Hi Harry, we use the Red Scaleauto on our big Ninco club track;
with magnet : Fly Chevron ( or other similar classic) with 8/9 : 36 gear, slot-it pick up and braids, and also rear axle with bushings : it's a bomb!
And also the Fly Corvette, with rear slot it axle and gears 8 : 29/30 and very small front tyres is a rocket, and also controllable.
Without mag : slot-it Porsche, with sidewinder motor mount; 9/10 : 36 gear and some weight at the rear of the pick up and on the chassis' sides runs very well.
But we all use good controllers, such as Professor motor or Parma modified by NSR, or also NSR electronic and our track has long straights : on a home track with simple controllers I think the scaleauto will be a problem and not a solution.
Ciao
