which motor for speed on 3s lipo

Well, also remember you are comparing a 380 motor vs a 540 motor (though it has a 480 sized rotor). Either way, its still a larger motor. And even if the KV ratings were the same, the Mamba Max Motor would have more torque since its a 540 and could be geared higher because of it.

However, the Mamba Max motor also has more KV as well, so the Mamba Max will definitely be faster than the Feigao motor.

i couldnt agree more i feel i made a good decision going with the 5700 for 3s and putting the fiegeo away cause i got the need for speed i did a lot of reasearch before ordering the motor but am sure it will do me better than my fiegeo

I disagree on the gearing issue. I think you can actually gear a 380C 6L more agressively then the MM 5700 with better results. The longer rotor, albeit maybe a tiny bit smaller diameter more than makes up for the torque...even moreso given the lower kv of the 6L.

However, for just doing speed runs, I don't think I'd buy either. I'd drop the $ for a Lehner.

FWIW, the 6L is no slouch of a motor...I'm running it real close to 50MPH in my T3 (gps verified at 47.7mph) with only using a 2S lipo. The problem I have is keeping the rolling wheelies to a minimum with all that torque.

i have the fiegeo now and am happy with the speeds im getting but hear of more speed with the mamba 5700 and i also hear the mamba is more efficient so i bought one and will compare motors and see which one i like more and just keep the one i dont like as much as a spare.

You should easily get more speed out of the MM, just due to being able to go to 3S. The MM are decent motors, but I think too many discount the Feigao as inferior when they do perform extremely well.

yea and the torque is amazing even on 6 cells with the fiegeo. did u see my video?
