I got the Pendle set and had the same problems. I do tend to tighten grub screws quite hard but that is as a result of having so many gears slip. The wrench that fits the SlotiT wheels rounded off the first time I tried to undo the wheels on a SlotiT kit chassis as supplied.

I will now avoid any RTRs except perhaps Thunderslot, who use sensible sized grub screws the same size as my retro cars. Just using one size is handy.
