I'm not Tom, but I've had both. I can't tell much difference between the brushed and brushless power-wise running the 12X6 on 3S lipos, but running the 12X6 I went through 3 motors in pretty rapid succession. I was always worried that at any time my motor might smoke. Then with the brushless, I just fly! I was running a Razor 300, that was too high a Kv motor and it really sucked the juice, that's why I went to the 11X6. Now I'm running a $52 Himax 2015 4100 brushless and the 12X6 and get 20 minutes of hard 3D action on a pack, no smoke, and grins ear to ear. This is basically equivalent to a Razor 350. I would have bought a Razor 350, or a Hacker 20 22S, but both were out of stock. So I tried the Himax and have finally found what I think is the perfect motor. I also have a Razor 400, but haven't tried it since I got the Himax. The Himax doesn't have to "wow" factor of the $90 Razor or the $100 Hacker, but it fits my needs. Love it. Tried to get Gator to buy one, don't know if he did..I think Ulf might have.
