I've never had much luck with Spektrum radios for surface use, they tend to provide top notch stuff for aircraft but don't put the same level of quality into their surface controllers.

That said, I've had really good luck with Radiolink surface controllers over the years. The last version of their radio that I used was the RC4GS, but the newer RC6GS offers telemetry where you can get readings on the radio itself making it easier to see. With Spektrum you need to look on your phone to get readings which is extremely impractical.


Better yet, the pricing for Radiolink is lower:
