That seems likely. The heavier motor pushed terminal speed past the alarm limit. The heavier rocket will not only have a higher terminal speed, it will take longer to accelerate to terminal speed. It doesn't seem as likely, but it may be that main deployment for the larger motor is happening before the rocket under drogue reaches terminal speed. https://www.rocketryforum.com/threa...y-have-to-morph-into-hpr.146005/#post-1786551 (What kind of tool quotes himself on an internet discussion board) It comes to the same thing though, the heavier motor means higher speed at deployment. EDIT: Got my smallers/largers, heaviers/lighters all tangled up.
