Absolutely, and they deal with being over/under geared better too. If you look around abit you will see that everyone who uses a neu/quark 125b combo only says good things. Bear in mind the quark has heat issues itself though, but they arent as noticeable when using it with a neu.
I have a Aveox in my truck now and everything is good. I have the 1412 Aveox, but I don't know what winding it is. It is in fact faster than that 2600rpm/V motor that went bad, even with a 13T pinion instead of the 15T I had previously.
I forgot to mention that the 2600rpm/v motor is garbage. I will probably try and my a custom motor out of it. I have some crazy idea cooking up in my head. I'll basically save the can.
