This mini truck trial was built two months ago for a local competition(finally I can not assist :( ).
The most important rule was the widht limit: only 14 studs.
The total size is 40x14x19 studs
It is a 1:22 scale of this truck
It uses 2 XL motors for drive, one for front axles and one for rear. And M motor for steering.
It has Ackerman steering between axles
Also now you can download the instuctions step by step in the INSTRUCTIONS page, enter and access to the Download folder
You must change the yellow liftarm 1x5 thin por this part (better in black ;) ):
No 2711 : Technic, Plate 1 x 5 with Toothed Ends, 2 Studs and Center Axle Hole
