Your plane has a balance point. The wheels are set so it will rest on all three wheels when proerly balanced. If you re-balance it so it does NOT sit on those three wheels, it isn't balanced anymore, is it?
What's worse is that by re-balancing so it sits on it's tail would mean adding tail weight - which means a tail-heavy airplane - which means you'll be bringing it home in a trash bag. [

Huh? Let me see if I understand...when converting to a taildragger, I want the plane to balance on the mains, correct? And the mains need to be positioned roughly near the leading edge of the wing as to avoid nose-overs.
