Ok, so I set out to balance my GP Ultimate Bipe tonight. Pulled out my trusty (it worked for my Avistar) GP C.G. Machine, only I can't use it since the upper wing gets in the way. So using the unscientific (read $0.00) method of holding it, it balances at the 2-3/8" recommended point, but the tail drops ever so slightly. Move my fingers back 1/4" and it seems perfect. Should I worry about this or mount the battery where it is and go flying? (When the weather warms up of course.)

Also, I haven't painted my cabane, gear, and cowl yet. Will the paint add enough weight to make a difference?
