June is Honest John Month-Let's Celebrate with a New Photo

[Tim51]

I launched it on an Aerotech M1075 Dark Matter. Here is a link to a video. Unfortunately there weren’t any real photographers at this launch.

Great flight, great motor! Thanks for posting.

Here are a couple photos from that day a little more close up to show some details.

Superb job! So am I correct in thinking the switchband and avionics were located amidships, in line with the 'R' in 'ARMY'..?

Tim,
Yes, that is correct.

Yup. A little pucker factor there for a second.

But it landed gently a few hundred feet from the pad.

What was the main deployment altitude set at? Did the charges actually fire a noticeably later than expected?

Tim, it was set for 1000 feet. I think the charge went off at the correct altitude, but that big chute took a little longer to unfurl than I had expected, and then it partially deflated when part of the airframe hit it. I changed the way I rigged the recovery harness as per sone folks suggestions and set the main at 1200 feet for the second flight.
It’s a tough design to pack your recovery in because it is almost 1/2 nose cone!!!

Thanks. Granted, the airframe strike on the chute was a momentary problem, but otherwise to me everything looked great, so given the comments I was just wondering if there had been other issues.
