Thanks Howard, and thanks for your help and time walking me through the cert flight and signing off on the paperwork. The L1 cert flight was a Nuke Pro Maxx on an AT H73J-M with 18 oz of weight in the payload bay to keep the altitude down. I don't think it hit 2000 ft, which is what I wanted. The parachute deployed but didn't unfurl. But it landed in the soft sod, so no damage. Aside from my first high power, Katy launched her first F motor - her Screamin (not)Green Meanie on an AT F32-6T. It FLEW off the launch pad and went a lot higher than my cert flight. We also had our first core sample. Katy's Mean Machine split at the connection point at ejection. The bottom half became (according to Jim F.) a fence post! Luckily no damage. Pictures are in the gallery.
