Hi all looking for a motor upgrade for my jae 21 . At present im using a Leopard 3674 2200 kv with a Seaking 180 V3 esc with 6mm plugs with blue Turnigy 4s 5000 mah 40c lipo's giving me a speed of 64mph. I would to prefer to stay away from a Nue since im just running for fun . What motor brand and KV would be a possible for a upgrade to sqeeze a little more speed that would fit the original aluminum motor mount ? Regards Andris Golts.
