flying RTL-SDR RPi

[Alex Fraser]

Yeah I will end up modding the WiFi antenna on a Raspberry PI, not on 
the drone.  I got my non commercial licence to fly, numbers on the drone 
and I check the "B4you fly" app every time.  I'm South of the "No Fly 
Zone" (ha, we still have screens on our windows...).
