I am going to run my MBX-6 with the stock gearing. I will be using a Medusa 36-60 2000 along with my Neu 4s 5000mAh packs. What gearing should I use? I was told by Tony Screws to use 16t, does that sound right? I thought I should start with a 15t pinion. Any thoughts? I'd hate to buy 14, 15 and 16 pinions and only use one of them.
