The only fixed rules here are that ALL rockets (apart from
Aquajets) must have a
recovery system - parachute, streamer or other drag devices, or must
employ a featherweight, tumble or glide recovery, and be properly
constructed of suitable materials. (No metal body tubes and nose cones). Aquajets generally use tumble recovery.
All types of model and high power rockets in the power range from 1/2 A power up to K power may be flown at the Rocket Weekend, subject to the sanction of the Range Safety Officer (RSO), who will rule on all launches at the Rocket Weekend.
