Thanks in advance

I haven't run the SPX on any outdoor tracks but from what I have seen and done I don't think you would want to run that fast a motor on TP mode 8.
If you did I would start by gearing down 8-10 teeth and see what happens.
What type of racing are you doing 5cell TC?

Anyone tested the SPX stock spec with any advantages over the TC spec for running 10.5T class? Is it necessary to invest the SPX SS since I already own the TC spec?
Thanks.

We had our local winter series race last weekend. A few drivers had the new SPX speedo.

Class was 13.5 rubber tire, track was carpet 19x12m, so rather small, usual ratios on the Novak motor tended to be 5.4 on the TC. Those with the SPX could gear down further (I think something like 5.8 ish) and still maintain similar speeds. We're all thinking about getting one now, but interestingly TQ for the race was with the old (oringinal!) Sphere, with TC Specs 2-5.

It's the driving and set-up. If everything were equal, i think the SPX will prevail.

Pedro, vou escrever em inglês para que os outros usuários também possam entender.

With 7.4v, rubber tire and 9.5T motor you can start with 6.30~6.50 final ratio, I'm running this configuration at a track with a 40m long straightway and fast flowing asphalt circuit.........

Motor temps are around 90ºC, I'm currently running geared at 6.30........
