[revo2200kv]

Hello fellow RCers whats up? This is my first brushless setup. And I am disappointed in performance or am I doing something wrong? My first run is using 3s zippyflight max 5000mah pack. Gearing 17/38. Acceleration sucked and so did top speed. So I tried 6s and not much gain in performance. I went to 15/38....and the same result. Using Castle Creations 2200kv motor and HK 150a esc. I used a programming card to set everything that should give me mad acceleration and max throttle. I am using a Hyperion 1420i charger. How do I know my batteries are fully charged? Any and all input will be appreciated.
