Pinion Grub Screws
I have an assortment of 32p pinion gears I want to start using again. My problem is that they are missing the grub screws. Can someone give me an idea as to what size I need to buy? How many sizes are generally used in RC pinions? The ones I need are smaller than those that fit in my 48p pinion gears. Any help would be appreciated.

Not sure about the 32p gears, but some older 48 & 64p, Robinson for example, use a 4-40 x 1/8 set/grub screw. Uses a 0.050 hex wrench.
I think most new 48p use the larger 5-40 x 1/8 set screw. 1/16 wrench size. Believe Losi always used this size.
