Thats what I was going to do, just use the flux tranny. I sold my x and xl on ebay and am not gonna bother with the hassle and just get a flux and make it an XL. Does the flux tranny have the mounts to put x or xl brakes on it? I really dont want to use the motor as the brakes. Now that I've abandoned my plans for an xl convertion I have a new in the box mamba 2200 combo if anyones interested.
