Rockets that can be test-fired or flown at SARA:

Model flight vehicles powered by ¼ and ½ A Class rocket motors (0 to 1.25 Newton-seconds), and A to M Class rocket motors (1.25 to 10,240 Newton-seconds) Total Impulse range, i.e. Model Rockets [Civil Aviation Authority (CAA) classification = Small Rockets up to 160 Newton-seconds Total Impulse] and High Power Rockets (CAA classification = Small Rockets exceeding 160 Newton-seconds and up to 10,240 Newton-seconds Total Impulse).

Large Rockets (CAA classification = flight vehicles powered by a rocket motor or combination of rocket motors exceeding 10,240 Newton-seconds Total Impulse). Large Rockets shall only be flown under separate special Permission(s) and NOTAM(s) issued after application to the CAA, and in full compliance with the UKRA Large Rocket Scheme (which is also endorsed and supported by the British Model Flying Association.

Notes on buying commercial rocket motors:

Only purchase those motors on the “IRW 2010 Approved Motor List”, which is in force until further notice, and as per the “Motors” section (2.2 to 2.4) of the United Kingdom Rocketry Association (UKRA) Safety Code.

The list referred to identifies motors that are legal for sale and use in the UK, i.e. Health & Safety Executive classified, and CE marked where appropriate. The motors on this list therefore may be sold and flown in the UK, under British Model Flying Association (BMFA) insurance, subject to the flyer having the appropriate level of UKRA certification (Level 1, 2 & 3) where necessary, and valid Explosives Licence and RCA as required by law, depending on the motor or motors in question. If you do not have a copy of this List, one can be provided. If you have a question about a motor not on this list please contact SARA, or contact the UKRA Safety & Technical Committee.

Experimental engines:

UKRA also has a scheme to allow the flight of experimental or homebuilt hybrid or liquid engines but not homemade solid motors as they are dangerous and illegal in the U.K. Contact the UKRA Safety & Technical Committee for advice.
