Hand crank
I was worried about the thought of hand cranking too . But I read in the manual that the Bosch magneto used on the compressor has an inbuilt anti kick back device . Its called IMPULSE COUPLING . The initial spark is delayed until TDC has passed . A few old hand started aircraft have a similar thing . I think a starter motor is the sensible way to do it .
One thing I was told about the XAH Waukesha in the compressor is , the exhaust is a straight out vertical tube with a 6" section squeezed down to create some back pressure , without any back pressure they burn out exhaust valves in quick time .
