Okay, @Dotini has has some outstanding results with his Magnus series
https://www.rocketryforum.com/threads/horizontal-spin-recovery-with-magnus-effect.165378/
and is moving on to more exciting projects.
I am still not buying that Magnus effect provides useful upward lift for a falling rocket.
i propose a test bed, hoping for input from the Magnus Master, @Dotini himself, @Rktman , @mooffle , @boatgeek , and anyone else that want to chime in.
build two fin cans.
both 6 tube fins, one with clockwise cutouts and one normal.
one 34 inch long rocket body with a side port just behind the nose cone.
add weight to the fin can of the cutout fin can to match the intact fin can.
both models should Back Slide, but only the cutout one should spin.
time and observe the flights.
the only unaccounted for variable will be drag, I think it may be different although I am not sure which will be draggy-er, I am guessing the cutout fin can.
I may add an altimeter bay up front, to see if they are reading different altitudes, but that may turn them from BackSliders into LawnDarters, so I may try it with a dummy weight before I risk my new AltimeterTwo.
any thoughts?
