jrsx3 problem

[t-maxxracer32]

hey i have had my revo for like a month now and am using the jrsx3 radio system and love it, but i went out and bought the 5995 hitec servo or w/e it is (the 333oz) and i installed it and everything was going good but when i turn left the tires turn right and vice versa.. i know on the normal remotes you just switch that thing on the bottom of the transmitter to the other side but on this one its all digital... so how do i make it to where i can turn left while turning the steering wheel left!! lol any help is greatly appreciated

thanks
