Is your test pilot skilled in such experimental odd roc flights? It looks cool up there skywriting... not so cool if you were in the line of fire though I bet.
You could always retrofit some rear tubes... that would make it fly straight. It's the perfect design for that.
Please excuse my amateur photo hack..

Thanks, yes I am contemplating rear features I can add to this model to make it more stable. I also maybe should have recessed the motor and put some slots in the sides so that I could use GDS to help stabilize. I am probably beyond my amateur rocketry aerodynamic capabilities at this point...
My co-pilot was warned that this one was the most likely to be unstable but the rocket took an inconvenient turn and wound up between us on the ground so that was more disconcerting than other unsuccessful test flights... Maybe I need to bring goggles and helmets if I will test this one again...
It will look good as a shelf display in the meantime.
