•ELEVATOR/FLAP MIXING

ELEVATOR -> FLAP MIXING

• Switch 10 : ACT

• Switch 18 : TRIM

• Elevator -> Flap (2 -> 6) mixing is unidirectional

with elevator (CH2) acting as the Master chan-

nel. This function can be helpful in looping,

square cornered, and circular acrobatic maneu-

vers. Set up the function as follows:

Set Safety Switch 10 to ACT and Flap Switch

18 toTRIM.

Set Control Switch 12 to ON and adjust Trim-

mer [9] to give DOWN flaps with UP elevator

stick movement.

Fig. 58

Initially, set deflection angles so that the flap

down angle is approximately the same

as

the

elevator up angle.

Transmitter Control Switch 12 is used to turn

this function ON and OFF in flight as desired.

FLIGHT ADJUSTMENT

Make a test flight with Switch 12 OFF and

adjust the Elevator trim and deflection to suit.

Turn Switch 12 ON and test control response.

If the response is not correct, turn switch 12

OFF, land and adjust flap deflection with Trim-

mer

9

.

Most common maneuvers can be performed

with the mixing function ON. Rolls and spins

may be better without the mixing depending on

the aircraft. Mixing is generally not recom-

mended for landing.

FLAP -> ELEVATOR MIXING (ELEVATOR DOWN MIXING) ADJUSTMENT

•This

is

a

pre-set

or

switch-activated

type

of mix-

ing and is ideal for landing approaches with

stunt and scale aircraft. An airbrake effect is

produced which is very realistic and makes short

field landings easier.

Flaps 45 ~60

Set Airbrake Switch 32 (6, 7 -> 2 MIX) to ON.

Monitor Lamp (C) comes ON. Control Switch

10 can be used to turn the function ON and

OFF

in flight. When Switch 10 is ON, Lamp

C Blinks.

Turn Switch 10 ON and set Flap Knob 6 to

Zero. Lower the flaps 45 to 60 degrees using

Trimmer 20 and set the Elevators about 3

degrees down using Trimmer 19. NOTE: These

settings are estimates and will vary depending

on elevator and flap areas, etc.

Set Switch 10 to OFF for takeoff. When at a

safe altitude, reduce the throttle to medium

slow and after the aircraft has slowed some-

what, turn Switch 10 to ON. The aircraft

should maintain level flight. If the aircraft

climbs or dives, set Switch 10 to OFF, land,

and readjust the elevator angle as necessary

with Trimmer 19 . Remember, do NOT try to

adjust back panel trimmers while in Flight.

Make adjustments in small steps.

Flap Neutral position can be changed in flight

using the Flap Knob 6 . This applies whether

mixing in ON or OFF.
