Today was mostly a casual flying day as we are still working on the larger rockets. Since we weren't able to attend the NSWRA launch a month ago and the last launch was cancelled due to poor weather we took this opportunity to get the kids out of the house and fly some of the older rockets. We also wanted to fly the HD camera again. We had to buy a new one, after the last one was destroyed during a big pyro rocket crash in Williams earlier this year. We also wanted to continue getting more flights done with the Servo Timer II to get more data on how it performs.

There was virtually no wind, but the sky was completely overcast. The main problem with flying in cloudy conditions are the poor video results you get from both the ground and from the air. What didn't help was forgetting to set the white balance correctly on the hand held cam.

By 10:30am we had flown 6 flights all together with 3 of them using water and 3 using foam. On the first flight the small parachute tangled a little, but still opened up well above ground. The rocket hit the ground nose first though and buckled the aero-shell but the rest of the mechanism was fine. We popped the aeroshell back out and set the rocket up again, but replaced the parachute with a larger one.

The other water only flights went well with the parachute deployment right at apogee, and good video was also captured.

The first foam flight was quite slow, but had no problems in getting up to full altitude. We reduced the amount of water in the rocket from 1.6L to 1.3L on subsequent flights to give it a little more acceleration on launch. The other two foam flights also flew well with good deployments. You could see that the deployment mechanism was ejecting the parachute well away from the rocket which was good.

All in all it was a good flight day with Paul also getting in a flight of his little pyro rocket. That now makes it 32 flights with the STII to date with only one unknown failure during early testing. The highlights video below contains only some of the flights as they were all so similar.

When we got back home we did a pressure test on the Shadow's pressure chamber too. We are pretty happy with the results because both the end caps and the tube held up to this pressure.
