spur gear tooth count for .5 crt
 

hey guys i was trying to use the calculator that mike has for motor selection for my .5 crt project and i dont know the spur gear tooth count anybody know,thanks

46t..

thanks:yipi:

Are there any smaller spur gears available? Like a 44t?

Short answer: no.

Long answer: Depends. The CRT.5 uses something close to 8th scale parts, but unless you want to modify the CD mount, CD bearings, and change the center shaft length to allow the space for a real 8th scale diff (or even just a regular spur), you are stuck with that spur. This is one of the primary reasons why people use the hardened pinions - because they are stuck with the steel spur.

Only bigger...
