Thought you guys might like to see how I crammed my ZDZ 40 into my GP Super Stearman. Note throttle and linkage setup, custom-built pitts muffler and engine mounts, close pivot point on aileron drag links. Plane has all digital high-torque JR's. Radio setup includes dual elevator servos, differential ailerons, switchable and rotary dial flaps, idle down/throttle cut, dual rates, and exponential. I also removed original tank and installed a smaller ten-ounce tank centered over the CG. This allows at least 13 minutes of flight time on gasoline. I'll post other details later if anyone is interested.
