RE: cool steerig mod for the tamiya mad bull
My issue with it is if you take the inside filter out the screen scraps the dirt off of it and it falls into the opening of the tube and the dirt that was sitting on the out side of the screen falls inside the cage and when you push the filter back in it shoves the dirt into the tube.
I had dirt get into my motor that way, the first day I used it. I've had several people tell me that those filters have smoked there motors. There is no outer filter for the end screen and the end foam on mine was super thin. not much protection.
I went back to the stock filter, have never had it fail. I even oiled the outer filter on the Motor saver.
