Easier to ask when I wasn't?
To hand prop, it is better to be behind the prop with one hand on the cowl and stepping back as you pull it thru.
I always hand started my gyros from the side in front of the prop (being pusher) with my left hand with a firm grip on the motor to help balance and push myself away ..... but I always make sure I know EXACTLY where the throttle is set.... and either chock the wheels or tether the back so it cant roll away.... I watched a guy with a VW Bensen hand start and the machine ran across the airstrip and into some trees.... the front rotor (tied) dug in and bent naturally, then the back blade came down and wrecked itself and the wood prop
Over here, it is against the regs to start or hand prop any aircraft without someone who knows how to stop the motor etc.... it was unavoidable for me tho sometimes.... when with friends and other gyro people it is no issue, but when I landed somewhere with no one around, I just had to be careful.
Waddles from ASRA lost part of a finger and damaged his hand on the prop of his RafTor
It can happen.... happen fast and props don't say sorry
