The previous MGB Scalex released (rally car 83) didn't have a de-tuned FF but it is the same zoomer in all the other saloons they make. Personally if you run one of these on a non-mag track I recommend the motor Mark has from the Derby City racers. Very drivable.
I would also like to know Dr Diff's question. But I'd bet they are using the zoomer.
I also wonder about those black bumpers. Anyway, if you're not into fancy boxes for your shelf, Scaley is due shortly to release their light blue No. 48 Sebring MGB.
