// Example and reference Arducopter 2.0 configuration file
// =======================================================
//
// This file contains documentation and examples for configuration options
// supported by the ArduPilot Mega software.
//
// Most of these options are just that - optional. You should create
// the APM_Config.h file and use this file as a reference for options
// that you want to change. Don't copy this file directly; the options
// described here and their default values may change over time.
//
// Each item is marked with a keyword describing when you should set it:
//
// REQUIRED
// You must configure this in your APM_Config.h file. The
// software will not compile if the option is not set.
//
// OPTIONAL
// The option has a sensible default (which will be described
// here), but you may wish to override it.
//
// EXPERIMENTAL
// You should configure this option unless you are prepared
// to deal with potential problems. It may relate to a feature
// still in development, or which is not yet adequately tested.
//
// DEBUG
// The option should only be set if you are debugging the
// software, or if you are gathering information for a bug
// report.
//
// NOTE:
// Many of these settings are considered 'factory defaults', and the
// live value is stored and managed in the ArduPilot Mega EEPROM.
// Use the setup 'factoryreset' command after changing options in
// your APM_Config.h file.
//
// Units
// -----
//
// Unless indicated otherwise, numeric quantities use the following units:
//
// Measurement | Unit
// ------------+-------------------------------------
// angle | degrees
// distance | metres
// speed | metres per second
// servo angle | microseconds
// voltage | volts
// times | seconds
// throttle | percent

//
// ATTENTION: Some APM boards have radio channels marked 0-7, and
// others have them marked the standard 1-8. The FLIGHT_MODE_CHANNEL option
// uses channel numbers 1-8 (and defaults to 8).
//
// If you only have a three-position switch or just want three modes, set your
// switch to produce 1165, 1425, and 1815 microseconds and configure
// FLIGHT_MODE 1 & 2, 3 & 4 and 5 & 6 to be the same. This is the default.
//
//
// For more modes (up to six), set your switch(es) to produce any of 1165,

// |
// FLY_BY_WIRE_B | Autopilot style control via user input, aispeed controlled with throttle.
// |
// RTL | Returns to the Home location and then LOITERs at a safe altitude.
// |
// AUTO | Autonomous flight based on programmed waypoints. Use the WaypointWriter
// | application or your Ground Control System to edit and upload
// | waypoints and other commands.
// |
//
//
// The following non-standard modes are EXPERIMENTAL:

// THROTTLE_FAILSAFE OPTIONAL
// THROTTLE_FS_VALUE OPTIONAL
// THROTTLE_FAILSAFE_ACTION OPTIONAL
//
// The throttle failsafe allows you to configure a software failsafe activated
// by a setting on the throttle input channel (channel 3).
//
// This can be used to achieve a failsafe override on loss of radio control
// without having to sacrifice one of your FLIGHT_MODE settings, as the
// throttle failsafe overrides the switch-selected mode.
//
// Throttle failsafe is enabled by setting THROTTLE_FAILSAFE to 1. The default
// is for it to be disabled.
//
// If the throttle failsafe is enabled, THROTTLE_FS_VALUE sets the channel value
// below which the failsafe engages. The default is 975ms, which is a very low
// throttle setting. Most transmitters will let you trim the manual throttle
// position up so that you cannot engage the failsafe with a regular stick movement.
//
// Configure your receiver's failsafe setting for the throttle channel to the
// absolute minimum, and use setup pwm program in the CLI to check that
// you cannot reach that value with the throttle control. Leave a margin of
// at least 50 microseconds between the lowest throttle setting and
// THROTTLE_FS_VALUE.
//
// The FAILSAFE_ACTION setting determines what AC2 will do when throttle failsafe
// mode is entered while flying in AUTO mode. This is important in order to avoid
// accidental failsafe behaviour when flying waypoints that take the aircraft
// temporarily out of radio range.
//
// If FAILSAFE_ACTION is 1, when failsafe is entered in AUTO modes,
// the aircraft will head for home in RTL mode. If the throttle channel moves
// back up, it will return to AUTO mode.
//
// The default behaviour is to ignore throttle failsafe in AUTO and LOITER modes.
