What a huge chute it is. How heavy is the Principality II?
About 2.6 pounds. The 8' parachute is for Phoenix though, which weighs about 15 pounds with motor.

The small rubber bands that he suggested to wrap around the Kevlar should do it.Phoenix made its first flight with the new parachute last weekend on a J415W. It was not entirely successful, with the pilot chute's shroud lines tangling with the main parachute's shroud lines and preventing the main from opening completely.
One of the TAP members I am working with for my level 3 noted the problem seemed to be that the bag let go too quickly and everything kind of dumped out of the tube together, enabling the tangle, and gave me some pointers for keeping the bag closed until it's away from the rocket and the pilot chute has a chance to actually start pulling on it. I will be spending some time over this month until the next launch practicing and testing the packing method he showed me.
Pictures and flight data from the Raven3 will be forthcoming later today.
The end of the tube turned out good. The bottom of the fin I missed. Still it held up well for a 15 pound rocket hitting the ground.

Good job. On the fin repair will you run another fillet? I have to fix my Nike-X.

About how much time does it take to do this step? This looks very good John.I practiced tying up the main parachute for bag deployment. After the mishap last month, my goal this month is to get a good bag deployment from this rocket. I will be flying with MDRA this weekend at the Sod Farm with a J315R motor. If this goes well, I am hoping to fly at Higgs on a K540M next month.

The Estes Solo picture looks like an Advertisement for Estes.
Outstanding John, what the two small "V"areas in the graph? One is at the top and the other is near the bottom right.

I gives the rocket a short boost you mean? That is awesome.Those should be when the rocket is jarred by the apogee and main deployment charges.

Got it. ThanksHmm, since they are downward-pointing spikes, it's more likely a little bit of ejection gas is getting into the electronics bay and causing a tiny pressure spike that makes it think it's lower than it is for a brief moment.

Congrats to you John on a great flight. Wish I was there. 472 feet shy of one mile is impressive. Is about 120 pounds of thrust output correct that I calculated? How much of a Window did they give all of you?Mostly successful flight to 4728 feet and 520 mph. The thing is, the clouds were much lower than I thought and the rocket flew past the cloud ceiling and no one saw it again until it was already back on the ground. I am not sure if the parachute opened fully or not, but if I had to guess I would say probably not.
Regardless, the rocket is undamaged and accomplished the objective of defeating the K540M that destroyed its predecessor. This concludes my level 3 test program. I plan to premier the Seraphim (my level 3 rocket) on January 8-9 at the Higgs Farm for a shakedown flight on a K1000T.
