Spur pinion combos?

[Patrick]

I'm not really sure how fast it is.
With 12 cells on the 7xl and 51t/13t gearing it's a bit faster than 14 cells on titan's with 66t/20t (Traxxas says 30mph with 66/18 and 14 cells I think), but with better acceleration. 13t pinion is a little bit too small on 12 cells imo.
14 cells on the 7xl is noticably faster than 12 cells, couldn't say how much though. 51t/13t seems ok on 14 cells for my track. But I'd like to try a 14t when I can get one, and when I get my new Quark. Other one burnt out last week. It was 2 weeks old.
