    4s battery on stock motor

    My stock esc died just after 5 packs on 3s. I replaced the stock esc with a 30a esc that can handle 4s. Would the stock motor be able to handle the 4s?

      Ran a 4s 850 mah batt today. It so fast compared to the 3s. It was almost boring to run 3s. Only ran it for 3 mins. Motor temp after the run was 95f and esc was around 90f. I only ran the 4s once and 3s another 7 runs back to back to torture test the esc and motor.

          I'm using a modified 30a Hobbywing aircraft esc. Basically I took the cooling pipe off the original esc and jb weld it onto the hobbywing and re-shrink it. I also jb weld the cooling pipe that is ziptied on the motormount. Almost forgot to mention that I silicone sealed the esc.

              No issues so far. The highest temp I got from the esc is 97f. The only problem I've had was all three hobbyking 4s batt puffed. I''m not sure if that due to age though. My run time on 4s 850mah is only 2 mins then slows down.
