what size and pitch ratio is the prop
Sorry, I mean dog drive
Oh, now I see. Yes, Dog drive already installed on the shaft and fits perfectly with prop that comes with it. There's nut with plastic threadlock provided, so prop will fix good.

How do I hold the propeller on the shaft?
Just put it on the shaft and fix with nut provided. The nut has plastic threadlock so it's pretty reliable.
Does it includes the dogbone?
Dogbone? I don't think it's necessary here. I mean I know what is it, I use it in rc-car... Kit includes one prop, one nut with plastick threadlock for fix prop and the shaft.
