Well I was on lunch and I figured what the hell I'll see if I can get the rear steering stuff setup. So I pulled what is at least a 10 year servo from my Losi XX and started to assemble my parts, I would like to point out that I did not purchase the official $30 rear steer kit from Axial my system consists of a bunch of mismatched stock parts
Here is the result:
I will try to take some better pictures later today but hopefully you can make out the servo sitting on the rear mount right over the center of the axle, right by that you can see the stock steering arm.
The picture below shows the temporary mounting of the Punk RC Steering Computer:
When I get my lipos mounted over the front axle this will sit on top with the RX and ESC but for the moment this will do.
When I turn the ESC on the steering computer gives me four wheel steering, when the 3rd channel is turned on I can either lock out the rear wheels or go into crab steer (which is how I currently have it setup) turning the 3rd channel off goes back to 4WS... cool right
