Cross-RC UC6 tank hauler

[Billdit]

The trailer I designed on 2d autocad, basically I measured the length of the tank and made the trailer to suit. The tank weighs around 8kg, so the trailer needed to be fairly strong.
My idea was to make to spines the full length of the trailer and bolt it altogether with cross members and outriggers.
I made the spines from 4 pieces of 1mm sheet steel and sandwiched perspex between each pair.
After making wooden templates and cutting out the steel, this is what I ended up with.














The next fun part was cutting them out.

After much cutting I made a bracket from steel which would space the spines apart at the front and also double up as the coupling pin mount. I sourced a trailer for donor parts, mainly for the suspension, but also for body work to make the bed for the UC6 truck. The trailer came from Cross-rc.



Once I built the suspension I bolted the spines to it and hooked it up to the truck for a test fit.

Now for a suspension test, will it be able to take the weight of the tank? The simple answer was no!

The leaf springs were just flattening out on the truck and trailer...









So I increased the amount of leaves which sorted the problem.

I added the correct wheels (to be painted) and a new fifth wheel with pinion and it's atowable trailer.

The next step was to add the cross members and outriggers. These are made of solid aluminum square rod which was cut and threaded by my local friendly machine shop.
Once I got them back, I bolted them on and this is the result...

Running boards next. These are made from 60mm x 5mm flat aluminum and are bolted to the outriggers. As the scale of the tank is a bit small, I purposely made the running boards narrower so the tank tracks overhang to give the effect of a large tank on a small trailer if you know what I mean.
