Lego Technic Mini Trial Truck -- GAZ 4x4

[DLuders]

On his Brickshelf gallery, Hungarian AFOL mbmc137/ 1hengeresVmotor posted 20 pictures and this

of his Lego Technic Mini Trial Truck -- a GAZ 4x4. He wrote, "This is one of my most succesful TTs, light and strong compare to the size. Driven by two Xl motor. The weak point is the front U-joint drive, but not soo wrong. Comments to - kopaszkis@freemail.hu ." The model looks like a GAZ-66 (a Russian vehicle from the 1960s). It is tethered, but can climb some STEEP rocks.

I dont like the way he routed the power by the last picture. If anything goes wrong, there will be 3x the Xl motor's torque on those U joints, breaking them.

Me as well. M motor is strong enough to steer more than a kilo weighing trial truck with the same gear ratio.

i agree with zblj, those u joints for steering and powering the front wheels are really vulnerable.

i think that when the truck encounters a front wheel to get stuck in a ditch or something, the xl would there the front axle apart, the axle is not connected trough more than 1 link, only a layers of bricks. so no heavy support. well it would break, if the u joints don't break sooner..

but a nice looking truck :)
