ESC and motor
Clean connector terminals or
replace connectors
Burnt motor coils
Replace motor
Poor soldered connections(dry
joints)
Re-solder the cable connections
The battery pack voltage exceeds
the acceptable range.
Replace with a freshly charged

route of the receiver’s aerial and
ESC cables to ensure there is
adequate separation to prevent RF
interference.
Install a ferrite ring on the ESC’s
throttle cable.
Battery Pack voltage has reached
the Low Voltage Protection
threshold.
Land the model immediately and
replace the battery pack.
Possible bad cable connection
Check and verify the integrity of
