[. . . ] This results in superior neutral characteristics. Such characteristics make it ideal for use with the rudder channel of a model helicopter or in the aileron/ elevator channel of a model aircraft. ·Large 2mm diameter gyro motor shaft for long life and strength. [. . . ] *When the transmitter landing gear switch is pulled forward (or down), the output sensitivity can be adjusted from 0 to 100% with trimmer (1). *When the transmitter landing gear switch is pushed back (or up), the output sensitivity can be adjusted from 0 to 100% with trimmer (2). In this case, trimmers (1) and (2) do not interfere with each other, and can be adjusted independently. ·When the output is fixed or there is no spare channel (as with 4 channel set), do not connect connector (B). In this case, adjust the output with control box trimmers (1) and (2). (Insulate the terminals with vinyl tape so they cannot be touched. ) EXAMPLE Adjustment when installed in a helicopter: When using the switchable output sensitivity: Set trimmer (1) to about the 80% of maximum output sensitivity position (100% is full clockwise) as a starting point. Hover with the wind and readjust trimmer (1) so that "tail hunting" does not occur. However, do not reduce output sensitivity to a point where the nose will turn upwind when "lifting off". Set trimmer (2) to about the 60% position when a large rudder travel is unnecessary, such as 540° stall turns, etc. Approx. 80% Control box *When trimmer (1) is 0, the output can be adjusted from 0 to 50% with trimmer (2). *When trimmer (1) is 100%, the output can be adjusted from 50 to 100% with trimmer (2). POWER SUPPLY ·When using the rate gyro with a separate power supply (utilizing the motor voltage regulator), connect the five cell Nicad battery pack (6V) to connector (C). Thereby, maintaining constant motor speed and consistent gyro performance. A four cell Nicad (4. 8V) battery pack cannot be connected to connector (C). ·Whenever a four cell Nicad battery pack (4. 8V) is used, it must be as a common power supply for the receiver and gyro. Connect the accessory jumper connector to connector (C), when using a 4. 8 volt power supply. ·When the receiver and gyro use a common power supply, rudder/servo power consumption and the power consumed by the gyro, increases the total power consumption. This decreases the number of permissible flights. The use of a high capacity (4. 8/1, 000mA) Nicad battery is recommended. [. . . ] ·Attach the gyro to the fuselage with double-side adhesive tape. INSTALLING THE CONTROL BOX Using the control box nameplate as a template, drill four holes and cut an opening for the slide power switch. Mount the control box on the fuselage, away from engine exhaust and where there is minimal vibration. -Pan head tapping screw(2) 2x8 Use double-sided adhesive tape (Clean the mounting surface and stick the gyro to it with double-side adhesive tape. ) Switch box nameplate Switch box (top) Switch box (bottom) Use double-side adhesive tape about 3mm thick and 10mm wide. ·Wrap the control amplifier in sponge, to prevent vibration problems.
