Realflight G55 Exclusive Download [better] -
The "Exclusive" version typically simulates an electric power system (EP). The simulation models the voltage sag of lithium-polymer (LiPo) batteries and the diminishing returns of thrust as the flight progresses. This teaches pilots throttle management, distinguishing the G-55 from "unlimited" 3D aerobatic models that have infinite vertical performance.
