I have Hudy truers but the principals are the same. Cut at 0 degrees for the front and .5 degrees of pre-camber in the rear for nitro sedans. If you are running lots of rear camber like 3-4 degrees you may want to step it up to 1 degree.
As for speed, I run mine at full speed all the time. This is "feed speed" we are talking about and the spindle speed is fixed. The only time I might slow the speed if if I am cutting some hard compound front tires like 45+ durometer.
EDIT: Oops, i just realized this was the electric board. Stick with zero degrees of pre-camber.
