I have all the NAR motor files bookmarked, so I can look up average thrust and peak thrust on all the motors I use, as well as have, or may want to buy. This is especially important since I’ve found motor designations to be wildly off for some motors. The worst examples I have are the Aerotech 18/20 reloads I use on my Mars Lander. I decided on the D13 initially, thinking the D24 may have too much kick. Turns out the D24 is really a D15 (average thrust of 14.77N vs. 12.67N for the D13). I’ll try a D24 next flight. The Mars Lander just screams on a D13, by the way.
