Spur Gear

Anyone know where I can source a steel spur gear for the VFD transmission?

Personally, I would leave it plastic, metal spur gears can be a bit loud and not super needed.

But you want a metal spur, Robinson makes 32p spur gears.

*Not 100% sure if the bolt pattern is correct.

Thanks! I'll take a look. The plastic spur I have in there stock, is pretty noisy. The rig is way louder than any of my other axials

My VFD is pretty quiet, maybe your mess is too tight? Also, maybe your drivelines are not phased correctly?

Driveshafts are phased, and I've played around with mesh but it's still pretty noisy. No binding anywhere. Not sure what's up.

If you do go the metal spur gear route it will only get louder, also make sure you have a hardened steel pinion or it will get chewed up if not.
