Thanks for the replies, so my main question is do I need to change the idler gear the SR uses a different idler gear part# than the DC the DC comes with the slipper. So is The Idler gear the same amount of teeth and just a narrower version on the SR for Less spinning resistance and fatter one on the DC for mod motors or is it a different teeth count? thanks guys it would be great if Frank could chime in on this
