I have recently joined Tripoli and intend to fly both G and H motors. I willl use the Drago for my Level 1 flight later this month at a club launch. In the mean time I intend to fly G motors including G80 and G 125. The Tripoli guide lines are upto G = 30ft, H = 50ft. Actully I would be more comfortble with the 50ft+ with the G motors, that is why I was considering extending the cable on the Estes E controller.
G125 is an L1 motor in the US, FWIW.
OR > 80 avg.
Single motor total impulse is but one criteria that defines the line to high power. Average thrust greater than 80N is another. This handy little graph shows them all. View attachment 293480

Goto V. The Distance Tables. Goto minimum safe distance commercial launches.
The minimum separation distance for an A-G* motor is 30' except for the * which means A-G motors exceeding 80 N average thrust are to be flown at the H minimum separation distance because they are considered high power motor and also require L1 or higher user certification.
The minimum separation distance of a single commercial H, I or J motor is 100'. For a complex, either clustered or staged, rocket using multiple commercial motors with a total installed impulse between 160 Ns to 1280 Ns, the minimum separation distance is increased to 200'. (Straight from NFPA 1127, the basis of the TRA Commercial High Power Safety Code.)
