Is this a nitro vehicle? I'm guessing it is because of the servo for throttle.

Any how, press right on the d pad. That should bring up the fist page of menus. You are looking for an option called ch-rev or something like that.
Once you find it go in there and switch whatever the th is set at.

Also go in and make sure that all trims and sub trims are are zeroes out.

Now set you end points on throttle and brake.
