starter-torque (fgfs 2.8) is a value specifying the zero RPM torque in lb*ft the starter motor provides. Current default value is 40% of the maximum horsepower value. | |||
starter-rpm (fgfs 2.8) is a value specifying the maximum RPM the unloaded starter motor can achieve. Loads placed on the engine by the propeller and throttle will further limit RPM achieved in practice. Peak starter power is achieved at 1/2 starter-rpm. At 1/2 starter-rpm torque is 1/2 starter-torque. Peak power can be calculated by the standard formula HP=(Torque*RPM)/5252 | |||
