Product Description

This product will now be replaced by the CarbonBird™ ESC 40a - same item with direct to us in AU return warranty  (no longer has to be sent to HongKong)

HobbyWing 40A ESC are made for MultiCopters - with full house connectors pre-installed - specifically wiithout a BEC - OPTO - less EMI in the multicopter frame and less heat -  you get a lot of electrical noise from 6 or 8 high amp uBECs in a radial pattern at the centre of your multicopter - The 40A Optos are well cooled with full 40Amp 6S rating - burst of 55A for 10 secs -  very smooth throttle curve and good quality silicon wires and Large Capacitor.  Best of all they output a massive 1008w on 6S (25.2v/55amps for 10 secs =>1300w) when needed with 2 x large Caps ; Plug-n-play JST on DC side and pre-fitted 2.0mm Female GBC on extra long 135mm three phase wires - fully RoHS - Flight tested with MultiWiicopter code - NAZA and Wookong - they are both 400 and 490hz compatible.

Features / Specifications

  •        Reset:  reset  all  the programmable items to their default settings
  • Protection Features: Low voltage cutoff protection / Over-heat protection / Throttle signal lost protection


  • Military standard capacitor of extreme low resistance increases the ability of prevention of unwanted RF noise during flying.
  • Extreme low resistance PCB is helpful for getting a super current endurance capability.
  • Microprocessor uses separate voltage regulator IC, with good anti-jamming capability.
  • Program with stick banging or ; with Hobbywing's Program Card (not included)
  • 90 day return to factory (HobbyWing HK) warranty* Excludes misuse/over voltage/reverse voltage/over amp/short circuit or motor fault - see below

Important beginner NOTES on ESC set up :  Read this before connecting any ESC !!

  • DO not connect the ESC back to front - ie reverse polarity - You will smoke it!
  • Make sure to solder all ESC wires with Flux Paste (Not flux core solder) - a bad connection (a loose fitting connector)  or dry solder joint(no flux) - will cause the ESC to burn/fail and the motor to possibly burn as well.  Check all wiring with a DMM first.
  • Use gold connectors and extra long banana plugs - do not trust factory installed banana plugs on cheapo brushless motors - remove the heat shrink on any cheapo Hobby clone Motors or rc-timer junk motors (or any clone) and remake the joint  properly using flux paste.
  • During first throttle up power check - concentrate - if the motor hesitates or stutters - or the prop twitches back and forth - IMMEDIATELY cut power (throttle OFF) - investigate for a broken wire in the motor - a shorted wire in the motor (mounting screw ruptured the windings) - a shorted connector or insulation cut  - or anything blocking the motor from turning (a screw from your work bench trapped inside on the magnets).
  • to reverse the direction of rotation of a brushless motor exchange any 2 of the 3 motor wires
  • Use a power meter to ensure you are not overloading the ESC at WOT (full throttle for the prop) - ESC works hardest at mid throttle - so it's useless to think that if you don't fly full throttle you won't overheat the MOSFET because you are not using all the amps - completely opposite - the ESC will overheat if the kv of the motor is too high for the props used.  You must do a WOT check and make SURE at full throttle the MAX amps are 55amps or less !!!!!
  • For MultiCopters - Use an external switching uBEC - after throttle calibration of the Tx range 1095/1500mid/1905 and also the ESC learning curve - then remove the red wires and apply heat shrink.
