This is a 1/18 scale 5'x8' utility trailer I designed and built to pull behind my 1:18 RC pickup truck. The axle has two bearings in it for smooth rolling, and the ramp uses magnets for a strong latch with no moving parts. The coupler on the trailer is spring loaded using the spring from a ballpoint pen. The trailer is designed to latch to an M3 ball screw.
In addition to all the parts I've uploaded a step-by-step installation guide with pictures and part numbers/links for the bearings and magnets. Enjoy!
