Default Question on spur gear mounting size and position

Anyone knows the industry standard of Spur gear?
I am currently working on DIY project that use 1/10 EP spur gear's mounting, but I don't know the size and position of those holes.

I don't think there is a standard for a spur gear...I would try a Team Associated spur, also available from Robinson or Kimbrogh (not sure about the spelling). It's a common gear used by many manufacturers. 48 pitch is probably the most common in 1/10 scale racing.Hope I understood your question correctly. Oh, don't pay any attention to my user name. It's just a coincidence.

Most spur gears use a 3/8 in. hole, in the center. The outer hole are brand specifc. Hit up a locwl hobby shop and compare brands.
