Last night we were doing some racing on my home track with a couple of SCX cars, an IMSA F40 (Alesi) and an IMSA Audi (Stuck). They are non magnet cars with the standard SCX motor, i.e. mild. We ended up almost setting the track record for non magnet cars on my track, 50ft sport with 10ft straight. The fastest non mag car I have is a Fly Saleen racing version, but the SCX cars ran within .1 seconds of it last night!? This was about half a second faster than the previous best for these cars. This is making me believe in the practice of de-tuning cars with NC-1 motors and the like. They are much easier to control and flirt with the edge, without stepping over.
