Last I heard/read here in the states, it is illegal to apply guidance systems on rockets.
Vaguely recall a case where someone had used weight on the aft of a rocket fin (on a pivot) to keep the trajectory of the rocket vertical in flight. (see second illustration)
Since this is not a comprehensive guidance system, but more a stabilizing system would it be considered legal?
Posted also is an idea for a re-usable PJ rocket. CG needs work, the thrust over time is almost opposite of a conventional rocket as the available thrust to weight ratio would be greater at the end of the flight compared to the beginning.
Be a little tricky to approx. altitude vs. fuel load, but some static testing could help establish the parameters.
Would be an interesting control line flyer, rather large tool for a body piercing.
