Installed this in a DHK Hunter to replace the stock brushed - I just put in an 18 tooth pinion (5mm shaft - remember that when ordering) and used a 120 amp Rc gearbox Esc. This combo is quite a bit faster than the DHK brushless that my son has an ran about 145 ° after a half hour of bashing in very hot weather. It does cog a bit at very low speeds ( nothing terrible) so be aware of that. I think value wise it is hard to touch at this price, especially if you are not a pro racer. I run it on 2s 6500 from VH also, and so far it is a great combo. Thanks again VH! Keep good service and good product ( in stock) and you will continue to grow. (Posted on 6/29/2016)
