Transmitter/Receivers will mine work?


New member
Hi all first post here,

Old 3D Heli guy here I haven't flown in a long time and a lot has changed. I thinks its been 8+ years i stopped flying right around the time DSMX came to be and FPV/Drones where just getting popular in my arena.

I have an original Spectrum DX7 and a JR 12X. The DX7 apears to be DSM2 and the JR 12X just indicates DSM. Neither where upgraded to DSMX don't even know if that is possible but I remember something about that back then. I'd rather not buy a new radio. I've tried researching this and its confusing with all the new protocols.

Questions: Will either of these radios work with these new flight controllers if so what controllers and receiver/gear would I need??? If not any work arounds???

My intentions are to build a Gremlin.

For the keen eyed yes the 12X is missing a few switches It suffered a fall off the counter at my friends hobby shop years ago. Going to fix that soon.

Thanks for any input.

The DX7 will work just fine with any receiver that is DSM2 & DSMX compatible. I believe but do not quote I think the JR is the same way. Many of the Lemon and Spektrum receivers are set up this way, the Lemons are a very good reasonably priced receivers.
