just spent around the last 2 hours changing over the chassis rails, the ones i have now are not stripped and i have gone back to the imperial screws. For the load bearing screws i have gone back to the imperial ones as they give a better 'bight' into the plastic, this is mainly because the rails have already been tapped for the imperial screws.

why of why can't losi go to all metric screws. (just kidding but seriously)
