George I flew mine for a year and a half. I popped the firewall out on about my 6th solo flight. The firewall was a weak 3-ply and I put a good 1/4 or 3/16 firewall back in it with some tri-stock. The only other weakness was the main gear was very soft. I stretched some weedeater string across it just above the axles to keep it from bending so much. I used a TT 46 and a Saito 56 in it and sort of wish I still had it. One of the guys in my club bought it and flys it regularly during the summer.
