So one 4 wheel steering mod write-up has been done, figured I would add my $0.02. This is a full 3ch mod. With the controller I used you have push button selection between front steering, rear steering, true 4 wheel steer, and crab walking.

I went with the Redcat Racing 3ch tx/rx combo.

For a new ESC I went with Hobbywing Quikrun 1625

While I was redoing electronics I decided to up my servo power(these don't come with servo horns)

Thanks to a little trouble shooting help after the fact @steven81 pointed me to Castle's programmable BEC. you will need this to prevent "brownouts," which I was getting ALOT before install.

Other things you will need are a 2nd servo mount and more steering links. Nitrorcx has the ones from the Maxstone Exceed for a bit cheaper than HH for the Temper

For a servo mount I just used a one piece, since as of writing this the stock ones are back ordered for months. This mount will require some new holes drilled to mount to our axles, but is pretty straight forward.

From here on it's pretty straight forward. hook up your new electronics, and you are ready to rock. Be aware that with the BEC installed the power switch on your ESC will ONLY turn the motor off, the servos will still receive power until you unplug the battery. Below is a video on how to setup your BEC, I recommend also ordering a castle link to program it to 6V(my LHS did this for me at no charge), as its set at 5V stock (6V provides plenty of power, without smoking your new receiver)

Sorry for the lack of pics of install, was so excited to get it going I totally forgot, but here is some pictures of the final product. I'll post a video when I get a chance.
