Cross RC Ural 4320 Project

uc6

Cross RC came out of nowhere.  One day I had never heard of them, the next day I was feverishly researching them, and the day after that I was searching for a UC6 to buy.  It started with a YouTube video of a PG4 dually truck.  I thought the quality looked really good so I went looking and found I was very interested in their line of scale military vehicles.  I had never built a 6x6 before so the UC6 (a model of a Ural 4320) really caught my eye.  The problem was, there were no distributors in North America at that time and I didn't trust some of the overseas sites where I found the model.  I ended up ordering one off eBay without totally knowing what to expect.  It was a big gamble because this is a rather expensive kit.  In the end, I could not have been more pleased.

This is a 6x6 truck.  All axles are fully driven and locked: no differentials.  The chassis rails, axles, and gears area all metal.  The hard body shell is highly detailed with a full interior.  The set includes a full light kit with working blinkers, brake lights, and reverse lights.  If you have a channel to spare, you can also turn the headlights on and off.  The light system uses printed circuit boards so everything just plugs in.  There is also an available sound kit which I picked up.  The speaker sits behind the grille and sounds quite good.  Out of the box, the bed is open but includes a box for the battery and foldable seats along either side.  I chose to add the optional canopy.

This heavy rig is an unstoppable juggernaut.  It has as much power and traction as you could want.  It is extremely durable despite the glued plastic body.  Building it will test all your modelling skills.  I went the extra mile and added some rust spots, mold, and other weathering.  Later I came back and built a scale howitzer to tow behind this rig because, why not?

Update:  This model was destroyed in the 2022 fire.  It has not been replaced.
