Yes - but you still have to be a little careful buying within the Radiomaster product line. Radiomaster does make some radios that wouldn't talk to the r88 - such as their ELRS radios. The CC2500 radios talk several protocols like (Frsky D8, D16, Futaba S-FHSS, Hitec, Radiolink, and Esky), The 4-in-1 radios will fly just about everything (except ELRS and Crossfire).
I personally have always purchased the 4in1 radios which can talk to pretty much anything. Most of the radios with the 4in1 chips have expansion bays where you can plug in a ELRS or crossfire module. You'd only really want/need to add a module if you got into REALLY long-distance flying (like a mile or more away where crossfire is needed), or for flying quadcopters where ELRS seems to be getting super popular due to lower latencies.
I'd suggest the Zorro if you like the game controller style, or the TX16s if you want a more traditional form factor. The flitetest store has both. Also, make sure you buy batteries for your transmitter - they don't come with them.
