Very cool
Where can I pick up these stub axles?
I made my own Square hubs from Delrin and turned down losi bolts to adapt traxles outer stubs to FG wheels.

Thanks

Looks like they are the stock 8 mm stub axles with flats ground on them to accept the grub screws is the hubs.
That should be quite easy to do on any 8mm stub axle I think?

Stock what?

this is a hybrid, right?

Coming up Blank on mt4 stub axle, or 8mm stub axle, thundertiger stub axle.

Pictures are nice to look at, but dont know where part came from..??

As far as I can see in the exploded views, both the MT4 and the ST1 came stoch with 8mm stub axles, like almost every 1:8th scale car I know of.
In the pictures I see a standard sub axle with some flat spots ground on them, done by the owner.
The MT4 comes with these axles, not in stock, but you should get the idea:

The FG square hubs are like these, the part number depends on the width of the hub:

The other pieces look the be just a peace of brass pipe, with a ID of 8mm, and a bolt that fits in the axle, you should be able to get that in your local hardware store, or at a machine shop?

I think I am misunderstanding you, my English is not that good, sorry.
