A special note to gear purchasers for non-model aircraft purposes. We get many inquiry's asking if these gears will fit a Child's X-G-Wiz-Go toy or will repair a home kitchen device or etc. We are model aircraft experts, if it's a model aircraft gearbox, we can help figure out the part on the phone if your stuck. If it's a toy or special project outside the hobby, I can't begin to guess if our gear will mesh with your gear in your device. I can't tell from a photo what pitch your gear is. If your trying to fix a special item, my best suggestion is to purchase all the gears that look similar and have a go at it. Most gears are a few dollars or less.
