Radio Controls:
The transmitter controls setup are totally dependant upon the radio system you are using and the MODE
you are flying. In the USA, the MODE is generally “mode - 2”. Mode two (2) and will assumed. A briefly
description of the transmitter control functions and how they relate to the airplane control surfaces follows. For
a complete discussion of the transmitter control functions, please consult, read, and thoroughly understand the
manufacturer’s manual that came with your transmitter.
The two transmitter control “sticks” (left and right sticks; hereafter referred to as “LS” and “RS”)
control the flight surface functions as follows:
Left Stick (LS): Controls the Rudder (left-right) and Throttle (up-down)
Right Stick (RS): Controls the Ailerons (left-right) and elevator (up-down)
(*) The “Transmitter - Stick” movements (below) are assuming that only one stick is moved and in one
direction only at a time. The aircraft response to movement to one or more sticks simultaneously is beyond the
intended scope of this assembly manual
. Consult your transmitter manual or a flight instruction book.
Roll Control (Ailerons):
Stick Position
Control Surface Response
Plane Response *
RS to Right
Right aileron up
Plane rolls to right (1)
Left aileron down
RS to Left
Left aileron up
Plane rolls to left (1)
Right aileron down
Pitch (Up - Down) Control (Elevator):
Stick Position
Control Surface Response
Plane Response *
RS to lower (down)
Elevator moves upward
Plane Climbs
RS to top (up)
Elevator moves downward
Plane Descends (Dives)
Yaw Control (left-right) (Rudder):
Stick Position
Control Surface Response
Plane Response *
LS to Right
Rudder moves to right
Plane “Flat” turns to right (1)
LS to Left
Rudder moves to left
Plane “Flat” turns to left (1)
Throttle Control (Engine Speed):
Stick Position
Control Surface Response
Plane Response *
LS to top (up)
Engine speeds up
Plane accelerates
LS to Bottom (down)
Engine goes to idle
Plane slows down, descends
(1) Most all control surfaces have some control cross-coupling. The rudder will cause some induced
rolling function and the ailerons will induce some yaw function.
