B4 spur gear

[Rick]

could someone please tell me what size spur gear comes with the kit. Is it the same on all kits, team, factory, RTR, etc.

[Doomanic]

The standard spur on the Team and RTR is 81T.
Dunno about the FT, not seen one yet.

yes 81t is kit spec and all I ever use just keep a range of pinions ;)
