Finally, much later than I originally expected, Crossbow LRS, my DIY medium range RC radio link was used to control something that flies. Not much, and not far. It was only my experimental 6″ GPS Racer quadcopter. And I reached only 350m. Small steps, I had no intention to beat and records after all.

Just as reminder, by RC link is as follows:

• Based on LoRa32u4 II development boards
• Semtech SX1276 868MHz
• Programmed with Arduino
• Planned range: up to 5km

Next test, this time without twitching, in a few weeks.
