. I wouldn't use them on a power plane period. I learned the hard way and lost a plane from a plastic clevis letting go. Hope you learn by that too so it doesn't cost you a plane.
