Gyro body Connect to receiver retract or auxiliary channel (for gyro sensitivity switching) for Receiver Control amp Control box Gyro output trimmer Jumper connector for Rudder Servo Five battery pack 6V connector Motor regulated power supply. (Insert the jumper connectors when the power supply is shared with the receiver.) •Connect the servos and switches firmly as shown in Fig. 20. Then extend the transmitter and receiver antennas fully. •Set the transmitter power switch to ON. then set the receiver power switch to ON. The servos stop near the neutral position. Operate the transmitter sticks and check if the correspond- ing servos faithfully follow operation of the sticks. •After setting the pushrods at the servo horns, check that the direction of operation of the transmitter sticks and the direction of opera- tion of the rudders are the same. •Operate each servo horn over its entire operat- ing range and check if the pushrod binds, or is too loose. 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 operate smoothly even when the trim lever and stick lever are operated simultaneouly in the same direction. •Be alert for noise. 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 the full stroke of the switch and install the switch so it moves smo- othly from ON to OFF. When the switch is mounted inside the fuselage and is turned ON- OFF with wire, install the switch mount as described above. Install the switch where it will not come into direct contact with engine oil, dust, etc. •Even though the receiver antenna is long. do not cut or bundle it. •The servos, Ni-Cad battery,switches,extension cords, and crystals of FP-7FGH are the same as those of the high-quality J Series. The crystals are extremely precise and are identified by color (red and green). Use Tx and Rx crystals of the same color. •A spare horn is supplied. Use it as needed. •Wrap the receiver in sponge rubber. Place the receiver in a plastic bag and wrap a rubber band around the open end of the bag to waterproof and dustproof the receiver. Do the same with the receiver/servo battery. •Use the rubber bands wrapped around the receiver to hold the servo and switch leads. •After mounting is complete, recheck each part, then make the transmitter antenna as short as possible, extend the receiver antenna fully, and operate the set from a distance of 20m to 30m. The movement of each rudder (servo) should faithfully follow the operation of each stick of the transmitter. 11

servo neutral position at the servo horn. Setting and shifting the neutral position a) Angle divisions 1) The splined horn has 25 seg- ments. The amount of change per segment is; 2) The minimum adjustable angle is determined by the number of arms or number of the holes. For four arms,the minimum adjustable angle is: Baseline A b) Effect Fig. 23 To shift the holes center line to the right (clockwise) relative to baseline A, shift arm 2 to the po- sition of arm 1 and set it to the position closest to baseline A. [Example] For a four arm horn, the angular shift per segment is 14.4°. The shift to the right is 90° - (14.4 x6) =3.6° To shift by the same angle in the opposite direction, use the oppo- site arm number. Fig. 24 For a six arm horn, turn the arm counterclockwise and set arm 2 to the position of arm 1. The ad- justable angle is 60° - (14.4 x 4) =2.4°. Arm 3 shift 4.8° to the right, arm 6 shifts 2.4° to the left,and arm 4 shifts 7.2° to the right and left.

Each frequency band has its own designated color, as stated above. The frequency flag is intended for identification purposes. •Also change the frequency flag when frequency is changed. •Futaba paired crystals are precisely matched. Always use a Futaba crystal set (transmitter, receiver) when changing the frequency. •It is illegal to change crystals of transmitter on the 72-75MHz bands in the U.S.A. 26-27MHz - 26 995 27.045 27.095 27.145 27.195 27.255 72/75MHx • Aircraft only 'Shared 72.030 72.080 72.160 72.240 72.320* 72.400 72550 72.590 72 .630 72.670 72.710 72.750 72.790 72330 72.870 72.910 72.960* 75.640 Aircraft/ 12 —- —-- 38 40 42 44 46 48 50 52 54 56 — - Car/Boat Brown Red Orange Yellow Green Blue Brown-Red (Top Flag/Ribbon- Bottom Flag/Ribbon) White/Brown White/Blue White/Red White/Purple White/Orange Orange-Grey Yellow-Black Yellow-Red Yellow-Yellow Yellow-Blue Yellow-Grey Green-Black Green-Red Green-Yellow Green-Blue White/Yellow White/Green 75MHz- 75.430 75.470 75510 75.550 75.590 75.670 75.710 75.750 75.790 75 .830 75.870 53MHz License 53.100 53.200 53.300 53.400 53500 53.600 53.700 53.8OO Car& Boat 62 64 66 68 70 74 76 78 80 82 84 Aircraft/Ca Required — — - - — — only Blue-Red (Top Flag/Ribb Bottom Flag/R Blue-Yellow Blue-Blue Blue-Grey Purple-Black Purple-Yellow Purple-Blue Purple-Grey Grey-Black Grey-Red Grey-Yellow r/Boat - FCC Amatuer Black/Brown Black/Red Black/Orange Black/Yellow Black/Green Black/Blue Black/Purple Black/Grey aon- ibbon) Not generally in use Frequency Channel No. Flag Color
