INTRODUCTION
The Heli mode of the X9503 2.4 system is intended for 
use in model helicopters with all types of Swashplate 
mixing. It contains a host of advanced features that are 
easy to set up and use. The features have been designed 
to assist the pilot in realizing the full potential of the 
helicopter. These features include:
• Switch Assignments for Specific Channels/
Functions
• Flight Modes (up to 6)
• Dual Rates/Exponential (up to 3 settings each for 
Aileron, Elevator and Rudder)
• Swashplate Type (Normal, 120, 140, and 
90 CCPM)
• Adjustable Trim Rates (10 – 100 Trim Steps)
• Built-In Cyclic-to-Throttle Mixing for Aileron, 
Elevator, and Rudder
• Governor Pre-Program Mix
• Throttle Curves (up to 5) with up to 7 Points 
• Pitch Curves (up to 6) with up to 7 Points 
• Gyro System (In Flight Gain Selection of 
up to 3 Gains)
• 6 Programmable Mixes (Includes 2 Multi-Point and 
4 Standard Mixes)
• Fail-Safe (Hold or Predetermined Positions)
•Trainer System (Selectable Channels for 
Student Control)
• Timers (Stopwatch, Count-Down, Integrated)
• Servo Monitor (Automatically Renames Channels 
According to Assignments)
In addition, the X9503 2.4 allows you to combine, 
activate, and deactivate multiple features such as Dual 
Rates, Gyro Gain, and Governor settings, using the Flight 
Mode switch. This capability dramatically reduces your 
workload, allowing you to focus on the task of flying.
Even if you’re comfortable with programming, you 
should still read this part of the manual to get a basic 
understanding of the X9503 2.4. 
This section begins with entering the System Menu, 
selecting a model and activating the HELI Mode, and 
progresses through the remainder of the System Menu 
options and then through the individual functions. The 
descriptions here are general in nature and serve to 
identify the available functions, why they are included and 
when a particular function should be used. 
Those who have some experience with computer radios 
will probably be able to program their helicopter as they 
read through this section, as individual functions are 
generally simple and the X9503 2.4 is very intuitive. 
Getting started begins with accessing the SYSTEM Menu. 
This is where you select models, identify modes, indicate 
modulation type and store other high-level information 
for the model.  You can also activate some of the more 
advanced programming features such as Swashplate Types 
and Governor Program activation.
