Few years ago I made the first big scale portal axles...

Now its time to do same at small scale!

Here's the result:

The axle has a 1:2 portal gear ratio and uses the CV joints for steering. Steering is done via 7 stud long steering rack. Its meant for lighter smaller scale models, like the ones Madoca77 is famous for.

I also made some variations of the axle and to top it off I also added the mini 8x8 tatra chassis.

Some video footage:

So what model should I make with these? Please vote! Thanks!

Are you going to make remote controlled vehicles with them?

Yeah of course RC

I can only vote for one?

You once made a little unimog without motorized drive and steer, so thats why i ask.

that's looking good!

i'd make an offroader with that!

I'd like to see a mini 8110/unimog

This looks as a very nice and compact solution.

The only thing I am not sure about is the bracing of the 8 and 16 tooth gears. Will two half bushes and weight of the vehicle be enough to prevent gear skipping?

As shown in video they slip when there is the torque of XL motor (which is overkill). I guess you have to build and try?

Yes, I like the design, so I will try it. Thank you for sharing good ideas.

Your big scale axles were the biggest inspiration for me to get back to Lego and start MOCing.

Sorry for offing, I just wanted you to know

That means a lot to me!

Back on topic seems like the more wheels the more votes

Why not new hubs in the Tatra?, they were great for my two Tatras.

Tatra Kolos http://www.eurobricks.com/forum/index.php?showtopic=82416&hl=tatra&st=25

A mini Unimog with the same cab and bed design as 8110 would be my pick anyways.

Ground clearance is low under those hubs.. Anyway my tatra 8x8 is now complete and I will be posting its pictures in the next day or two.
