jesus.... 5700kv on 3s..... my first thought...... check manufactures specs of that motor and ESC with relation to there watt limit
if you are using a combo like Hobbywing ezrun 35a combo id really advice against it.
5700kv is not for 3s.... thats over 60,000rpm... and with the torque these motors have... it will be so slow because it cant get traction and is impossible to drive...
i built this for giggles and ended up selling it before it destroyed it self.... but this thing was impossible to drive in a straight line.... and it was only 4300kv on 2s
