In my opinion this is not the radio to have. Yes it has the telmetry but i was disopionted to find out that spektrum did not give it all the features that they gave the dx3r. Thing include that they gave the dx3s a smaller screen then the dx3r and they gave the dx3s less model memory. I believe that took other stuff away but i am not sure maybe someone else on hear can help me out.
In my opinion your better off getting a Dx3r since you said that you want one that only has 4 batteries. I think that that radio is more of a race radio.
just my .02 cents
