I saw the disney car trailer and thought "custom" for one of my primes, it opens just like g1 and is well detailed with indents and lines etc. I was origionaly going to create a trailer for animated prime but the wheels on this were too small then I found a spare magnus in my custom box and thought full out custom.
the recipe for this was gloss black plasticoat paint and various acrylics for prime then some stickers from a wst prime that were spare. Then I gave him a cannon from a knock off figure. The trailer was made from a cars trailer gutted and stripped of stickers, resprayed with plasticoat in smoke grey colour with acrylic colours and silver duct tape for the stripe, teletron one is a knock off helicopter flipped over and a few random missiles glued in to give it a battle station look. the minicons and bumblebee store away without hinderence and the ramp is perfect size for bumblebee.
not a great custom as I was hassled by my toddler son so I intend to redo this at a later date. need to find junkers and parts to create a more accurate teletron 1.
stripping magnus down to paint took the longest part the trailer was suprisingly easy, Although I bodged the autobot logo on the rear door I'm happy with it for now he looks cool next to g1 prime.
