  1. James

    Used with my Modified Crossfire ISX (along with an E launch controller and launch pad, obviously) and it went crazy high. I don’t have an altimeter on that one right now but it was well out of sight for a while. I was able to recover thanks to the large launch site.

    I will also be launching a new Mean machine, too and I’m really excited for that! I’ll launch that one on these and on some aerotech F motors if I get ambitious.
