slipper heating issues

i find that if i dont keep my slipper screw as tight as possible the slipping causes a tremendous amount of heat to the point where the clutch smokes!

i like the idea of a slipper to cushion the drivetrain. what else have you guys done?

i am running 8xl's +MMM + 6S in my erevo and 4S in my emaxx and similar behavior.
Actually i was running 2 8XL's but smoked one running 6S as i was warned on this forum and have my 2200 castle on order.
