lomtafix’s Trial Truck

The truck have a good groundclearace and runs over the most obstacles in our forest.
The frontaxle is fixed but in the rear I have a pendular suspension. They isn`t a spring, to stop the overturn. I only used a rubberband. That makes the suspension a bit stiff.
The battery box is in the front of the truck. Beacause that sometimes the truck overturn to the front. If you want to drive downhill, it`s better if you drive bachward.
The gears are a compromise of fast and powerfull driving. In the truck trial race I used a smaller gear. Than the tires lose the grip, a short time before the engine haven`t any power, to turn the wheels. With the other bigger gear, sometimes I haven`t any power to drive forward.

In the second part of my truck trial race video you see, like the truck climb a hill with a slope of 50°. The videos are on my homepage.
