+1 for the DX3R I have one. went from an M11 which is a great radio also.
I like my dx3r better.
You will have to look at the differences in the r vs the s.
I don't use telemetry.
neither do 99% of the racers out there.
I'm not sure what the diff. are?
I would think the 3r or 3s you will be happy.
just depends on if you can wait.
