Overstable By Design
Anybody still building these? I know it's "old hat", but I built my first prototype a couple years ago with a BT 50 airframe, and it performed quite nicely. Right now I'm in the middle of upscaling that same design on a BT 70 airframe. Sorry, no pics on this yet. I didn't really think about doing a build thread. Some of my approaches to the old "RotaRoc" design vary in a great many ways, which is what impressed the LCO last year in Orangeburg. Basically I simplified the overkill in some places and put a twist on the props that doesn't conform with yesterdays ideas.
I just got said props primed this afternoon, and the rest of the build is about 3/4 done. The rocket is just over 3' tall and the props are 2" x 26". Here a nekkid pic of the prototype.
