This is a great choice of rocket for those who want to step up to the bigger (29mm) engines. Launched once and it flew arrow straight on an E12-4 with a 24 to 29 mm adapter. Recovered with no damage. I made a couple of small modifications to the build: 1. Replaced the paper shock cord mount with a Kevlar cord tied to the motor mount. 2. Added a thrust ring. None included with the kit, instructions say to tape a small strip at the end of the motor but a thrust ring is more convenient to me. Of course, if you use a motor with a lip on the back then you don't need it. Uses the screw on plastic motor retainer system, which I love. Overall, it's beautiful, economical, and a great value. Will upload a picture soon.
