RE: RedCat Spur Gear? Steel Spur Gear vs. Plastic Spur Gear? Pic Inside?
I would also recommend staying with the plastic. I have different models with both steel and plastics spur gears, and like what was already mentioned, you'll wind up buying clutch bells or other more expensive parts. Stick with the plastic, set your mesh up right and keep an extra spur in the parts box.
