[. . . ] 5 RECEIVER, SERVO, & SWITCH HARNESS. 6 THROTTLE->RUDDER MIXING ADJUSTMENT. 9 IMPORTANT: _______________________________________________________ AN FCC CLASS C LICENSE IS REQUIRED TO OPERATE THIS SYSTEM. WRITE TO THE FEDERAL COMMUNICATIONS COMMISSION AS LISTED BELOW FOR AN APPLICATION FORM #505. [. . . ] 3 ·OPENING THE TRANSMITTER REAR COVER AND LOADING THE PENLIGHT BATTERIES 4 · Remove the rear cover of the transmitter as shown in Fig. 4 and load the 7 pen-cell batteries in the correct polarity. · Extend the antenna fully and set the POWER switch to ON. The meter pointer should deflect to the green zone. If the meter pointer does not move, or moves very little, check for poor battery contact, incorrect battery polarity, or faulty batteries. · When the meter pointer enters the red zone, the range of the radio waves will become short. Change the batteries when the meter pointer drops to the boundary between the red and green zones. · Use the trim lever to fine adjust each rudder. This lever can also be used to adjust the neutral position and the flight posture after the mechanism has been mounted. However, after test flight, all adjustments should be made with the rod adjusters, etc. and the lever handle should be left in the neutral position as much as possible. Applying unreasonable force to the servo horn will adversely affect the servo and quickly drain the batteries. Always make the operating width of each rudder somewhat larger than the full stroke (including trim) of the servo horn. Adjust the servo horns so that they operate smoothly even when the trim lever and stick lever are operated simultaneously in the same direction. 5 Fig. If engine vibration causes metal parts to touch, noise will be produced and the receiver and servos may operate incorrectly. We recommend the use of noiseless parts. · When installing the switch, cut a rectangular hole somewhat larger than full stroke of the switch and install the switch so that it moves smoothly from ON to OFF. When the switch is mounted inside the fuselage and is turned ON-OFF with wire, install the switch mount in the same manner. Install the switch where it will not come into direct contact with the engine oil, dust, etc. · Even though the receiver antenna is long, do not cut or bundle it. Do not forget to install the tooth washer when changing the horn. ·Wrap the receiver in sponge rubber. [. . . ] (In the L to H direction. ) ·Under this state, turn the MIX trimmer about halfway in the R (right) direction and check the rudder movement (rudder servo) while moving the throttle stick up and down. The rudder should move a little to the right at SLOW and a little to the left at HIGH. ·Set the MIX trimmer to zero (center) at throttle stick HIGH. The rudder servo should not move because the mixing amount is zero at throttle HIGH as shown in Fig. [. . . ]
