Hello folks,
Technically this is my first thread, so bear with me on this post. I crashed one of my good rockets on a supersonic flight to 9200 ft this past weekend and I'm trying to troubleshoot. The thing is, the data I got back from the unit is a bit strange. First, the peak altitude reported is 20,000 ft - I know I didn't break 10,000 ft. Also, at the 39.25 second mark the data makes a big jump in altitude (while descending) and looks exactly, and I mean exactly, like the previous flight from that point.
I know that the MAWD fired the apogee charge, but the main failed to deploy. After the hard landing, the unit was "off" and not beeping. I opened what was left of the ebay, and it started up. I know you are thinking "loose wire", but I was unable to find any and the switch (aerocon PCB style) was still tight, 9.07V on the battery too.
Prior to the crash I had 53 dual deploy flights with this unit, and only 3 hard landings (13 successful flights since the last hard landing). I'm well experienced with dual deploy, with 130 of my 153 HPR flights being dual deploy and I'm L3.
I've attached the files of interest (.pfd changed to .txt). I'd appreciate any help - I suspect that the unit lost power mid-flight, but I'm not sure why.
