I was reading through the NARTS motor listing in the back of sport rocketry recently and it said that Aerotech's I600R has a total impulse of 597 total n-sec., which is equivalent to a 53% I motor. However, on Rocksim and OpenRocket, and the actual motor package itself, it claims it to have a total impulse of 640 n-sec., which makes it a 100% I motor . Can anybody please tell me the real impulse?
