SimpleFlows v22 but midified to use helicopter rotars. Preset 1 = activates throttle. Preset 2 = activates collective. Preset 3 = activates cyclic control. Firet set throttle to 100% and activate preset 1. Once engines spin up deselect preset 1 and reset throttle to 0. Then select preset 2 and 3. For vtol or stol engine angles fly like a helo being carefull with roll and yaw. Once suffecient speed and altittude is gained slowly transition the vtol slider to the top for forward flight. Once engine angles are forward disable preset 3 for normal airplane controls. Again, I did not make the model, only modified the engines and controls to include helo controls.
