New "true" engine sound with RPM-dependent sound, turns off on crashes with prop / engine damage like it should. Designed as an attempt to simulate the difficulties of flying with such a large rotating mass (rotary radial). UAC1 planes are designed for Multimode (two Interlink controllers on one computer, or other controller with simulator cable port) Ultimate Aerial Combat (WWI).

Dual rates switch = smoke + toggle rudder coordination, retracts switch controls smoke color (smoke on = autoruddder off.) 3-pos switch: down = machine gun, up = rockets. 2 special weapons on the flaps knob: cannons and tractor pulse rockets.
