After having a look at the below upside down mounting of an APM2.5, I thought I would share my APM mounting as an alternative. I created my own Bixler 2 canopy with some plastic board I bought at the local Bunnings warehouse for a couple of dollars. I ripped off the original plastic and stuck it on, as well as installing some hobbyking rare earth magnets for a decent mount. It seems to work really well, and keeps everything well contained. I was able to fit a minimosd in below the GPS, and the wires at the back feed to the FPV camera and the 3DR radio.
