You could do it on 2s, But it would be better to go 3s and gear down for 40. less heat and stress etc.

Is there any way to determine what you should have for a gear ratio? Ive seen the fomulia to get what you have BUT what should you aim for?
Like i currently have a 3s 4x4( Acme Raptor) The origional motor was undersized but it was a rocket! Now i have a 13.5T, Much bigger motor with a 23t pinion and it was alot slower. And got real hot!
