Tamiya Durga DB01 EP Buggy (A cheaper 501X?)

[dimblum]

I have been trying to fine tune the belt tension of my Durga, and was looking for some advice.

I have always been running my Durga with the belts firm, but not stretched.. This seems to be the best tension, but I am not entirely sure since I could not find any information to confirm one way or another.

Is it better to tension the belt so it stretches a tiny bit between the pulleys? Or is this a bad idea?

Thanks.
