I got my Level 1 certification on a PML Matrix on May 16, 2010 at the CRMRC field in St. Albans, Vermont. I used a Cesaroni 4-grain 29mm H118 Classic motor with 5 second delay and a 36" chute.
If you like installing fins, this is the rocket for you as there are a total of 12 (6 canard, 3 upper, and 3 lower). I added an vvionics bay with a Perfect Flight MiniAlt/WD altimeter but elected to use motor eject for this flight. (Keep it simple for certification attempts!) The flight to about 1300 feet was great and recovery was only 400 feet downwind. I really enjoyed building this rocket. This is the first time I used West System 105/205 epoxy and fillers and I love the versatility and strength of it.
