Kevin you need to change that sigline to Sold....
As for gearing 2 years ago for TCS the number between the magic smoke and no magic smoke was around 5.5 if I remember correct.
Slide for a recommendation for your track not sure but I would gear down bsed on howw much smaller your local track is compared to Tamiya America. I know Canadian TCS runs a mandated 5.7-5.8 max gear ratio.
