Scale drop deck trailer. This is roughly an eighteen foot scale drop and load style trailer. Deck can be made from a single sheet of whatever material you want. I recommend that you use a sheet of G10 (fiberglass) its pretty cheap and you can cut it with a lot of stuff. Sheet size maximum width is 200mm (shown) and deck length should be around 560mm (560 shown) can be a little longer or shorter. Deck MUST BE one piece it is attached with four counter sunk screws. Trailer can be equipped with six 5mm LED's. To make this trailer function you need two actuonix 20mm linear actuators and sub 60mm eye to eye shocks/coil-overs. I recommend that you use shocks for the 1/14 tamyia semi's. Use 64mm diameter tires max (touring car tires & wheels). You will need eight 5x11x4 bearings for the axle stubs. Axle stubs are traxxas 2wd front stubs. Use all M3 countersunk screws, and any M3 ball end and ball you want.
Recommend 4-5 perimeters. 1.6mm side 1.2-1.4 top/bottom is what i would do.
