Hey guys, I'd like some help with 4s lipo. I will be using two Gens Ace 2s 5000 mah 40c lipos. I am thinking of using a 21/54 setup. I've done a lot of research about this setup and many people seems to be satisfied with that setup. However I'd like to go to the extreme and use a mod 1 gear. I don't understand what mod 1 gear is but there's a video of the ERBE on youtube reaching 72 mph speeds with that gearing on 4s lipos. The guy used a 25t 34t mod1 gear setup to attain that speed. What will my temperatures be if I use that gearing (25t 34t mod 1)? Will this affect my motor and ESC? I'd like a little bit of information about mod 1 pinion gearing. Thanks guys.
