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.
