Is this receiver compatible?

I’m trying to figure out reciever/transmitter and the controller that I use to control it all. Its a big learning curve lol.

Anyways, I came across these, they say they are PPM compatible but the docs don’t mention them.

That is a DSM2 receiver. Don´t buy that. DSMX is Spektrums latest technology. I would go and get a TX/RX that is mentioned in the docs.
