Kyosho RT5 - differential adjust screw - on LHS..?!

[tangled]

Bought, on a whim, an RT5 on eBay and having built it up I note that the instructions state (even draw attention to it) that the head of the adjustment screw in the differential is on the LHS.

This is a first, and a mate commented on it... had got me wondering why all other cars I've built/seen have had the screw on the (same side as the slipper clutch adjustment) RHS - would the screw one side or the other reduce it loosening off as the whole assembly rotates..?

What side is it on other Kyosho's, just out of interest?

Any thoughts/comments welcome!
