Might sound weird to use x-mas money to buy something used BUT IMO if you only run electric I see no reason to buy a 3S, all the telemetry stuff is ment for nitro. Yes some wire it up to check battery voltage and stuff but from your other posts you seem to be more of a racer than a basher which you don't need any telemetry for. Back to my monsy point, you can find a nice used 3R for the price of a new 3S.

What do you have for a radio know??
