ESC PROGRAMMING and FAILSAFE

TECHNICAL NOTICE

FAILSAFE SETTING

IMPORTANT: Before installing the propeller, it’s

important for safety reasons to ensure that the

failsafe on the receiver is at the 0% throttle preset

position as indicated in the instructions below.

1. Install the AA batteries into the transmitter.

2. Make sure the throttle

stick is in the minimum

position or 0% throttle.

3. Make sure the servo

reversing switch for

CH3 Throttle (located

on the front of the

transmitter) is in the

“R” position.

4. Power on the transmitter.

5. Plug in the battery to

the aircraft.

6. Press the LINK button

on the TR624 receiver

and hold for 2 seconds.

The red LINK light should

blink and then stay on.

The failsafe is now set. In

the event that the receiver

loses signal from the transmitter the throttle will revert to 0%.

If you would like to set the failsafe to a different position, refer

Throttle stick is in

the minimum position!

to the instructions below. Always remove the propeller

from the aircraft before adjusting the failsafe.

FAILSAFE FUNCTION

The included Tactic TR624 receiver has a failsafe feature

which engages in the event that the radio signal from the

transmitter is interrupted. If radio contact is broken, this safety

feature causes the servos to automatically move either to

a certain position, or hold their last position to prevent the

model from moving in an erratic manner. Channels 1, 2, 4,

5, and 6 will enter a “hold” mode, whereby the servos will

lock in their last recognized position.

The servo or ESC connected to Channel 3, normally being

the throttle control, will move to a pre-set position. The

factory default failsafe position for Channel 3 is to move

to 0% throttle. Motor/prop movement should stop if the

receiver loses signal from the transmitter. The throttle

servo’s failsafe position can be manually re-set to any other

position if desired, as follows:

IMPORTANT NOTE: Before manually resetting the failsafe,

make sure the servo reversing switches are in the correct

position for the application and the propeller is removed.

1. Apply power to the Tx and Rx.

2a. If using an ESC, do NOT arm the ESC. Do NOT attempt to

adjust the throttle’s failsafe position if the ESC is armed.

2b. If using a gas or glow powered engine, do NOT attempt

to adjust the throttle’s failsafe position while the engine

is operating.

3. Move the Tx throttle stick to the desired position for the

throttle control to move if the Rx goes to failsafe.

4. Press and hold the LINK button on the receiver, and the

Rx’s LED should blink twice. Release the LINK button,

and the receiver’s LED should turn on (stop ashing). The

Tx and Rx should now be linked, with the throttle failsafe

in the new position as set above.

NOTE: If you replace the ESC with a different ESC which

has a signal loss feature, the pre-set failsafe position is

irrelevant as the signal loss feature will cease the throttle

operation if the signal is lost.

OPERATION / STARTUP

1. When powering up the model to run the motor or y,

always lower the throttle stick and turn on the transmitter

rst before connecting the battery to the ESC (similarly,

always disconnect the battery from the ESC before turning

off the transmitter).

2. Always securely hold onto the model when connecting the

battery. Holding the model and expecting the propeller

to turn will prevent an accident or injury.

Each time you connect the battery to the aircraft, the ESC

will send electrical pulses to the motor causing it to chime

three times (“1 2 3”) followed by a single, longer beep

(“beeep”), followed by either one or two more short beeps

depending on whether the brake is On or Off (more on the

motor brake below). Now the model is ready to y and the

propeller will turn when the throttle is advanced.

If the transmitter is not turned On before the battery and

ESC are connected (so the receiver is not receiving a signal)

the motor will still chime three times (“1 2 3”), but then will

sound consecutive beeps (“beep,” “beep,” “beep,”….) until

the transmitter is turned On, at which time it will resume the

starting sequence of the single, long beep (“beeep”) and

one or two short beeps.

If the throttle stick is not all the way down when the battery is

connected to the ESC, the motor will beep rapidly (“beep, beep,

beep, beep, beep…”) until either the battery is disconnected

or the throttle stick is returned to the Off position. Then the

normal beep sequence will resume.

If the chime sounds followed by continuous, slow beeps

(“beep…beep…beep…beep…”), then the receiver is not

receiving a signal from the transmitter. You may need to

link the receiver to the transmitter, or check the connection

between the ESC and the receiver.

THROTTLE CALIBRATION

If you connect the battery to the ESC and hear the three

chimes (“1 2 3”), but then the motor beeps rapidly (beep,

beep, beep, beep, beep, beep….) and does not run when

you move the throttle stick, the ESC is not detecting the

end points of the throttle stick and requires calibration.

Recalibration may also be required if you ever switch to

a different transmitter, or if you adjust the throttle trim or

throttle end points in your transmitter:

1. Remove the propeller.

2. Turn on the transmitter and advance the throttle to the

“up” position.

3. Connect the battery to the ESC and hear the chime

followed by two long beeps (“beeep, beeep”) indicating

that the ESC has read the top of the throttle range.

4. Move the throttle stick to the low position and again hear

a single long beep (“beeep”) (signaling that the ESC has

read the bottom end of the throttle range) followed by

one or two short beeps signaling the completion of the

procedure. Now the throttle has been calibrated.

Note: If this recalibration does not work, increase or decrease

and repeat the procedure.

BRAKE SETTING

The ESC is preset from the factory with the motor brake off,

but if you inadvertently turn on the brake, or if the ESC was

not set correctly, follow these instructions to turn On or Off

the brake:

1. Remove the propeller.

2. Turn on the transmitter and move the throttle stick all the

way up.

3. Connect a battery to the ESC to power up the ESC

and radio.

A. Hear the chimes (“1 2 3”) followed by two long

beeps (“beeep, beeep”) followed by a pause, a short

beep (“beep”), another pause, then two more short

beeps (“beep, beep”).

B. If you do nothing, the brake will not be changed.

Disconnect the battery from the ESC.

C. To change the brake setting (on or off) reconnect the

battery to the ESC with the transmitter on and the

throttle stick all the way up. Lower the throttle stick

after the single short beep to turn the brake off; or

lower the throttle stick after the two short beeps to

turn the brake on:

D. After the throttle stick is lowered to turn the brake

followed by a single short beep (brake off) or two

short beeps (brake on) depending on how you just

programmed the brake.
