V3.0 esc
When i first installed my hobbywing v3.0 in my 4wd together with lrp x20 5.5t, after a few laps the esc would just go into a kind of limp mode and not produce the top speed that it should.
Was told by a fellow racer that you needed to disable the voltage cut-off as thev3.0 are known to produce the symptoms that you describe if you have it set to 3.2 or even 3.0volts.
Disabled it and has been fine ever since.
As long as you know your lipos are fully charged, a 5 minute heat will only take about 2000mah out of the battery so you are in no danger of damaging it.
I think the reason why the esc drops the top speed is that at some point in the race the battery's are under heavy load when applying full throttle and the voltage drops and that in turn kicks in the voltage cut off.
Try disabling the voltage cut off and the thermal cut off but check the motor temps and see if it solves the issue.
