I can not understand balancing a high wing plane upside down...Can sombody explain this to me. I understand how it works balanceing a low wing rite side up if it has enough dihedral and you do it from the wing tips..But I just cant see how you could balance a high wing upside down..
Let's turn it around a little bit. How do you balance a high wing plane right side up?

Are you going to use an incidence meter on the wing to see if it's level when you have the plane hanging? Another type level of some kind on a different reference line you can determine will be close someplace else? If not, how are you going to know if the plane is hanging with the nose or tail low? If either way, it's NOT hung/being supported on it's CG.....

If upside down (hopefully you're doing this close to a table or the ground?) it's going to fall one way or the other until you get it supported under the CG...

Either way works - you just need to remember to use the level on a reference line when doing it right side up. That's an added complication many don't want to get into.
