Our normal pressure molded production wings are 92 to 95 lb with lots of primer
ready for fine sand and final paint. The Carbon wings I made for my STD 300
hp+ weigh 85lbs with final paint and are much stronger than normal.Did you
build your wings in cold or real hot weather? That can add a few pounds.
How true is the contour? This really effects the performance.
I tried to sell you a set of my wings!
