We launched out full scale rocket in ROCC's field on the last weekend of January, and half of the rocket was a success (the other half plunged to it's death). Instead of explaining everything that happened, I'll just post the video below.

If you watch long enough you can see that the nosecone and top half of the rocket were able to stay connected to the parachute, but the lower body tube came off and plummeted to it's death. It's actually all still okay externally, but one of our fins cracked. The bulkhead inside of the lower body tube split in two, and since it was attached to the upper part of the rocket through the bulkhead, our rocket came apart. Here's a picture with the two halves:

So next time thicker bulkheads and better adhesive.

Just for fun, here's a video with a close up of the engine going off- it knocked over the camera though.

We used a K motor, but it was "sparky," and if you watched either video you can see why. They guys at the field were a bit upset that we didn't tell them it was a sparky motor (because we didn't know). If the field is dry, it can easily set it on fire by sparky motors (especially with larger motors). The field was wet enough that it did not catch on fire though (there were fire extinguishers close by).

Here's a general picture of the launch:

The ejection test (to see if our parachute would eject properly):

On a different note, we were granted the kickbox again for the purpose of putting together a more complete ebay like what we would need for the IREC competition. I'll be adding Julia Filloon (she's in charge of the kickbox this time) as a contributor and she'll be posting kixbox related things here.

Also, I'm trying to push the team to start making our own motors- hopefully I'll have more information about that in the future.
