Problem with esc or motor

[afhogervorst]

I am a new be from the Netherlands who want to speed up his mg. I have bought a leopard 3674 3d 2200kv with a hw seaking 180a. Set up is stock prop and running on 4s turnigy 5800mah 25-35c. With this new setup i can run 3 laps or say 400meters full throttle and than its seems that he is turning into a lipo cut-off. temperature is not above 35 degrees for the esc and the motor at that time above 27 degrees. The lipo's are full 8.3v and when he "cut off" they are 8v. Have anybody any idee what this can be? I think its the motor but.....

I have the same problem as you but with a ul-1 2030 kv motor and a turnigy marine 120 A esc. On 4S, the lipo cut off arrives very quickly although there is still plenty of capacity in the batteries. On 5S, the boat suddenly slows down after one or two accelerations. Have you got any solutions, I desactivated the lipo cut-off but still encounter the same problems, is it a problem of timing ?
