flying RTL-SDR RPi

[Martin]

One suggestion for keeping things light - solar over batteries.  I like
Powerfilm
<https://www.digikey.com/en/products/detail/powerfilm-inc/MPT4-8-75/9559471> at
1 g each but it could get a little expensive.  Polysilicon
<https://www.amazon.com/AOSHIKE-Polycrystalline-Silicon-Photovoltaic-Charger/dp/B01NCQRCQR/ref=sr_1_3>
are
cheaper but more work.
