The DX3R uses DSM2 technology, it's faster responding than the original DSM that the DX3S. Also the R will work with both DSM1 and DSM2 rx's where the S will only work with DSM1 rx's. I had thought about selling my R to get the S cause I like the idea of knowing the temps and voltage as I'm running but since I already have a couple DSM2 rx's and they aren't compatible with the S I decided not to do it.
