Ok had a look into the build and decided to have a go.
The base is a basic springer hull with a 3:1 reduction drive a mfa 540 motor and a 2 blade 40mm plastic prop (can be changed later).
the deck is a piece of alloy signage ,looks like a piece of plastic in a alloy sandwich .I have recently bought a large sheet of 5mm foam board to make some templates for a coaster so i decided to use the off cuts for the deck with plasticard for the cab ,and the fifth wheel is made from wood which is pivoted like the real thing .
I did try to glue the foam board with liquid polly but it melts
so super glue was the way to go, once i am happy with the looks then some decorations will be applied and the trailer build can begin.
