Tube fins and launch lug placement. If the launch rod does not clear the nose cone, rotate the cone a half turn. Motor retention: apply tape to the motor/motor tube joint. Launch Lug e 2" long, 1/8" diameter launch lug is glued at the tube fin, Segment 1 tube joint. Be sure your launch lug placement allows clear passage for the launch rod. If the nose cone lip overhang is in the way, simply turn the cone. e nose cone shape has high and low sides to allow clearance with a half turn. Motor Retention A simple wrap of tape around the exposed engine mount tube and engine is sufficient to hold it in place during boost and ejection. e High Roller has been launched with B6-4 and C6-5 en- gines. All flights have been very stable. I hope one day to see a drag race launch alongside the Estes Pot Shot.
