Frequent Questions & Answers
What does an RC spur gear do?
How do I choose a spur gear?
Match its pitch to your pinion (such as 48dp or Mod 1), then use the tooth count with the pinion to set your ratio.
When should I replace a spur gear?
Replace it if teeth are chipped, worn or stripped. A damaged spur skips under power and can wreck the pinion too.
