•ELEVATOR/FLAP MIXING
ELEVATOR -> FLAP MIXING
• Switch 10 : ACT
• Switch 18 : T R I M
• 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 t o T R I M .
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 (PRE-SET FLAPS AND ELEV. TRIM)
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
Fig. 61
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 1 9 . 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.
