Trailer with rear steering axles

[elliot330]

Hi All...

I'm in the process of building a low boy but with steering axles on the trailer. At present I am controlling the trailer axles by a channel on the radio, however, my head is in overload when trying to navigate a corner!

Is there a device that when connected to the 5th wheel/ King pin, that detects an angle between the trailer and 5th wheel, thus operating the rear steer automatically?

Thanks in advance.
