Nutball C of G


Junior Member
Just built my Nutball seems fine except for two issues. The centre of gravity can only be made correct by 60 grams of nose weight! The only thing I can think of (as I followed the plans) is I put a fine waterproofing bead of hot glue - wiped off on the perimeter of the foam. I also wiped hot glue on the elevator hinge but despite wiping it off the hinge is stiff and down elevator does not work well. Push rod bends.

Battery 3 cell LiPo velcroed up front - Blue Wonder motor.

Great show and I am starting again after 35 years away from the hobby. lots of great technical innovations - I love your attitude at Flite Test and hope you prosper.

I would appreciate any advice from forum members
