Page 13: Radio Installation Precautions
RADIO INSTALLATION While you are installing the battery, receiver, and servos into your model’s fuselage, please pay attention to the following guidelines: Servo Notes Mounting Use the supplied rubber grommets when you mount each servo. Be sure not to overtighten the screws. If any portion of the servo case directly contacts the fuselage or the servo rails, the rubber grommets will not attenuate vibration, which can cause mechanical wear and servo failure. - Page 14 Additional extension cords of varying lengths are available from your hobby dealer or Futaba. Vibration and Waterproofing The receiver contains precision electronic parts. Be sure to avoid vibration, shock, and temperature extremes.

- Page 32 D/R — Dual Rates If this is your first computer radio, you may have never been introduced to dual rates before. Dual rates are used because most models respond more rapidly to control inputs while they’re flying at higher speeds, and it is possible to be really gentle with the controls and yet still over-control.

Page 35: Flpr
FLPR — Flaperon Mixing The Flaperon mixing function uses two servos to individually control two ailerons, combining the aileron function with the flap function. Both ailerons can be raised and lowered simultaneously for a flap effect. Of course, aileron function, where the two controls move in different directions, is also performed. -
Page 36: Fltr
FLTR — Flap Trim Function The Flap Trim function is used to specify the amount of flap travel produced by moving the flap control (the CH6 knob). If flaperon ( ) function has been activated, FLPR FLTR automatically turned on. Sailplane folks call this effect “camber,” because the model’s airfoil is changed across the span. -

ABRK — Airbrake Function function, when activated, simultaneously moves the flaps and offsets the elevator, ABRK and may be used to make steep descents or limit airspeed in dives. All the controls move to the defined positions by flipping the airbrake switch downwards. Normally, with a single flap, the flap is dropped. -

ELVN — Elevon Mixing The Elevon function should be used with delta wings, flying wings, and other tailless aircraft whose layouts combine the aileron and elevator functions, and requires one servo for each elevon. Connect the right aileron to receiver CH1/AIL and the left aileron to CH2/ELE. The amount of aileron and elevator response can be adjusted Aileron operation independently. -
Page 40: Rudder Coupling
1->4 — Aileron -> Rudder Mixing Aileron-to-rudder mixing is a function which causes the rudder to move automatically with the motion of the aileron stick. This is done because when ailerons are used to command a turn, the down-moving aileron has more drag than the up-moving one, so the plane’s fuselage tries to yaw against the turn. - Page 41 6->2 — Flap -> Elevator Mixing Flap-to-elevator mixing trims the elevator to compensate for trim changes when the flaps are commanded to drop or rise. This usually requires a relatively small amount of elevator travel. The mixing point may also be offset to match the neutral flap position. Inputting settings for 6 ->...
