Unimog 8110: Usage in Truck Trials

[lukeandahalf]

@ lukeandahalf: Welcome to Eurobricks! VFracingteam posted this youtube of his motorized Lego 8110 Trial Truck:

Thank you, I am glad to finally be a part of the community after "lurking" through the forum for so long!

Has anyone had any experience with "ganging" two or three M motors together with 16t gears? I currently have two M motors powering my 8110, not quite enough power! I'm considering ripping the compressor and PTO gearbox apart and using the third M as well...

Any thoughts?

I have! Just finished it tonight. I need to get some better batteries before I can really say whether it worked or not.

I am in the same boat with batteries. my solution so far has been to use three battery boxes for three M motors. I use axles to connect the battery boxes, and another axle though the holes on the switches of the boxes so all three can be turned on at once. It has much more torque with three M motors but still stalls on some hills. My next purchase will be two XL motors and IR reciever/remote. Currently steering is "leashed" with an old 9V battery box and motor.

As an aside, I created a brickshelf account this afternoon, but when I try to view the images it says the haven't been made public yet? Curious.

@ lukeandahalf: Sometimes it takes several days for the Brickshelf administrator(s) to moderate new pictures. Until they are "made public", only YOU can see your pictures -- nobody else can. However, you can follow these procedures to "Deeplink" your Brickshelf pictures so that others may see them right away.

I like using Flickr (instead of Brickshelf), because one can easily post pictures WITH DETAILED DESCRIPTIONS, and one can select the desired 800x600 pixel size for posting here on Eurobricks. Brickshelf's images are sometimes TOO BIG to link.

I think the XL for the steering on the cab is a wrong thing. Too many gears with a lot of dead movement. When I tried, tires were free to move instead of mantain the position.

I solved putting a M motor directly on the fron suspension, removing all gears and the fake motor

But, that's only my opinion :)

Use my front axle sollution and you don't need to use a big motor to steer anymore. Car will also be more stable in terrain.

Where can I see your solution? PS: i wrote L motor but it's a mistake. I used a M motor :)

I'll post some photo if someone want view :)

Very good video! I noticed that someone had asked for a parts list for this build, any chance that has come together?

Hy i realy like your desing but it is very part expensive. Have you a less part expensive way. i would realy like to make my Unimog go up hills and still be able to turn and use the snowplow.

Hi,

Please don't bump a two year old topic, asking for a less expensive part.

There's an active discussion going on over here:
