Too heavy and pistons too big

its 27kg too heavy and i said that lol, and the pistons are not too big, check out the info and look at the Area.

u r not obliged to start the engine to make work ur vehicle u just need to press right or left ..and he's too large , too heavy and the piston are pointless ... u remove all pistons and he still continue to work ...

Heres what happened, my engine was already programmed to change direction with left and right. In the contest scene the trailer has controls that were right and left arrow keys. and i cant modify the trailer because of contest rules. the spring engine needs pistons to function, i have no idea what you mean when you say the pistons are pointless. it shakes a bit because i scaled the engine.
