my erbe came with a 2.4ghz receiver and its great but very basic.

I see so many ppl wanting the DX3R and not much about the S.

What is the difference between them? i know they both have telemetry, so why does everyone prefer the R?

The DX3S(sport) is a cheaper version of the DX3R(Race). The DX3R uses DSM2 technology, can hold 20 more cars, has more options and has a lager screen. There are othering differences, but I can't remember.

The DX3s is the only one that has telemetry, DX3r does not. I prefer the 3s since it has telemetry and a second reciever for cheaper.
