Hi,

I am upgrading my maisto rock crawler extreme but seem to have lost one of the double spur gears in the rear gearbox. Actually there is a similar sized gear at the front as well. The spur gear is a reduction from 40 teeth to 10 teeth. Outer diameter for large wheel is 25mm while the smaller one is 9 mm. I have been searching online for about 2 weeks and although I have found all sizes of gears I cannot seem to find one that fits the above.

I have looked in eBay, rc shops and Ali express without any luck. Seems to be some custom size made for maisto.

Any help will be appreciated.

Perhaps you could connect 2 gears.

Or buy a defective (anywhere else but that gear) second crawler for very cheap.

3D printing might be possible, but likely on the edge of accuracy and durability, while being quite expensive in relation to the whole thing.
