I have a modified LOC Black Brandt (about 2.5ft shorter) weighs 7.2lbs with
everything minus motor & casings. If having a 5:1 ratio is minimum, when I add
2.5lbs using a J135 I have 9.7lbs total lift off weight. When I calculate the
ratio on the average thrust verses I get 3.6: 1 and with the peak thrust 6.3:
1. So, do we calculate the ratio for liftoff on the average or peak thrust?
Would this be a safe motor for this rocket weight?
Also, Rod Lovely, which K motor were you recommending after its maiden flight?
Thanks,
Dale

AeroTech order is going in tomorrow afternoon. If you need motors for
DA or beyond please order by 3pm. Sorry I meant to make an announcement at the
launch. Will there
be a Nike drag race? Do we need K2050’s?
