I really am surprised how well these fly.
After flying the Odd'l Rockets Corkscrew and some other extreme Asymmetric Ring Fin designs (Triple Sec and Little Deuce Scoupe Two Stage), wondered how well markedly asymmetric fin placement would work with other geometric shapes other than rings. This is also part of my "research" for a MIRV type rocket with a single booster and three sustainers (tentatively going to be the Cerberus, as the concept and name MIRV Gryphon has already been used) and possible a Medusa (with single booster and 6 sustainers--- although keeping track for recovery purposed may be a nightmare.)
In any case, here are the Test Rockets. All of these had perfectly straight trajectories with no weather cocking (although winds were minimal). All of them did "corkscrew" or roll around their long axes, but it did not affect the flight path. The last one, the "Square-Off" had an interesting descent. Even though it was a streamer rocket, with a normal internal shock cord attachment, the rocket recovered in a horizontal attitude, in fact it was almost a glide recovery. All of these were BT-5 with 1/32 balsa fins (some of them were papered ----the papering made it easier to get the shape right during the build.)
