This reminds me
I found my Flysky USB cable
and my JR R1 has a suspiciously similar port labeled DSC
in the manual, it shows an adapter that plugs right into an RC, so in the olden days before 2.4GHz (mine has a spektrum module now) you could test your RC in the pits without wackin' out the people racing by turning on your transmitter and adding one more frequency to the mix (there's a seperate switch to power on the TX, but not transmit anything from the antennae)
I wonder if that USB thing from my flysky would work?
I completely forgot about it until right now
too bad my demo is most definitely expired lol.
