For typical flight pack installation in a standard 4-channel trainer type your convenience, we have included the photograph below outlining a model airplane. Fuselage Servo, Receiver, Battery Installation Aileron (Wing) Servo Installation 9.1 INSTALLATION SUGGESTIONS It is important to correctly install the radio system in your model. 4. With the servo at neutral, install the required servo arm/horn Please read and carefully follow the suggestions listed below: exactly 90 degrees to the servo case as shown in the diagram below. 1. For added protection, wrap the receiver and the receiver NiCad in foam rubber that is at least 1/4" thick. 5. Before installing the servo output arms, make sure the servo is in its neutral position. 2. Run the receiver antenna through the fuselage and make sure it is fully extended. Never cut or bundle your receiver antenna — 6. All servos must be able to move freely over the full range of their this will decrease range and performance. travel. Make sure the linkages do not impede servo travel. A stalled servo will drain the battery pack within a few minutes. 3. Rubber servo grommets are included with your radio system and should be installed in the servo flanges. The servos should then be 7.

9.3 ADJUSTING CONTROL SURFACE TRAVEL The final step in your flight pack installation will be to determine the more quickly from your flight pack battery, thereby reducing your amount each control surface will move on your model at full transmit- usable flying time. Fortunately, servo “stalling” is usually easy to ter stick deflection. Please refer to your aircraft’s instruction manual detect by either a “buzzing” or “humming” sound which comes from for suggested travel limits. the stalled servo. It is possible to increase/decrease the amount that your control surface The following diagram is designed to help clarify how to increase or moves at full stick deflection by mechanical adjustments. decrease control surface travel mechanically to eliminate control sur- face “binding” and servo “stalling”. It is imperative that the servo does not attempt to push/pull the con- trol surface past its mechanical limits. This condition is called “binding.” When a servo moves a control surface into a “binding” position, the servo itself then becomes “stalled,” unable to reach its full deflection. This condition is both harmful to your control linkage and to your servo. This “stalled” condition will also force the servo to drain power Figure 1 Normal (Linear) Figure 2 Increased Control Figure 3 Reduced Control Linkage Set Up Surface Movement Surface Movement Control Rod Control Rod Control Rod Servo Arm Control Surface Arm Servo Arm Control Surface Arm Servo Arm Control Surface Arm (Horn) (Horn) (Horn) To increase control surface travel, select a linkage attachment point fur- also use any combination of these positions to achieve proper control ther outward on the servo arm or further inward on the control horn surface/servo travel. closer to the control surface (Figure 2).

Quite simply, by moving the control rod in on the servo arm/wheel, control surface travel will be reduced, and by moving the control rod out on the servo arm, the control surface travel will be increased.

NOTE: The slave radio must be left off. 4. Test all the control functions on your aircraft with the master radio. 5. Push the trainer button on the master transmitter and check all the control functions with the slave radio. 10.3 RANGE TESTING YOUR MODEL We suggest that before the initial flight of your model, you first NOTE: If your test falls short of the described range, confirm that your perform a ground range test to ensure that the transmitting/receiving NiCad batteries are fully charged. If this situation remains abilities of your EXPERT perform properly. Conduct the range test unchanged, please contact the Horizon Service Center (address as follows: and phone number at the back of this manual) before attempt- ing to fly your model. Do not extend the transmitter antenna at this time. Turn your EXPERT transmitter “on.” Next, turn the model switch “on.” Slowly walk away from the model while moving the control surfaces. The system should function properly to a distance of approximately 60-65 feet. 14 EXPERT Manual
