Kobobek- Not sure but I think Foams and I were discussing this a page or so ago. It was more about how to lay the servo down on the chassis plate for increased steering. I think Foams may have mentioned how you could use a standard servo but you may have to check over the last few pages or so. My advise if you have to use a standard servo is to use the CRC Adjustable Mounts so that you can widen the mounts to fit the larger servo if the stock mounts won't allow the servo to sit between them. Then put the servo in front of the blocks so that you have more room for the larger servo. This will probably mean that you have to mount the ball stud on the back of the servo saver so make sure you get full lock to lock turning radius. Hope this helps.-Dave Arnold
