ESC 45A-H (High Voltage) Electronic Speed Controller
Thanks for choosing this ESC (Electronic Speed Controller) for your brushless motors. This is a user-friendly, easy
to setup, and high efficiency speed controller for both fix-wing airplanes & helicopters. It is produced by the highest
quality and reliability. We hope it provides you with hours of enjoyment.
We strongly recommend you pay careful attention to the following instructions and warning before you start
using this electronic speed controller.
Model : ESC 45 A-H Connection Diagram :

OVP, Over Voltage (battery) Protection.
LVP, Low Voltage Protection (soft cut-off).
BEC Current: 3A（Max.）.
Ambient Temperature: 0℃- 50℃.
Weigh: 48 g.
Size: 70 x 27 x 14 (mm).
Features:
zHigh rate (8 KHz) switching (PWM); Supported
highest motor speed: 210000 RPM (2 poles), 70000
RPM (6 poles), 35000 RPM (12 poles).
zDynamic braking ensures prompt prop folding.
zOver Heat Protection.(OHP).
zUser easily Programmable ESC Features by ESC
Programming Card (optional).
zLow-voltage soft cut-off protection, cause throttle
going slow down.
zBattery range protection, when the voltage of the
battery pack is lower/higher than the Battery range
threshold, the alarm status is activated.
zBrake / No-Brake operation. Stop folding props cold
or let fixed props freewheel.
zSafe “power on” arming program ensures motor will
not accidentally turn on.
zLow torque “soft start” prevents damage to fragile
gear boxes.
zAuto shut down in 2sec. after when RX signal is lost
or radio interference becomes severe.
zThrottle Range can be auto setting during at first
power on time.
zESC can make brushless motor play a music when
all the setting is ready to go.
Operation Produce:
1. Choose right Battery voltage range according to
ESC input range.
2. Automatic throttle adjustment for using on every
transmitter.
3. Setting Brake or Non-brake mode.

The following setting needs programming card :
4. This ESC has program card setting or manual setting
functions.
5. Setting right battery type, Li-xx or NICD/NIHM
battery. For Low Voltage Protection (LVP) function.
When battery voltage drops to the LVP level, the
motor output decreased gradually instead of a
sudden-stop. This low voltage battery warning
function allows an early safe landing on R/C aircraft.
6. 8 selectable “ready to go” melody.
7. This ESC has factor programmed for soft start
function.
8. This ESC has start and over heat protection function.
9. The motor will decrease its power to full stop if the
receiver is out of the control range. Back to the
receiving range the motor power will be resumed.
ATTENTION: In field use, switch-on the transmitter and
always make sure that the throttle is on the lowest end
before connecting the battery. The controller will
detect battery voltage once the battery is connected.
Instruction:
1. Manual setting:
A. Throttle range setting: move the throttle stick to
the top end, then connect battery to this ESC, 2
short “B-B” will be heard from the brushless
motor, then remove the stick to the lowest end.
When the setting is ready a melody will be
heard.
B. Non-Brake setting: switch-on transmitter and
moving the stick to the top end then connect the
battery to this ESC. Wait until 3 short “B-B-B”
be heard from the brushless motor, removing
the stick to the lowest end. When the setting is
ready a melody will be heard.
C. Brake setting: switch-on the transmitter and
move the stick to the top end. Connect battery
to this ESC. Wait until 4 short “B-B-B-B” be
heard from the brushless motor, then by
removing the stick to the lowest end. When the
setting is ready a melody will be heard.
2. Program card setting: setting up by program card.
(for more detail please read the program card
instruction).
