Doesn't LoRa have a pretty constrained duty cycle? I read the regs on LoRa (for the US at least) and found that you're required to limit transmission frequency to 1% (36s/h). I'm guessing you'd have to go well past that to operate an RC aircraft in the conventional manner. If you're just commanding waypoints I suppose you could be compliant.

IIRC the 1% duty cycle is an EU restriction. The US 915 MHz band has a 400 millisecond dwell time restriction instead.

LoRa is just a protocol, there are no rules inherent to the protocol itself. Certain LoRaWAN networks have rules around how often you can send messages through them, but RC links don't use LoRaWAN.

Per channel. Frequency hopping mostly bypasses this issue.

I think if you go to 500khz you can transmit all you want. It's only 125khz that has that limit.
