What's the radius of the trim wheel at the handle position?
I would say the radius at the handle is between 10 and 15cm. So, that would give a force required to manually crank - WITHOUT any air loads - of 2,5 to 7 kg for a 10 cm radius and 1,67 to 4,67 kg for a 15 cm radius wheel.
I am fairly sure that the radius at the handle is closer to 10 cm than to 15 cm.
