Put the motor mount together. 24mm, I figure if I conclude the E12 won’t lift it, there are 24mm composite options, like the E30. And if I crash it, I might be unhappy, but I can always build another. Since it might fly with an E30, I used a heavy wall BT-50 and added a third centering ring for a little extra strength, which is glued inside the body tube, used a long skewer to get the epoxy in the right place as I installed the mount. Also used the Estes Pro Series 24mm motor retention and a kevlar leader.
"You know, it, uh, won’t fly unless somebody pushes the button." From the movie October Sky.
