Thanks guys! I will do my best with this build
Rvjimd,
I decided to use traxxas shafts, because they are cheap and small enough. And quite realistic.
So naturaly i choose bearing blocks from traxxas too.
They are 1/16 parts, seen in lots of 1/16 traxxas models:
I will give links, but it is possible to find them cheaper and / or closer to you. For example in local RC stores. I normaly buy them from europe union countries for fast shiping, because I am from lithuania.
Traxxas:
Axle carriers / bearing blocks
Axles
Shafts I used to connect diff (had to buy two sets, to get 2 pairs of shortest)
And used a few yokes from some shafts to mod ZD diff outputs.
Bearings
Hexes (I sugest buying aluminum version)
There of course is lots of upgrade parts, like metal shafts, metal bearing blocks etc. So for bigger tractor I would use aluminium blocks, and traxxas differentials.
Good way to choose parts is to download manuals of 1/16 traxxas. Like Slash, E-revo, Summit.
I can't find ZD diffs anymore. I bought them for low price. They vere like 5 usd a piece. And quality is quite good.
