May I suggest that no hand propping as we have lost 3 planes on our field over the years due to this. As for aerobatic maybe make the rule only with instructor and limited maneuvers as this will make much better pilots. After all this is part of the plane’s purpose.
Bruce,
We decided to make electric start, ADS-B, and hard wired radios/intercom requirements for whichever airplane we buy. Unfortunately this rules out most Champs and drives the prices up a bit but we figured it was worth it for members and better for the club.
