Hi Bill,
Since we couldn't hear any countdown I set one of my GoPro 3 on the ground
facing RRS so focal length is GoPro 3 lens.
I'm watching the DARE online pre-Strattos IV launch so I'll send you the clip
after launch. Compared to structures at RRS, it looks like the turn occurred
around 100' +/- ?

Sounds like damage from the launcher,

Bill,
Any ideas why the antenna snapped off? Was it in the same area at the
chute and shock cords? Any photos to share?

Launched a 6” rocket at the MTA this weekend.
The rocket part worked fine: clean ignition, full 8 second burn.
Bellybands worked and separated as planned.
The payload had multiple failures: telemetry stopped at 119 feet and 425
ft/ sec when the antenna snapped off at the base. About the same time the
payload separated from the rocket. (The two may well be related.) Payload
was recovered and I will download the data for review when I get home.
The bellybands were pretty chewed up by the ride up the rail. The fins
clearly tore into the bottom band on ignition (bands were 0.020” 2024-T3).
A redesign with stronger bands appears a good idea.

Hi Bill,
Here is an image from a video from FAR I took of your launch. Made a very
obvious course correction shortly after liftoff.

Yeah, you’re most likely correct Ken. We mount all our antennas
internally, so it that didn’t occur to me, but Bill might be constrained to
mount his externally with a metal airframe or surrounding structure.

Rick:
Thanks, that is a big help. Pending looking over the on board data I am
currently assuming the payload separation led to the “course correction”.
