I have mine ready to test fly just as soon as the weather permits. I installed a "Taurus," 3.2 on mine and I mounted the Battery for the ignition, and the ignition unit on each side of the Firewall engine box. I mounted the throttle servo just behind the fuea tank, and every thing else as recomended by the mfg. My balance point is dead on the money with this installation. Now if the weather will just clear up.
