Hi guys, just picked up a 3PKS and although it already has a 2.4G module and receiver I'd like to be able to use my collection of Spektrum SR3500 micro receivers, just wondering which Spektrum module I will need for my TX.

Thanks
Daniel

It's working with PPM modulation only.

That's correct, it will only operate in PPM mode. The HRC stands for Hitec which is compatible with Futaba (same signal shift).
