It certainly is VERY quick. Ive not timed any laps but it certainly feels quicker than some of the ScaleAuto race chassis cars I have - and definitely quicker than its sister race series car, which I comprehensively 'improved worse' yesterday 

I guess that'll be partly down to the simpler chassis making the home series car quite a bit lighter. (Thinks. Must weigh them both.)

Nope, I have mine weighted, and it has less power than the big boxer angle-winder in the race series anyway - a little over half the actual wattage.
But a sidewinder in a fixed chassis, if set up well, can be as quick as a podded sidewinder car on a smooth track.
And they are simply very tractable. You can get the power down quickly out of a corner.
I did a review and tune article on the ScaleAuto 991 HS and Race series here a while back. Maybe worth a read for tuning tips.
