I have a HPI TF-4 that i am using on my AX-10 to control my rear steer set-up, and it only turns on way in the rear right now! What do i need to do to make it control both directions??? 3 position toggle? Has anyone every messed with this radio for this type of app? any help would be great! --Mike

do you want to control the rear separately from the front or with it???

if you want it separate then you will need a 3 position toggle

if you want it to steer with the front just put in a servo reversing y harness
