Failsafe Instructions

Standard Range Testing

Advanced Range Testing Using a Flight Log

The AR7100/AR7100R feature two types of failsafe: SmartSafe

and

Preset Failsafe.

SmartSafe

This type of failsafe is recommended for most types of helicopters.

When the transmitter and receiver are turned on the receiver connects

to the transmitter and normal control of all channels occurs. If loss

of signal occurs, SmartSafe drives the throttle servo only to its preset

failsafe position (low throttle) that was set during binding. All other

channels hold their last position. When the signal is regained, the

system immediately (less than 4 ms) regains control.

Preset Failsafe

When the transmitter and receiver are turned on and after the receiver

connects to the transmitter and normal control of all channels occurs,

if loss of signal occurs preset failsafe drives all servos to their preset

failsafe positions. Some pilots prefer this method but normally

SmartSafe is recommended for helicopters. When the signal is

regained, the system immediately (less than 4 ms) regains control.

Programming SmartSafe

During the binding process the bind plug is left in throughout the

process and is removed only after the receiver connects to the

transmitter. After the connection is made, confirmed by operating

the servos, the bind plug can be removed. The receiver is now

programmed for SmartSafe.

Programming Preset Failsafe

During the binding process the bind plug is inserted in the bind

port, and then the receiver is powered up. The LEDs in each receiver

should blink, indicating that the receiver is in bind mode. Now before

binding the receiver to the transmitter and with the receiver in bind

mode, remove the bind plug. The LEDs will continue to blink. With

the control sticks and switches in the desired failsafe positions, bind

the transmitter to the receiver by putting the transmitter/module into

bind mode. The system should connect in less than 15 seconds. The

receiver is now programmed for preset failsafe.

Note: Failsafe positions are stored via the stick and switch positions

on the transmitter during binding.

Before each flying session, and especially with a new model, it’s

important to perform a range check. All Spektrum aircraft transmitters

incorporate a range testing system which reduces the output power,

allowing a range check.

Range Testing

1. With the model resting on the ground, stand 30 paces (approx. 90

feet) away from the model.

2. Face the model with the transmitter in your normal flying position

and put your transmitter into range test mode. This causes reduced

power output from the transmitter.

3. You should have total control of the model while in range check

mode at 30 paces (90 feet).

4. If control issues exist, call the Horizon Product Support

department at 1-877-504-0233 for further assistance.

The following advanced range check will confirm that internal and

remote receivers are operating optimally and that the installation

(position of the receivers) is optimized for the specific aircraft. This

Advanced Range Check allows the RF performance of each receiver to

be evaluated and to optimize the locations of each individual remote

receiver.

Advanced Range Testing

1 Plug a Flight Log (SPM9540 - optional) into the data port in the

AR7100 and turn on the system (Tx and Rx).

2. Advance the Flight Log until F- frame losses are displayed by

pressing the button on the Flight Log.

3. Have a helper hold your helicopter while he observes the Flight

Log data.

4. Standing 30 paces away from the helicopter, face the model

with the transmitter in your normal flying position and put your

transmitter into range test mode. This causes reduced power

output from the transmitter.

5. Have your helper position the model in various orientations (nose

up, nose down, nose toward the Tx, nose away from the Tx, etc.),

while your helper watches the Flight Log noting any correlation

between the aircraft’s orientation and frame losses. Do this for 1

minute. The timer on the transmitter can be used here.

Press and hold the bind button
