does not fit non arrma motors. description does not say this either. its well made and the concept is a great idea but it did not fit my CC 1520 or any of my other 5mm shaft motors. shame because there is a distinct lack of 28t 32p/mod.8 pinion gears.
I am a huge fan of the D shaft pinion gears series by ARRMA, both the D5, and the D8. Both are incredibly good gears, and very strong, and stand up much much better than their simple set screw counterparts.

This pinion has worked great in my Senton, even with a small gear, the power is insane. I plan on swapping the pinions when I get more experience handling my Senton 4x4 3S BLX.
Reviewers rate this D-shaft steel 0.8 mod pinion highly for strength and durability compared with set-screw pinions, with two reviews praising the design and performance. One reviewer reports it works well in an Arrma Senton with power described as strong. A 3/5 review, for the 28T variant, reports it does not fit non-Arrma 5mm shaft motors, which the listing did not state. Two of the four reviews appear to be near-identical text, which limits the weight of that praise. Reviews cover several tooth counts, including 15T, 16T, 18T and 28T.
- + Strong, durable steel construction
- + Stands up better than set-screw pinions
