Despite the small engine it went up fast to a fairly decent altitude; the streamer detached at deployment, but it fell sideways to the ground and was only very slightly damaged. I had hoped to fly it with a B6-6 also but decided not to go on with that, given the visibly poor condition of the Kevlar shock cord leader on that rocket. I could repair the defects, but I think I'll retire this one and build another, more authentic-looking clone instead.
