Just wondering if the ADIS16365 make up for its price.

Are you doing everything as interrupt-driven (autopilot-wise)? As opposed to using something like FreeRTOS?

Their blog says it is itnerrupt based. From my experience I prefer RTOS but I presume that is harder to pull off with minimum resources in a microcontroler vs a full microprocessor environment...

Nice looking airframe. I assume that tank looking thing at the nose is the fuel tank, and if it is you'll want to look into your CG travel as you burn fuel. With the tank somewhere away from your CG, as you burn fuel your CG will travel and require more "tail" (aileron in your case) authority which a flying wing doesn't have buckets of. This will ultimately ruin your performance…which is why it might be best to switch the location of your electronics and fuel. From the looks of your plane you might be able to put tanks in the wings as well, but you’ll want to check CG travel when doing that as well. If the wings are straight and at the CG then your whole problem goes away.

Good looking bird!

Arash: The ADIS16400 that we use is an amazing device. The only problem I have with it are the magnetometers which are a little bit quirky and need quite a bit of calibration.

Michael, Alex: Everything is done on bare-metal necessitating an inetrrupt-based approach. There are no off the shelf operating systems running on the ARM9.

James: The front white piece is not the fuel tank. It's a protective foam block which also includes the batteries and any counterweight required for establishing neutral stability. The fuel is contained within two bladders on the CG. In the illustration, they are the two rectangular objects at either side of the middle section.
