So I hate to admit it but, I don't understand gearing. So when a guy posts how his car is geared he will say "I run 23/45." So what is the name of the first gear in those numbers and what is the name of the second? I thought I heard speed and pinion once upon a time. Anyway what happens when those numbers increase or decrease? Can you gain a lot of speed by changing gearing? Just try to explain it your best to someone who is newer to RC's. Video's are always nice if you know of a good one. I'm a visual learner. Thanks for whatever help you can give.
Sincerely, A little Embarrassed (AKA-aricaptainic)
