As I said... its been done.

I planned it out a bit better... and I mounted the rocket to fire straight out the tail. (and had the on-board lighter.)

The low power test went well. Lit it off and had an anemicly powered model gain 150 ft altitude in nothing flat. (should have been a warning that the rocket thrust line was wrong for the bigger motor.)

The high power... did a figure-9... with the lower part of the 9 underground.

Others have done it and had better results.
