User manual FUTABA ATTACK_III

[. . . ] · Despite being a microservo, operating speed is a fast 0. 21 sec/ 60° and output torque is a high 2. 2 kg/cm. RECEIVER FP-R114H · High performance AM 4 channel receiver in which miniature size and light weight have been achieved by using the PC board space to the maximum. · Narrow band ceramic filter improves rejection of adjacent channel interference. SET CONTENTS AND RATINGS (Specifications are subject to change without prior notice. ) FP-4NBL RECEIVER WITH LINEAR CONTROLLER MCR-4A · FET amplifier with miniature lightweight AM 4-channel receiver and motor controller in one pack. · Since the drive motor power supply (7. 2 V NiCd battery pack, etc. ) can also be used to power the receiver and servos, troublesome wiring is unnecessary and the model can be made lighter. · Built-in high performance low voltage "autocut" circuit prevents loss of control due to power supply voltage drop during flight.

Fig. Transmitter crystal Battery cover Charging of transmitter and receiver Nicad batteries Recharge the receiver and transmitter Nicad batteries as shown in Fig. · If the drive motor is stopped by the "autocut" function during flight, land the aircraft immediately and safely. The idle point trimmer sets the drive motor idling point. · Set the transmitter throttle servo reversing switch to the normal position. · Set the transmit throttle stick to the slowest position (stick all the way back ), turn on the MCR-4A power switch, press the start switch, and set the idle point trimmer to the point at which the motor idles. · If the start switch is not pressed, the drive motor will not run. · Turn the idle point trimmer slowly and without too much force. PRECAUTIONS · Connect the receiver (or MCR-4A), servos, switches, and battery firmly as shown in Fig. Operate the transmitter sticks and check that each servo follows the movement of the stick. · Connect the pushrod to each servo horn, then check if the direction of travel of each servo matches the direction of operation of its transmitter stick. To reverse the direction of servo travel, switch the servo reversing switch. · Operate each servo over its full travel, 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 battery. Always make the travel of each control mechanism somewhat larger than the full travel (including trim) of the servo horn. [. . . ] · When installing the switch harness, cut a rectangular hole somewhat larger than the full stroke of the switch and install the switch so that it moves smoothly from ON to OFF. This also applies to the switch mount when the switch is installed inside the fuselage and is turned on and off from the outside with a piece of wire, etc. Install the switch where it will not be exposed to engine oil, dust, etc. · Even though the receiver antenna is long, do not cut or bundle it.
