Cool idea. I didn't know those things existed. I was thinking about getting one to try but the thought of having a 2.4Ghz wifi transmitter near my 2.4Ghz control RX doesn't seem safe.
I will try one after I move to a long range UHF radio system.
Ah.. I anit thought that one out about the 2.4 gig stuff.... eek. what about the blue tooth one? I have BT on my MK FC for the MKtool so that should be safe enough eh?
