Instruction manual for Futaba digital proportional radio control set FM D60400. Describes the features and characteristics of the FP-5NLH helicopter FM proportional radio control set.
This manual describes the Futaba FP-5NLH digital proportional radio control set designed specifically for helicopters. The set includes the FP-TS5NLH transmitter, FP-R107N receiver, and FP-S130 servos. Key features include servo reversing switches for all channels, adjustable servo throw (AST) for aileron and elevator, and a pitch control trimmer.
| Operating system | 2 stick, 5 channels w/servo reverse, aileron and elevator AST, helicopter mechanism |
|---|---|
| Transmitting frequency | 72MHz band, 53MHz band |
| Modulation system | FM (Frequency modulation) |
| Power requirement (Transmitter) | 9.6 volts NiCad battery (NT-8LP) |
| Current drain (Transmitter) | 170mA (at 12V) |
| Receiving range (Ground) | 550 yards (500m) |
| Receiving range (Air) | 1,100 yard (1000m) |
| Output torque (Servo) | 55.6 oz.in (4kg-cm) |
| Operating speed (Servo) | 0.24sec/60° |
When ON, the throttle servo stops at the position set with the trimmer, allowing only the pitch servo to be controlled by the throttle stick for auto rotation landings.
When pulled forward, it turns on the idle up function, making the position set with the idle up trimmer the maximum slow position of the throttle servo.
Approximately 30% of the full throw of the servo can be adjusted and set using the pitch control trimming knob.
They are used for cancelling the torque reaction of the main rotor by adjusting the minimum mixing necessary for helicopter flight.
