Do this update to the C441 aircraft.cfg: [GeneralEngineData] engine_type = 5 Engine.0 = -3.5, -5.0, -0.4 Engine.1 = -3.5, 5.0, -0.4 fuel_flow_scalar = 0.88 min_throttle_limit = -0.26

I had the same issue with not being able to start the engines (with APU/bleed); however, they start just fine with the GPU.
