Powering it would require a REALLY long USB cable, or a 12/5v converter close to the Stratus in the wing. Super long USB is prone to loss of both signal and power and is not a good idea. I'd keep the stratus in the cabin where it can see the sky from a shaded position - it doesn't need to be fully exposed at all. Then run a remote 978 mhz antenna to where you can see the ground well.
