ADJUSTMENTS AND FLIGHT TECHNIQUES

•AIRCRAFT WITH FLAPS

Connect the flap servo to channel 6 of the receiver.

• Flaps are normally controlled by the CH6 Knob

6 on the transmitter front. Wide or narrow

(Flap Trim) travel may be selected by Flap

Switch [18] on the trimmer panel.

• Wide throw is often best for normal landing flaps

and airbrake operations.

Narrow (Trim) throw allows Flaps or Flprons

(see page 31 ) to be used for pitch trim adjust-

ments in knife edge and vertical maneuvers.
Narrow throw may also may also be best for
Elevator -> Flap (2 -> 6) mixing.

•ELEVATOR/FLAP MIXING

ELEVATOR -> FLAP MIXING

• 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:

• Switch [10]: ACT
•Switch [18] TRIM

1. Set Safety Switch 10 to ACT and Flap

Switch

18 to TRIM.

2. Set Control Switch 12 to ON and adjust Trim-

mer 9 to give DOWN flaps with UP elevator

movement.

Initially, set deflection angles so that the flap

down angle is approximately the same as the
elevator up angle.

3. Transmitter Control Switch 12 is used to

turn

this function ON and OFF in flight as desired.

FLIGHT ADJUSTMENT

1.Make a test flight with Switch 12 OFF and

adjust the Elevator trim and deflection to suit.

Flaps angle

2.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.

3. 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.
