MEUS Racing 4WS Four-Wheel Steering Control Line with Control Board and Servo Control Lines, Suitable for 4WS RC Crawler Car SCX10, TRX4, SCX24 TRX4M etc.

Haven’t tried, but I’m sure it will work as well as the no name brand ones I’ve purchased before. I love doing 4WS builds and this makes it super easy as long as you have a 3 channel remote

Was a little bit of a pain to get it set up but after dialing it in an doing some waterproofing to it. It's held up flawlessly in my custom 1/10 scale ax10 4ws buggy. Definitely would recommend. Only improvements I could see to the software could be a hold feature on where the rear tires are pointed when u go back to front wheel steer.

It's installation is a little tricky but not hard once u understand how it works the instructions are ok but not very clear so u have to try different lay outs and didn't need an xturnal battery. Works off 5.5v fine. Sorry no pics this time a u just burned up my pythonRXF an zilla motor! Sux.

Flawless. Works perfect. I did shorten up the wiring because I used for scx24 build. I would certainly purchase them again.

Works great with stock SCX24 AX-4 Transmitter. I snipped off the Ch1-3 female connectors and the male Ch2 to slim it down and I’m running two completely different servos (Mofo BlackLabel DP-M up front w/ an emax in the rear), it has been functioning exactly as needed with no issues!

I added a 4 wheel steering system to an SCX 24 and wanted more control over the rear steer than I could get with the stock setup and the limited control on channel 3. This unit works perfectly for the job. It's easy to select between Front, Rear, Both, and Crab modes and the controls match very closely front to rear.The only issue in this application is the size of the cables. The electronics are very compact, but the bundle of cables to connect to the RX is fairly bulky. It took some work to get it packaged cleanly (for some given value of cleanly) on my modified SCX24 chassis. The bulk of the wiring is tucked under the battery in the picture, but you can see how small the actual electronics are mounted below the RX.I may add 4 wheel steering to one or more of my 10th scale crawlers, where there's considerably more room to do a clean installation.

Don't plug it in wrong. I wish they would accept my return.

After spending about 20 minutes to figure out on a 5 channel, got it working, also learned if you don’t have a fancy controller, but just a simple center steering adjuster, install the servos opposite, and they will center just fine.
