April 15th, 2017 Tripoli Central California High Power Rocket Launch Helm, CA My Madcow Level-2 Rocket launched on a small J reloadable motor.. Aerotech RMS 38/720 J500G-14A (Used an Aeropack 38-54 Motor Adapter) Some interesting things happened at Apogee and are detailed in the video... I noticed that I have a typo in the video at the beginning of the launch sequence it says "J500W" .. that is wrong, I should say J500G.
