as I burned second ESC I decided to ask for help.
I bought this kit F450:
The Remote Control FlySky FS i6.
The battery is 4s 1800mAh 75C very similar to this one:
I’m not sure that I was able to calibrate the ESCs, but after the calibration, I applied a little throttle. There was a spark in one of the motors and the connected ESC get into fire. I disconnected the battery. The motor was noticeably harder to spin compared to other motors.
I bought another ESC (which is the same model except the connectors are different, is this a priblem?) and motor. I replaced them and added a fuse for 30A (not sure that this is reasonable, but decided to try). Again the same thing happened on another ESC. The ESC again burned immediately like 0,2sec after the throttle is applied. Please help me what can be wrong? I’m thinking that this 2212 motor may not support the 4s battery, but I believe that it should not burn so fast and maybe spin for few mins before getting overheated.
