Northern Colorado Rocketry launches on the first Saturday of every month. In the winter and spring, we launch on the south side of the Pawnee National Grassland; in the summer and fall, we launch on the north side. The north launch site has a much better altitude waiver and very few fences, so it is the preferred site; however, when the ground is soft we risk damaging the environment: the south launch site is paved everywhere - even where we launch the rockets because it is the roof of a retired Atlas missile silo.
The March 1st launch was on a beautiful day. Greg and family went up for a day of launching and I drove up as well. Greg certified Level 1 on his PML Black Brant - a nice kit and excellently built / finished by Greg. I forgot my Tripoli papers, so I couldn't attempt to certify, but I could still fly practice flights.
I flew my Talon 2 on an H128. The Talon 2 is very light so it really popped quickly off the pad. The ideal delay, according to RockSim, would have been 8 seconds but the H128 does 6 or 10 second delays: I went with the 10 second delay so deployment was a couple seconds after apogee. Chute opened fine and the Talon 2 drifted out of site during decent because I used a larger chute than normal to ensure a soft landing. Apparently, the large chute didn't help with the landing because the rocket broke - like completely broke:
Next launch in 34 days - I better get building...
