Basic flying features are quite simple and almost perfect as a starter for pilots. Takeoff and landing is simple and due to its slow flying speed, the Dragonfly is perfect for scenery exploration.

=== Instrumentation ===
=== Configuration ===
The airspeed indicator gauge can be configured to display either km/h, mph or kts by setting the property '''/instrumentation/airspeed-indicator/texture''' to either
Being an ultralight aircraft with less regulation than seen on typical aircraft, the Dragonfly can be equipped with a variety of different instrumentations. To set it up in a way you like, go to the menu, Moyes Dragonfly -> Configuration. There you can set various options:
* Airspeed-kmh.rgb
==== Big Panel ====
* Airspeed-mph.rgb
This enables an instrument panel to the left of the pilot, including a standard size airspeed indicator, altimeter, RPM and coolant temperature indicator as well as a compass.
* Airspeed-kts.rgb
==== EIS-2000G ====
This can be done on startup as a command line switch or at runtime by setting the property with the [[Property browser]].
This simulates a compact engine monitor, namely the EIS-2000G (Engine Information System) as described [http://grtavionics.com/home/eis-engine-monitors/ here]. Although it is not yet complete, the functionality available works as described in the [[Moyes_Dragonfly#External_links|flight manual]].
 
==== Hall Wind Meter ====
Example: Use airspeed indicator calibrated in KTS:
The hall wind meter is a simplistic airspeed indicator, basically working by having a "floating" plate inside a transparent tube. See [https://hallwindmeter.com/ the manufacturer's website] for more information.
fgfs --aircraft=Dragonfly --prop:/instrumentation/airspeed-indicator/texture=Airspeed-kts.rgb
==== Units ====
For the airspeed indicator and the hall wind meter, the indicated unit can be selected. <br />
Available options are:
# for the '''airspeed indicator''':
#* '''kph''' (kilometers per hour)
#* '''mph''' (statute miles per hour)
#* '''kts''' (knots/nautical miles per hour)
# for the '''hall wind meter''':
#* '''kph''' (kilometers per hour)
#* '''mph''' (statute miles per hour)
==== Other options ====
You can also select which texture to use for the [[Moyes_Dragonfly#Banner_towing|banner]] and whether/in which manner human models shall be displayed.


=== Banner towing ===
=== Banner towing ===
The FlightGear model of the Dragonfly supports banner towing. The banner to tow has to be picked up from the ground during the flight and can be released in flight before landing.

To use this feature, a small configuration file is needed telling FlightGear where the banners are on the ground. It is a small XML file placed in your FlightGear home directory (which is <tt>~/.fgfs</tt> on Linux and <tt>.../Users/.../AppData/Roaming/flightgear.org/</tt> on Windows) named <tt>groundbanner.xml</tt>. Create this file and paste the following content into it; it will tell FlightGear where to put the banner:
There are two possible ways to create a banner: You can either place one about 50m to your right by using the menu (Moyes Dragonfly -> Place Banner) or you can place it at specific coordinates using a small configuration file:

== Flying the Moyes Dragonfly ==

The aircraft contains checklists to guide you through the preflight checks and starting the engine. Additionally, the EIS-2000G includes a reduced before takeoff checklist that is displayed on start.
=== Starting the engine ===
Starting the Rotax 582 is pretty easy, after assuring that the propeller area is clear, there are only three steps to take:
# Switch on the '''master switch'''
# Switch the '''left and right magnetos''' on
# Press the starter button until the engine catches
It helps to add a bit of throttle for starting the engine.
Note that the engine does not have a mixture lever, as the mixture is automatically regulated using a technique called "High Altitude Compensation" (HAC). Page 6 of this [https://legacy.rotaxowner.com/si_tb_info/serviceinfo/5ul89.pdf Service Information] contains more information about this system.

This is definitely something different, the classic ultralight trike, somethings I have not flown before in the simulator.  Personally I have seen these things droning overhead and flown very freely, but I have wondered what it would be like to fly.

== Issues ==
* aerodynamic coefficients are a very rough guess
* aerodynamics and movement of the banner is far from being realistic
* banners do not disappear from ground after pickup
* add a pilot when viewing from outside
