Canadian RC guyVerified owneron Hot Racing Arrma 6S Hardened Steel Mod 1 Spur Gear (50T)

This is an excellent hard steel gear, light weight for its size, will allow for a max pinion gear size of 25 teeth with stock motor mount. Very high end looking final product.

I've been using hot racing for many years. I was not aware this does not fit the Kraton EXB. Besides this, quality looks to be the same as many other HR parts. I am not able to testtherefore I cannot speak on usage nor how it will hold up at this time. However I will keep it for future use.

Was good first half dozen runs and had smooth gear mashing then four teeth broke off very disappointing for a spur gear that cost $30!!!

What reviewers say

Three verified owners reviewed this 50-tooth hardened steel Mod 1 spur gear for Arrma 6S. One reviewer praised its strength-to-weight, high-end appearance, and fit with a 25-tooth pinion on the stock motor mount. Another, an experienced Hot Racing user, reported that it does not fit the Kraton EXB and judged build quality similar to other Hot Racing parts, but had not yet run it. A third reported that after several smooth runs, four teeth broke off, and called the price disappointing. Reviewers do not agree on overall durability, and only one reports actual use, which ended in tooth failure.

  • + Hardened steel construction
  • + Light weight for its size
  • + Premium appearance
  • + Fits 25T pinion with stock motor mount
  • − Four teeth broke after a few runs
  • − Does not fit Kraton EXB
  • − Price seen as high for durability
