Wow. What a huge difference over the stock pinion gear. I was wondering why my new motor seemed pedestrian and a little slow. I installed this gear and holy hell. I can hardly control it. I may rethink the 11.1v battery upgrade. This this is so fast with a 7.4v. I promptly broke two suspension parts on my first run. Great upgrade for speed. Be prepared for other upgrades because you will start breaking stuff at these speeds. So much fun.
