My requirements were very similar to Jeff's, and I too looked awhile for a case to box it all up in and ended up sacrificing my micrometer case to the cause. I used the GPIO header for all connections, and a 3 amp SBEC from the R/C side of my habit to power it from the ship's power, paralleling both 5V in and Grd GPIO pins to minimize voltage drop. The wiring is set up for AHRS, but I didn't bring it out of the case yet, pending Stratux tweaking the details, and hopefully iFly developing the Stratux interface for it.
The 5v load is about 1 amp, the 12v load is about 0.5amp, the CPU is running about 15F over amb with the fan. The Pi goes in my glove box, the 978mhz ant. is belly mounted, the GPS and 1090mhz ant. are on the glare shield.

Nice! Mine has since been moved to a clear plastic case from Hobby Lobby and the GPS chip is in a soap bar travel container, but I'm still on the hunt for the "perfect" package. Yours looks custom made for it! Even with ample power, I experience an occasional wifi drop that sometimes requires a Pi reboot to resolve. Do you ever get that? I'm using the TP-LINK wifi dongle. Which are you using?

I'm using the Edimax EW-7811Un and not having any such problems running Stratux v0.4r4. The previous version 0.4r3 was another story; lots of no heartbeat, drop, and freeze problems, which were quickly fixed by the developers. I'm still looking for a GPS case, right now it's in a little plastic zip bag.....
Update: I had what I believe to be a Pi crash at about 30 minutes into this morning's flight. No heart beats, my 720 went on internal GPS, but still showed the Stratux as connected. A reboot and everything was back to normal for the final 25 minutes of the flight. Thinking back, I could be wrong when I said I haven't had this problem with v0.4r4 before, what I thought to be a internal 978 ant. problem (also at about 30 minutes into the flight) may have been what I saw this morning.
Do you recall the timing of your problem?

What are the specific parts we need for gps and AHRS and where did you get them? Thanks.

OldPilot,
I'm using a RY835AI ($42) from EBay for GPS and AHRS functions. If you don't need AHRS a RYN25AI ($15.50) works well and is what I'm flying until AHRS matures. Both come from across the pond.
