All caps comes across as yelling.
A reasonable start, I think, would be 45 pinion, 100 spur. The example I found was for the tamiya track. 4.22 overall ratio http://site.petitrc.com/reglages/xra...USA2018052427/ |
might help find combination. Pay no attention to the highlighted red. Just what I was trying at completely different track. But the chart helps. |
https://cimg9.ibsrv.net/gimg/www.rct...7ebd49830e.png Should help with combination. Though some at the track will have better ideas |
Speedworld has a Facebook page. They answer questions pretty quickly.

your best bet would be to ask the ones that race at the track
