At the TNT contest I wanted to fly RES for the first time in a contest and was in a rush to leave after two rounds because family needed me. My goal was a single piece takoff and landing. I'm new to winches, in a rush flying a plane I'm new to. So I did the weenie bent arm hold on my newly acquired Topaz and the stab grazed my head on launch. It went up about 50 feet, I left the pedal alone and tried to glide it down. Somehow it leveled off before begining to plow Southfork Ranch, and the only damage was a destroyed fin and busted out mount portion of the stab. So much for single piece takeoff.

Photos show that I did not rebuild the fin post with uni-carbon over the balsa per original, but instead used carbon mat to add toughness but very little strength. The ribs were reused. It all went together smoothly. It has now been flown and there is no difference I can tell but perhaps a little heavier in the tail.

Small details were added, such as a fairing across the top of the fin post instead of the gap the factory Topaz has (yuck).
