Good post.

I've been drilling and tapping gears for some time as quite a few have suffered the ravages of time. Quite why I didn't think to attack the wheels in the same way, I'm not sure. I only have a few modern RTRs but they all seem to suffer apart from Thunderslot who use sensible size grub screws. I don't have any NSRs.

I will immediately go and make them usable again - thanks
