This truck was my first attempt to the Lego Truck Trial challenge. It complies with the "original rules", as it uses 2 9V motors for driving. The suspension is done via articulated chassis.
Motorization: Due to the scale, the articulated chassis is quite fragile and each axle is driven by its own motor. Motors are linked to a differential via a worm gear, and finally a 3:5 reduction takes place just before the wheel. This final reduction is imposed by the front axle configuration.
Steering: Noting special, but I am pleased with the integration of the motor. The time for steering is just fine. I didn’t use a clutch gear to avoid problems in max steering but I tend to be cautious with my legos, and i make sure I don’t over brake.
Additional stuff: No onboard battery, no steering wheel ... It is quite bulk for a truck :D but it was my first one ... Note that the rear axle is higher than the front one. This is good for design i think, and doesn’t impact on the performaces.

Old comment, but didn’t notice it. You can do better, of course. But someone else can do even better than you. So what is the point stressing it ?
2. Sorry-did not realize this was your first...or was it a example..., 24 October 2011, 02:22, by 88high
Was the truck used as a example to the other joining builders on how to write a article about Lego Technic Truck Trial? Or was it built to give the idea to new builders what TruckTrial is about? Still, I think you could have tried harder and possibly made it a bit more better-looking...or better-operating...Just my opinion...
