Installed into a WLToys 144001. everything fit well. be sure to order extra screws and a new engine mount to make things easier. the stock screws are superglued in an very hard to remove. This is much easier to install with new components.

Great motor and ESC. running it in my two 144001 buggies, slightly more power than original, but way better weight balance, and handling. the original shocks and springs are way better suited to this overall weight. I bought the Hobbywing shaft adapter from Banggood to bring the axle diameter up to 5mm and got a 5mm 15t mod 0.7 pinion from somewhere else. That fit the original motor mount perfectly in the smaller holes.

This set fits in my a959 well. It was easy to grind the shaft down to 2mm for the pinion gear with my dremmel. The esc fits on top of the servo and I can fit a 1500 mah 3 cell!

Very good motor an ESC a lot of power and speed! (if you want to put it in an a959 car I recommend to get 3600KV with the 17T pinion, you will have to drill a bigger hole in the pinion)

Received in reasonable time, should work good for my 144001 brushless upgrade!

Perfect for 1/18 scale wltoys a9x9 series I use it on my a979 and fits well using the stock motor seat, motor shaft needs a 3.175 hole of pinion gear, so you need to upgrade or to change you pinion gear to 12428 pinion gear or the feiyue.. additional info. if you want to use other pinion gear and reduction gear better buy also the adjustable motor seat for a9x9 series not for B series.

Fits great! Do NOT run the ESC on 3s. I blew one up. Perfect for 2s. upgrade to a 60a esc if you want to run 3s.
