I do not have a Scalex indy car yet so I would also be interested in some comparision.
The following is my experience when taking out the magnets but doing absolutely nothing to the cars otherwise...
My experience of recent F1 and 'Single seaters' is that the F1 ones did not run as well straight out of the box without magnet as the 'single seaters'. The main reasons for this seems to be the tyres. Also the single seaters seem to have better acceleration than the F1 - where the F1 seems to have better top spead. But since the original single seaters have a much better grip they are faster on my track overall. My track has often one long straight and then curves for most of the rest...
As you can see I am focusing on the 'little jonny' variants of experience and 'tests'.
