Your settings in the aircraft flight parameters denote the preset speeds. First press of the throttle manager key puts you in speed adjust mode, starts at your speed and the forward and back keys change the speed setting by one knot. The second press of the throttle manager key puts you in speed presets mode, the forward and back keys change the presets. Your version takes a long time to set off from zero.
The next version controls the power more effectively and sets off better. The IF throttle manager works on a three second cycle and since it is designed to work with any plane, it must learn the power and inertia for each aircraft with a custom AI system.
