Option 2: ON ( helicopter mode )
than its body diode, so much less heat is dissipated. ESC‟s that
are equipped with active freewheeling are able to operate over a
wider range of throttle percentages due to the more optimized
PWM algorithm that is used. This means that you can run lower
head speeds without having to re-gear or worry about your ESC
blowing up! We strongly recommend you to option Active
Freewheeling ‘On’ as you option the Governor Mode
( helicopter mode )
Page 3
Active FreeWheeling comes in when, instead of running at
partial throttle through the FET body diodes, as one FET
switches off, the “freewheeling” diode switches on to allow the
“freewheeling” current to flow through it instead of it‟s body
diode. Since the resistance of the FET is much much lower

when you option this one, KingKongIII Pro will act as an ESC
without Governor function, ESC‟s governor function will be
taken over to outside FBL system (such as Vbar/mini Vbar/
Skookum/MB/BeastX). in this case, the start type have to be
set with „soft start‟ and only one of Heli mode parameters can
be option is: Spool Up Rate.(see the following screenshot).
External Governor
Kingkong III Pro USER MANUALS www.hifei.com
There are two Governor Modes in Flight Mode, they are: Exter-
nal Governor and Governor.
RPM sensor: KingKongIII Pro has a built-in RPM sensor to
provide the rpm signal to the third Flybarless devices such as
Vbar/mini Vbar / Skookum/BeastX Plus, and the RPM signal
specification as following:
RPM Signal Voltage: 3.3v
RPM Signal Duty Cycle : 50%
Internal Resistance: 510 Ohm
Governor
The Governor mode acts as an RPM control. Throttle stick posi-
tion determines the RPM that the motor runs and the controller
will attempt to hold that RPM regardless of load changes and
battery voltage decreasing . Thanks to Active Freewheeling ,the
motor RPM control could be available as long as the throttle lev-
el exceed 30%. In Governor Mode, the‟ brake‟ MUST always
disable, „Soft Cutoff‟ and „Soft Start‟ MUST be optioned.
Note: we strong recommend to open the Active Freewheeling
when Governor is option
Spool Up Rate indicates the startup spool up rate, the default
setting is Level 3, higher level numbers
means to approach the head speed faster.
Governor Gain The default setting is grade 9, the higher grade
number means the higher gain.
Head Speed Change Rate The default setting is standard, this
setting indicates the change rate between 2 different head speed
switching (for example, throttle curve switch up from Normal to
Idle1 or Idle1 to Idle2 ,vice versa).
The "Head Speed Change Rate" value also determines the speed
at which the head recovers.
AR Recover Time is Autorotation Recover Time, it also can be
understood as the recover time from Autorotation (TH=0) to
Normal mode. The default setting is „Disable‟, it indicates the
AR is inactived.
10 to 60 Secs can be optioned to determine the recover time that
Autorotation is actived, for example if you program the AR Re-
cover Time to 30 secs, the AR will be available WITHIN 30
secs, in this period the motor can be ramped up to a preset head
speed instead of soft startup, but more than this time ( >30 se-
conds) will lead to the motor engaged with soft startup.
Throttle Calculator is a calculator to help you calculation the
throttle curve according to your desired HS, Gear rate and motor
poles. Please see the following screenshot:

* Incorrect gear rate/motor KV probably results the ESC Out-
put haven‟t enough reserve to compensate battery voltage de-
creasing and load change, in the case there is a tab pop out to
indicate „Head Speed Out of Control Range‟. Generally you
can Inc/Dec the tooth of motor pinion or Inc/Dec the Desired
Head Speed to get the best match results. Please carefully
check your heli configuration, make sure the desired heed
speed is under control.
Furthermore, fill out the battery voltage and motor KV can help
you find out the ESC power output match with the pre-set head
speed, HiFei recommends for optimum the ESC output to motor
about 80% power, it ensure the ESC has enough reserve to com-
pensate the battery voltage decreasing and load changing. Please

Trouble-shooting when use V5.0
Q: In process of installation of V5.0, computer pops-up a
box to request for 64 bit driver?
A: After V5.0 is finished installation to PC, back to the di-
rectory folder of HiFei V5.0 from where it is installed, you will
find the driver for 64 bit. Run the driver and finish the installa-
tion by hand. Then computer will notice software can work
normally.
Q: It pops-up box „ Time out, device open failure‟ when
click on „Open Device‟ button.
A: There are three possible reasons to result from this prob-
lem. 1) First is wrong polarity connection between ESC receiv-
er lead and USB linker. Please check if the connection is cor-
rect and tight. In addition, Kingkong III 160A and 200A are
OPTO, it is requested to connect ESC to battery pack when
connect them to PC. 2) Second reason may because ESC were
damaged in running. In this condition, please contact our after
-service for repair. 3) At last, it may because USB Linker is
damaged.
Q: It pops-up box „Invalid Com Port‟ when click on „Open
Device‟ button.
A: It because com port for ESC connection device is wrong
or occupied by other devices. Please open „Device manager‟ of
„My computer‟ to check the right com port number or change
the com port number which be occupied to an available port
number. Then open V5.0, select the right com port number and
save it.
Q: It cannot upload data and pops-up a box „C:\Program
files\V5.0\ xxx cannot be found‟.
A: It because ESC run too short time and the logged data
cannot be showed in window. Please clear the data and fly it
again for a longer time than required minimum time.
Q: In the process of uploading data, it stops uploading and
pops-up an error box „Program: C:\Program Files\Hifei V5.0
\Hifei V5.0.exe This application has requested the Runtime to
terminate it in an unusual way. Please contact the applications
support team for more information.‟
A: The problem is because V5.0 is installed to „C‟ and the
security setting of „C‟ stops the uploading. There are three
ways to solve the problem. 1) First, if PC has more than one
hard partitions, then change to install V5.0 to other hard disks
from “C‟‟. 2) If PC has only one hard disk „C‟, you can try to
install V5.0 to a flash disk. 3) Change security settings of „C‟,
select PC user as „administrator‟ and let all the permissions of
writing and reading below are allowed. Save the change. Then
try to upload data again.
