Now it's on to the radio box set up. The servo blocks for the Futaba 5301 1/4 scale steering servo are already positioned and epoxied in place. The bellcrank system I use for the throttle pushrods is built up and being positioned for gluing in the mount pads it sits on. This is another part of the build that absolute accuracy is a must to insure both throttles will function with mirror image consistency. I probably spend more time here than any other part of a twin build.
