  1. 1. Which mini model would you like me to build using this idea



Recommended Posts

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.

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

This looks as a very nice and compact solution. :thumbup:

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?

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 :wub:

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

Tatra 10x10 http://www.eurobrick...=84135&hl=tatra

Tatra Kolos http://www.eurobrick...&hl=tatra&st=25

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.
