Fig 1 Notice the crank assembly is in front of the ronny bracket. Challenger 101 site gives a few ideas of how to install this. I choose the forward mount because it will be esier to reach and control while in a landing configuration. As I don't expect this plane will ever be used for instuction,I will always be in the front as PIC. I temp installed the ronny bracket to make sure I would have max backward movent of the flapperon crank. Tomorrow I'll adjust and rivet the actuating tubes.
