•FEATURES The FP-8SSAP was specially developed to use PCM (pulse code modulation) for FAI RC aerobatics F3A aircraft. It is an extremely noise and dead-point resistant digital proportional RC set with a microprocessor in the transmitter and the receiver. Please read this manual before using your set.

ADJUSTMENTS AND FLIGHT TECHNIQUES •BASIC LINKAGES AND INSTALLATION The FP-8SSAP has a servo reversing switch and ATV (Adjustable Travel Volume) for each channel. Mount the servos without regard to their direction. Select and link servo horns somewhat larger than those specified by the model manufacturer.

Other aircraft may require slightly allows independent adjustment of servo maximum different RIGHT or LEFT aileron or rudder throw in each direction (without affecting the deflection to give equal response in each direction neutral position).

ADJUSTMENTS AND FLIGHT TECHNIQUES •USING DUAL RATE (AILERON, ELEVATOR, AND RUDDER) Dual rate functions allow the flyer to alter the tings). At D/R ON, servo deflection is reduced by maximum servo travel (and therefore control sensi- a percentage set with the D/R trimmers. Dual rate tivity) during flight by using the appropriate rate adjustments always effect both directions of servo switch.
ADJUSTMENTS AND FLIGHT TECHNIQUES •AUTOMATIC DUAL RATE ON RUDDER • This function automatically switches rudder D/R to ON as the throttle lever is moved from LOW to HIGH position. This allows a smaller rudder throw for precise inputs during rolling maneuvers (at HIGH throt- tle) and increased throw (at LOW throttle) during stall turns, taxing, etc.
ADJUSTMENTS AND FLIGHT TECHNIQUES •SUGGESTIONS ON ATV, D/R, AND VTR POINTS TO REMEMBER (ATV, D/R. VTR) • Servo maximum deflection is always determined by ATV. If no ATV is set, maximum travel is governed by the servo itself and is approximately 45 degrees in each direction from neutral.
ADJUSTMENTS AND FLIGHT TECHNIQUES •USING ATL (ADJUSTABLE THROTTLE LIMIT) The Throttle Trim Lever 19 affects the servo po- sition only when the throttle control lever is in the LOW (IDLE) position. HIGH throttle position HIGH SLOW remains unchanged. Adjustment of the throttle linkage is therefore very convenient.

ADJUSTMENTS AND FLIGHT TECHNIQUES •AIRCRAFT WITH VARIABLE PITCH PROP ADVANTAGES OF VARIABLE PITCH PROPELLEJB The variable pitch propeller offers such advantages as: 1. The desired speed and pull can be adjusted. 2. Speed matched to the engine is obtained. 3. Low noise. 4.
ADJUSTMENTS AND FLIGHT TECHNIQUES Pitch zero does not have an air braking affect. If the engine is running at a speed of 3000 ~ 4000 Pitch 11 Pitch 8-9 (maximum) rpm, the air braking effect will not appear if the propeller diameter is too small.
ADJUSTMENTS AND FLIGHT TECHNIQUES •AIRCRAFT WITH FLAPS Connect the flap servo to channel 6 of the receiver. • Wide throw is often best for normal landing flaps and airbrake operations. • Flaps are normally controlled by the CH6 Knob Narrow (Trim) throw allows Flaps or Flprons on the transmitter front.

ADJUSTMENTS AND FLIGHT TECHNIQUES EXAMPLE 1. Pig. 58. AILERON -> RUDDER MIXING • This function is sometimes referred to as"CAR" (Coupled Ailerons and Rudder) and is useful on sailplanes and certain scale models where aileron and rudder must be used together for coordinated turns. 1.Connector 14 designates the Master channel and is set vertically at the CH1 (Aileron) posi- tion.
ADJUSTMENTS AND FLIGHT TECHNIQUES •MUTUAL (BI-DIRECTIONAL) MIXING (FLPRON. ELEVN, V-TAIL, DIFF) Aileron + flap (FLPRON), aileron + elevator (ELEVN), rudder + elevator (V.TAIL), and aileron differential (DIF) mixing can be selected with a switch.

ADJUSTMENTS AND FLIGHT TECHNIQUES ELEVN (AILERON + ELEVATOR) • This type of mixing can be used with tailless and delta wing aircraft and flying discs. • Install and connect the servos as shown in Fig. 64. Always connect the Right side servo to CH1 (Aileron).
