Ambient Temperature: 0℃- 50℃
Weigh: 40 g
Size: 45 x30 x 15 (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 our ESC
Programming Card.
zLow-voltage soft-cutoff 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
gearboxes.
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 music when all
the setting is ready to go.

Operation Produce:
1. Choose right Battery voltage range according to
LETON 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. LETON ESC has program card setting or manual
setting function
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. can be used for both fixed-wing aircraft or helicopter
models
8. LETON ESC has factor programmed for soft start
function.
9. ESC has start and over heat protection function.
10. 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 low 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 point, then connect battery to LETON
ESC, 2 short “B-B” will be heard from the
brushless motor, then remove the stick to the
low 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 LETON ESC. Wait until 3 short
“B-B-B” be heard from the brushless motor,
removing the stick to the low 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 ESC. Wait until 4 short “B-B-B-B” be heard
from the brushless motor, then by removing the
stick to the low end. When the setting is ready a
melody will be heard.
2. Program card setting: setting up by program card.
