Further Description/Back Story Having a real MK5 2008 VW Golf 1.4 TSI (similar to the popular Golf GTI, but with a 1.4 liter engine turbo- and supercharged, producing 140 HP) and a trailer for the home needs, I decided to build a scale Golf at first, using as a base my HPI Sprint 2 and a Matrixline 2-door Golf GTI body.

I made a few modifications when masking the bodyshell, so I could present it as a 4-door, like my real Golf and I didn't use the bodyshell's stickers for the front grille. Instead I painted the grill to replicate my real car's one. I made small stickers with my home inkjet printer to match the real car's stickers and logos. I did the same with the trailer.

After a while, I did a quick mod and added a tow bar, using spare HPI Sprint kit parts. I replaced the rear bumper with a front one, and using a battery bracket, I made a towbar. For the towball I used a swing arm outer axle.

Then I built a trailer, to replicate my own real trailer, using balsa wood, thick Insta-Cure CA and model airplane 60mm diameter foam wheels to closely match the car's 62mm diameter tires.
For the trailer's axle I used a 4mm rod. After cutting it to size, I tapped the ends and used M4 self locking nuts to secure the wheels. Sorry, there's no suspension on the trailer, but as you can see in the video it still works decently!

I airbrushed the car with color provided by a loal auto parts shop, which replicated the exact real VW color code. The trailer was painted with a typical rattle can spray in silver. I installed the full led system to the car and made an extension to power the trailer's rear lights, using a set of Dean's micro plugs.
The car uses 8 led lights, mounted inside the buckets supplied with the bodyshell. On the trailer, at first I installed ingle leds but the result was not the desirable, so I soldered an extra pair of leds for that scale look. I stuck silver tape under the trailer's leds so that the light would only show from the rear and not the underside of the trailer.

I painted the rc trailer's rear door the same color as the real trailer's, which is the exact same color as the Golfs'.

Fun facts: The trailer's rear light buckets came from empty pill cards! I painted them on the inside with Vallejo lexan paint!
I used a real silver chain for the trailer's door, which was given to me by my supporting wife! (It's probably worth more than the trailer itself!)
