Unimog

My third real truck trial. I created this with all the knowledge I have learned from the privious trucks, and from what I have learned from other trucks I have seen. This truck uses a number of ideas I have gotten from Aro-Kal, including his superb Unimog U1650.

I used the rear axle from my Unimog U500, as it leaved nothing to be desired. The front axle was redesigned to make use of a turntable 48452cx1 for less drive line stress, and to have the drive and steering move through at the same place via a differential. I also wanted to use the new steering rack 87761 , as it seem to be made for this application in a studless chassis.

Suspention is still pendular, though on this model, each axle was suspended using a number of the rubber axle connector 45590. This proved to be a mistake, as it would cause the truck to rock when it would drive over uneven ground. The truck would tip over a lot.

Drive was good however. The driveline gave adequate power, and the 9:1 reduction of the two PF XL motors gave the truck plenty of power. The redesign of the front axle gave the truck much needed steering help. This helped reduce the turning radius, and gave the truck a more nimble steering control.

Already working on a new truck to deal with many of the issues discovered with this truck.
