chris202 When I ordered this gear I did notice it did not come with the grub screw but figured it would be a common size. Well, Ive been looking for the correct size now for about 12 hours now. I think its a M4, but Im not sure about the threads. I have M4 but they don't fit. I guess I'll bring to the hobby shop see if they can help. It is not a common m3 like in a L202, A959. Just letting everybody know to make sure they have grub screws before ordering this gear. Awesome shipping thanks Banggood !

chris202 The motor is not faster, but it does have more torque and power. It will spin the tires almost all the way to top speed, which is fun with slicks. Next I will try the 5000kv. This motor is awesome if you are looking for torque.

chris202 So you just received your axles? UUUUmmm that's weird they are out of stock and have been for months. I ordered mine on Aug 30. And the order is still back ordered, lets be honest with our reviews please.
