The Two Common Types of Power: Electric and Glow
Model Setup Menu Programming for Helicopter
This section describes how to use the Optic 6 Sport 2.4’s helicopter functions (model type HELI).
Descriptions of the other functions, such as endpoints, dual rates, expo, etc., are contained in the aircraft (ACRO) section
There are some subtle, but important differences in the setup methods for glow- versus electric-powered heli's:
If your Heli is powered by a glow engine:
1. A servo plugged into the Ch. 3 slot of the receiver controls the carburetor throttle plate of the engine.
2. Glow heli's also have their own "on-board" battery to power the receiver, gyro and servos.
If your Heli is powered by an electric motor:
1. A proportional ESC (Electronic Speed Control) is plugged into the Ch. 3 receiver slot to control the RPM of the motor.
The Speed Control may have settings that need to be programmed so check the Speed Controller manual.
2. In smaller electric heli's a large motor battery provides the power for the servos, gyro and receiver through a BEC (battery eliminator circuit)
of the ESC (electronic speed control). Larger electric heli's will carry a separate receiver battery to power the servos, receiver and gyro.

Model Setup Menu Programming
To set up the Optic 6 Sport 2.4 to fly a particular model, you need to get into the radio's model setup menu. In this menu you can program specific
control functions and the value (the amount of servo travel) for the particular model helicopter you selected earlier in the initial setup menu.
Go ahead and switch the transmitter on-you are now in the standard operating screen
In the upper left-hand corner it will say "HELI" and to the right there will be a large number telling you the state of the battery voltage
(such as 7.2 v) and a smaller single-digit number indicating the model slot the radio is currently opened to.
There will also be a little black box at the bottom of the screen with the symbol "NOR".
This indicates that the system is currently in the "normal" flight condition mode which in HELI is also known as the NORMAL curve.
Later, we will show you how to activate the flight condition modes, or "Idle-Up" stunt modes-and it is here on the screen where you will be
told which mode is currently active.
Note: If you have previously set up a model in ACRO, you will notice that in the HELI programming
baseline five new functions appear that weren't in the ACRO mode.
Throttle Curve, Pitch Curve, Gyro Gain, Revolution Mix and Throttle Hold. All will be explained in
the descriptions of these features which appear exclusively in the HELI menu.
Now push down both EDIT buttons at the same time.
The following menu items-in the order in which they appear-will come on the transmitter's LCD screen as you scroll down the list by pushing
down the Right EDIT button:
The Two Fundamental Types of Helicopter's: Fixed Pitch and Collective Pitch
There are two fundamental types of model heli's, fixed pitch and collective pitch.
The fixed pitch heli is simpler to operate and has fewer moving parts as the motor or engine RPM
controls the speed of the "fixed" pitch blades of the heli.
For this fixed pitch function you will use the Throttle curve function of the Optic Sport, but not the
Pitch curve function.
The other, more common, collective pitch setup uses a mix within the electronics of the radio
transmitter to combine the throttle RPM with the adjustable "pitch" or angle of the heli's blades.
Both Throttle curve and Pitch curve functions of the Optic Sport are used to fine-tune the performance
of a collective pitch heli.
