The Western Australian Rocketry Society INC. cordially extends an invitation to WARS & AMRS members and their invited guests to attend the range located at Grass Valley 75kms east of Perth, on Saturday the 17th of September for one of our regular club launches for the 2016 season.

The CASA instrument permits launches of HPR up to a maximum ceiling of 7,000ft. DMP has given permissions for the use of J, K, L & M impulse motors.

Facilities will be available onsite for AMRS members wishing to attempt L1, L2 & L3 certifications

The range will open for operation at 09:30 and will continue through to 17:00. Any assistance with range setup is appreciated.

Hey Strud,

Weather was magnificent, clear blue sunny skies, very little breeze, and a great turnout of peeps.
Plenty of flights, and a bit of carnage as well!

Deeman took a few picies, as did Drew & Simon, I'll need to go through the photos Dee took to post.
I'm sure Drew & Simon will post as well.

There were a bunch of good flights too and two new Level 1 certified rocketeers!

Apologies all, I've been a little sore from the weekend. I flew my half scale AMRAAM on a K300 only to have it CATO spectacularly mid flight. All the electronics fared well, GPS was still giving me lock on the ground, but my Yi camera might be toast as the NC took a hard hit. The lower part of the airframe below the forward fins is TRASHED. I've got more photos to share but I figured I'd quickly chime in and share the before and during shots.

Liftoff and everything looks alright.

OH DEAR.

I'll share more soon, including my 54-6GXL case that's now in two pieces. :x

Misery...

You say case in two pieces, does that mean you had a burn thru the wall ?

It looked that way to me, there's a deformation in the case that looks like a bubble started to form before it blew through and then tore right around.
Will be interesting to see whether it was between two grains or grain/delay.

Yep strud, full burn through and then the entire thing peeled back like a tin can around the diameter of the motor. It appears to have happened between the forward closure and the top grain as I've been told the top part of the casing is maybe 1-2 inches in length. Maybe I had an O-Ring fail? Scoop has the top bit, I had to leave the launch early to go to a birthday party for one of Jodi's old co-workers. Below is a photo of the 6GXL casing in the 54mm-75mm GLR Motor adapter that I flew post calamity.

No good Drew. I thought that it looked like your AMRAAM in Simon's video and the audio didn't sound great. How long into the 8 sec burn was it when it CATO'd?
Many years ago the great British explorer George Mallory, who was to die on Mount Everest, was asked why did he want to climb it. He said, "Because it is there."
Well, space is there, and we're going to climb it

I wasn't sure as it was all a bit of a blur but going by Simon's video I'd say roughly 4-5 seconds into the burn is when it let go...
