have u solve the problem after replacing a new ESC? I have same issue with my esc, one is hot and the other 3 are cool...I have done a flight test but unfortunately crash, when it start to hover above 1/2 inch, suddenly it flips to one side and crash 1 prop...I tried to search solution and fix it before 2nd test flight...anyone have this kind of problem, pls let me know how you solve it...many thanks
i'm getting a similar issue with my 500x. on some occasions motor 1 will stop working all together on other occasions it takes longer or shorter to get up to speed. i believe the heat is pry because the others are working harder to compensate.
after much experimenting i have decided the issue is the speed controller. all 4 motors seem to be fine. i'm ordering a new ESC for motor one in hopes that that fixes the issue. i'll let you know if that solves the issue.
Is the red cabel from the esc's connected to the main board? It ahould only be one, change esc's they are probably all gone. Check battery cells

Changed all the ESC's, motors and used 4 different batteries. Also changed the GU-INS control unit. Problem still the same.
One guy is using seperate BEC and also have the same problems...
Any more suggestions?
