XRAY - Model racing cars

Hi everybody

Got a few questions about the xb8e ..

- what is the number of ball bearing set that comes with the kit ? ( how many ? )
Is it 22 or i'm wrong .

- how can i determine the size of the ball bearing ending with 814 and 816 ?
It's almost the same in diameter .

- i'm mainly running on road . What is the best setup for the active diff ?
Thanks all

In the XB8E are included 22pcs of bearings.

In the instruction manual are showed all bearings in scale 1:1 so you can check which one is 814 or 816.

Thanks a lot . The 814 & 816 caused me a big a trouble after i built the diffs as i mixed between them in the instalation .

As per the active diff setup #. 355105 , i read the instruction page and couldn't fully understand the function .

To me, it apears as when applying 120 degree setup, the diff will accept power responce without any breif delay and that is suitable for slippery & long track which is more equal or simillar to on road conditions . Right ?
I think that i'm going to the 120 degree setup in this case .
