Hi Tim
I added a speed brake and a lot of carbon fiber, mine weighs 13.25 dry. I fly at 5200 ft and we need a lot of drag to get the planes to slow down. I also made the flaps bigger than you showed on the plans. The plane fly’s great at that weight smooth take offs and landings. Thanks Again George
