XRAY - Model racing cars

A couple quick questions about the front gear diff:

1. When packing it with cleaning gum, how much gum do you put in? Do you fill it up to the pin like with oil?
2. Can you use the 52mms unis when using the kit track width and a gear diff or do you need to use the 50mms

Thanks!

A liked the diff up front with 300,000 oil in it but it was slower so i took it out again

Thanks for the response. I saw Hagberg uses cleaning gum in his so I was considering either using that or 500k.

Hi,

Tried a gear diff the other day in the front with 500,000 with 50mm driveshafts, not sure if I liked it though. It was smooth into the corners but seem to push on power out of the corners.

let me know how it goes , i would like to try it too
