4. The system will connect within a few seconds. Verify that all remote receivers’

LEDs are glowing solid, indicating the system has been bound and is ready to

use.

Teach Failsafe

In the Teach Failsafe sub menu, the failsafe

positions are stored. In the event of a signal loss,

all servos will be driven to the position set.
Preset Failsafe allows you to set the specific

control positions for all channels to return to

should a signal loss in flight occur or at any other

time a successful connection has been made.

The Preset Failsafe is typically used to prevent “fly aways” in high-performance

models by deploying spoilers in sailplanes or putting gas- and glow-powered

models into a slight turn at reduced throttle.
To program the failsafe channel positions, follow these steps:
1. Move all transmitter sticks, switches and pots to the desired failsafe positions,

typically to low throttle and centered controls. Set the positions as desired for

your model.

2. Press the SET button with the cursor next to Teach Failsafe.

3. All positions will automatically be stored and ready to use.

Frame Rate

Frame rate indicates the time interval at which

the servo signal is refreshed. Many analog

servos are not compatible with higher frame

rates. For many analog servos, it will be

necessary to select the 21ms setting.
NOTICE: Set this rate to your servo’s operating

rate or damage to your servos can result. For operating rates, refer to your servo

manufacturer’s documentation.
A faster refresh rate causes the servos to respond faster and will offer greater

effective torque because they are better able to counteract the forces acting on

them. The frame rate setting should only be changed if you know that your servos

are suitable for the frame rate you wish to use.
The frame rate adjustment is only available for the four dual-matched channels and

the sequencer output channels. All other channels operate at the same frame rate

as the cockpit.
To select the Frame Rate, complete the following steps:
1. After entering the Frame Rate function with the SET button on the SensorSwitch,

press the I or II buttons on the SensorSwitch to select the desired frame rate.

2. The frame rate is available for the following values:

12, 15, 18 and 21ms

3. After making the desired selection, press the SET button on the SensorSwitch to

confirm the selection.
