I am contemplating building an Furibee F36 to - among other things - have an F3 FrSky compatible flight controller from Gearbest so it can be used with a Taranis Q X7.

One point that I am wondering about is EU legality. The info on the Gearbest FC says 'FrSky D8'. D8 RF mode is generally not usable with the EU LBT radio software (though I have read somewhere that the latest version may support it), but either way, D8 on an international receiver is not going to bind with D8 on an EU LBT transmitter.

Therefore, it seems to me that to get this to work, it will be necessary to have non-EU software in the transmitter, which isn't actually legal.

Is this right? I'd be interested to hear any opinions.

It's perfectly legal.

It's only illegal to sell non-LBT transmitters after the law was introduced. If you already possess a transmitter that does not comply with the regulations, you are not breaking any law by using it.

I guess that leaves as a 'grey area' those that were purchased abroad but after the law changed.

A law that changes technical requirements of equipment cannot be made so that it applies retroactively.

Obviously, if you buy something from abroad which does not comply with the law then both the supplier and the buyer are breaking the law. However, the LBT requirement only applies to transmitting equipment - a receiver that isn't LBT compatible is not a transmitter and therefore does not break any law. 


I use DeviationTX firmware on my radios and I can choose which protocol my radio uses when binding with an FrSky compatible receiver. Maybe OpenTX has similar functionality?
