I have not used it with the stock fan, but the fan/motor combo that Don sold me (balanced), is nothing more special than the one you have. not belittling Dons fan by any means............just trying to point out that it's a regular, plastic type fan, just like yours. he just puts them together and balances them silky smooth. his motor with your fan will be just fine, as long as yours is balanced. you could always send him your fan and he can put it together, balance it and send it back. or, do what I did and buy one of his used units. I paid a little more than $40 for the fan, motor and ESC, shipped to my door. I will recommend his products to anyone. super nice guy and an awesome product that he stands behind. you can't beat it for the money.
