He could use silk instead of fiberglass. It's a lot lighter. But it's not as strong but it holds, i know from experience. I ripped the gear out of my 33% raven (composite) once and I accidentally used silk instead of fiberglass ( I didnt know any better) but the next hard landing I had hit hard as F**K, but all it did was knock it loose a little, but I still had to grind it all back out so then i used glass, I told my dad it aint coming out again! I was right, the next hard landing i had w\ it was a deadstick, i landed about 15ft too high, the gear tried to come out but all it did was pull the nose w\ it.
