ground clearance
How little clearance is too little? So I put a 55AX on my 40 size trainer and the prop is only about an inch maybe inch and a half from ground. Don't know if I can grease her in every time. And I'll probably be breaking props. What's a good minimum to shoot for. I have a 12x6 on there now.

RE: ground clearance
Hi,
Assuming your trainer has "trike" undercarriage slide the nose wheel leg as far down as possible ensuring there is still sufficent in the top mount and bend the rear undercart in to lift and compensate for the higher nose leg. This way you should have sufficient clearance. When viewed from the side the model should have very slight positive incidence when you have finished bending and extending. If the clearance is still insufficient try a three blade prop.
Cheers,
Colin
