I had a Castle Sv3 and 1410 3800kv combo 18/54 gearing which is great but I was lookin for a lil more power and speed. I swapped to an 1/8 scale Tacon 3674 540xl 2800kv and geared it 20/54 and it's seemingly not as fast maybe a little more torque but not what I was hoping for. I'm running both on 3s. Any input? I really thought the 540xl would pack more punch.
