balancing the flying lawn mower - PLEASE HELP!!!
Hi, I am working on a flying lawnmower from tennessee model products. It will be powered by a thundertiger pro .91. the book lists the cg between 8 and 10 " back from the leading edge. Do you balance it right side up or inverted? right side up seems to take almost 10 oz of lead to get it to balance at 10 ", but inverted only takes about an ounce or two. Both ways seem like it wants to fall off the cg stand if it is bumped slightly in either direction.
Thanks for your time

the flying lawnmower is top heavy as you can tell from your balance, try to lower your plane on the cg stand so that the wing is lower than where you have it now.
