AIRPLANE – ACRO MODE
INTRODUCTION
The ACRO mode of the XP9303 system is intended for 
powered fixed-wing aircraft. It contains a host of advanced 
features that are easy to set up and use, and are designed 
to assist the pilot in realizing the full potential of the 
aircraft. These features include but are not limited to:
• Switch Assignments
• Flight Modes (3)
• Dual Rates/Exponential (2 or 3 sets for Aileron, 
Elevator and Rudder)
• Wing Type (Normal, Flaperon, Delta)
• Aileron Differential
• V-Tail
• Dual Channels for All Primary Flight Controls 
and Flaps
• Dual Throttles (With Independent Trims and 
Throttle Curves)
• Adjustable Trim Rates (10–100 Trim Steps)
• Built-In Elevator-To-Flap Mixing
• Built-In Aileron-To-Rudder Mixing
• Throttle Curves (2)
• Flap System (With Elevator Trim, Auto Land, 
Elevator/Flap Delay)
• Snap Roll System (4 Directions/Rates Assigned to 
Flight Modes)
• Gyro System (In-Flight Gain Selection of 3 Gains 
for up to 2 Gyros)
• Servo Speed (Independent in Both Directions 
– Eliminates Door Sequencers)
• 6 Programmable Mixers (Includes 2 Multi-Point 
Mixers)
• Fail Safe (Hold or Predetermined Positions)
• Trainer System (Selectable Channels for Student 
Control)
• Timers (Stopwatch, Countdown, Integrated)
• Servo Monitor (Automatically Renames Channels 
According to Assignments)
In addition to the numerous features listed above, the 
XP9303 provides the ability to combine these features 
during flight, using a single Flight Mode switch. This 
capability dramatically reduces the pilot’s work load, 
allowing the pilot to concentrate on flying the aircraft 
instead of worrying about how to operate the transmitter 
(TX).
ACRO PROGRAMMING - PLEASE 
READ
For those who are comfortable with programming and 
would like to dive right in with a minimum amount of 
explanation, there are a few ACRO programming 
examples at the end of this manual. Those who are not 
so inclined are encouraged to continue reading this part 
of the manual in order to acquire an understanding of 
the basic XP9303 programming philosophy, functions, 
and techniques. 
The XP9303 menus and functions are presented 
here in the order that they should be addressed 
when setting up a new aircraft. It begins with 
entering the SYSTEM Menu, selecting a model and 
activating the ACRO mode and progresses through the 
remainder of the SYSTEM Menu options and then 
through the individual functions. The descriptions are 
general in nature and provide enough information to 
identify the purpose of a function, to decide whether or 
not to use a function, and what types of selections and 
settings to make.
Those who have some experience with computer-based 
radios will probably be able to program their aircraft 
as they read through this section, owing to the fact that 
the individual functions are generally simple in nature 
and the XP9303 is a very intuitive system. In 
those instances where more detailed information is 
desired/required for a particular function, detailed 
descriptions of the ACRO functions are included at 
the end of the ACRO section.
ACRO - GETTING STARTED – SYSTEM 
MENU BASICS
Getting started always begins with accessing the SYSTEM 
Menu. This is where models are selected, the mode is 
identified, modulation type is indicated, and where other 
high-level information is collected about the model. 
It is also used to activate some of the more advanced 
programming features such as Flight Modes, Switch 
Assignments, Wing Type and Dual Control information.
