My second edition kit was missing some plywood for the motor box and landing gear mount. It's been awhile since I built it but I recall some other minor issues with parts from the first edition being substituted for the newer parts. Somehow during the wing construction, I ended up with a warped wing and I called a Goldberg tech and he suggested using a spray solution of amonia and water and sand bagging the problem area. This took care of my warp and all is well. Great airplane but watch the amount of paint you use on the cowl and belly pan as the weight can add up quickly.
