You guys using 13mm motors with adapters are cheating.
Stick with the 18mm motor, as Vern and the Good Lord intended.
I flew mine on a 1/2A6-2 engine. Too keep it from sliding too far forward and charring the tube and fins, I stuck a bent paper clip into the front of the casing. This kept the rear of the motor flush with the rear of the tube.
I flew mine (#0123) on the 4th of July at the same time as Tater Schuld (#0474). Tater flew his on an A8-3. Both of them whizzed off the pad and disappeared. Fortunately, my nephew spotted mine laying on the ground about 60 feet from the pad. Tater's landed about 150 feet away and just missed the gravel road.
The hook did its job by holding the motor in place. Unfortunately, one of the fins tore loose on landing. It should be easy to repair.
The fins had only a little charring, much less than Tater's. I don't know how much difference was caused by the smaller engine and how much by the paper clip standoff, but whatever it was, it helped.
There was only a small amount of smoke haze down the sides of the tube near the exhaust holes. Hopefully I can wipe it off without damaging the decal.
Now that this Golden Scout has flown in the Sky of Gold event, it will be retired and proudly displayed in a place of honor in my newly remodeled underground laboratory.
