I have been tempted to change the control system to that of rods instead of cables but keep reminding myself that small changes made tend to add significantly to the build time. With this in mind I am sticking to the cable system. The aileron arm is as per the plans. Drawn onto the .035" 4130N and then cut with the hand grinder and cut off wheel. 3/8" hole drilled for the bushing then notched with flap wheel to fit over the tubing.
