I've receive the PicoAPRS device and have it piggybacked on my Autel EVO drone. 
  I've had it up for a couple of test flights and can confirm that the PicoAPRS 
Velcroed to the top of the drone doesn't seem to affect the flight dynamics of 
the drone at all.

Full details on the "Flying Digipeater", including pics, are here on my website:


I've had the "Flying Digi" up at about 15 feet above ground level so far, 
testing for stability and EMI/RFI issues between the drone's radios & 
electronics and the PicoAPRS transceiver.  So far, no problems observed.

Later this week, I'mm going to send it up to around 350 feet and see how much 
APRS traffic it digis from around lower Michigan.
