HOVERING OFFSET ....32 WARNING: The FUTABA PCM1024H system has numerous operating features and is designed for serious and experienced radio con- trol hobbyists. Newcomers to the hobby should seek advice and assistance in operating this set. Improper operation can result in property damage and/or serious personal injury.
•FEATURES The PCM1024H was specially-developed to meet the needs of the serious and demanding R/C Helicopter hobbyist. Numerous features make this system adaptable to a wide variety of complex radio control helicopters and stunt and scale aircraft. This is the most advanced system available for FAI R/C Helicopter (F3C) competition.

ADJUSTABLE FUNCTION RATE AFR is a servo endpoint limiting function, similar to A TV with one exception: AFR limits only the Dual Rate OFF (High-Rate) servo travel. Trim throw/and Dual Rate ON (Low Rate) limits are unaffected (unless AFR is reduced below the D/R ON limit). Setting Method 1) The setting method for AFR is the same as for ATV (See page 16).
ADJUSTMENTS AND FLIGHT TECHNIQUES DUAL RATE Dual Rate functions allow the modeler to switch servo travel limits in flight, thus varying the control sensitivity for different flight conditions or maneuvers. • Dual Rate functions are available on CH1 (Aileron), CH2 (Elevator), and CH4 (Rudder/Tail Rotor). •...

ADJUSTMENTS AND FLIGHT TECHNIQUES MIXING • Mixing allows two or more channels to be controlled by a single transmitter control stick or lever. This set features Programmable Mixing with four independent mixing circuits, along with special built-in mixing circuits. • NOTE: Only PROG-MIX Programable Mixing can be used in the BASIC Parameter mode. (See PARA- METER, page 46).
PROGRAMABLE MIX Programmable Mixing Four separate Programmable Mixing circuits allow almost infinite mixing combinations. The features of this program provide the modeler with unlimited versatility in trimming and controlling complex, high-performance models. • Mixing of any two channels is possible. •...
