RE: U can do CG
I had a 60 U-can-do. Total flight time was in the neighborhood of 1.5 seconds. Ihad the ailerons reversed and what a pile of sticks I had to pick up. Several of the guys at the field had them in varing sizes and Ireally looked forward to getting mine airborne. The GG was dead on, the ailerons howerverwere not.
Double check everything before flyng, and have someone else do the second check. "MOM, how come I have to learn everything the hard way"? A queston I ask some 60 years back. Still havent' got it right.
