# Helicopters

<LinkedBadge type="warning" text="Experimental" url="../airframes/#experimental-vehicles"/>
|
|
|
|
:::warning
|
|
Support for helicopters is [experimental](../airframes/index.md#experimental-vehicles).
|
|
Maintainer volunteers, [contribution](../contribute/index.md) of new features, new frame configurations, or other improvements would all be very welcome!
|
|
|
|
Issues include:
|
|
|
|
- Limited support for different types of helicopters.
|
|
For example, PX4 does not support helicopters with coaxial or dual rotor types, and features such as RPM governor and autorotation.
|

|
## Helicopter Types
|
|
|
|
PX4 supports helicopters with a single main rotor with a swash-plate controlled by up to 4 swash-plate servos, and:
|
|
|
|
- a mechanically uncoupled tail rotor driven by an ESC, or
|
|
- a mechanically coupled tail controlled by a servo on the tail motor.
|
|
|
|
The allowed flight operations and [flight modes](../flight_modes_mc/index.md) are the same as for multicopter.
|
|
Note however that (at the time of writing) 3D flying with negative thrust is not supported in autonomous/guided modes.
|
|
|
|
## 조립
|
|
|
|
Assembly of the core autopilot components are similar for all frames.
|
|
This is covered in [Basic Assembly](../assembly/index.md).
|
|
|
|
Helicopter-specific assembly consists mostly of connecting and powering the motors and swash plate servos.
|
|
|
|
:::info
|
|
Note that the flight controller cannot power motors and servos (only GPS module, RC receiver, and low power telemetry modules can be powered from Pixhawk flight controllers).
|
|
Generally a power distribution board (PDB) is used to power motors, and a separate (or integrated) battery elimination circuit (BEC) is used to power each of the servos.

## 설정
|
|
|
|
Helicopter configuration and setup is covered in:
|
|
|
|
- [Helicopter configuration](../config_heli/index.md): Vehicle frame selection, actuator configuration and testing, and tuning.
|
|
- [Standard Configuration](../config/index.md): The common configuration and calibration steps for most frames.
|
|
This includes configuration/calibration of core components such as compass and gyroscope, setting flight mode mappings on a remote control, and safety settings.
|
|
|
|
## Frame Builds
|
|
|
|
None available.
