Rotorflight Lua Scripts for Ethos

Rotorflight is a Flight Control software suite designed for single-rotor helicopters. It consists of:

• Rotorflight Flight Controller Firmware
• Rotorflight Configurator, for flashing and configuring the flight controller
• Rotorflight Blackbox Explorer, for analyzing blackbox flight logs
• Rotorflight Lua Scripts, for configuring the flight controller using a transmitter running:
  • EdgeTX/OpenTX
  • Ethos (this repository)

Built on Betaflight 4.3, Rotorflight incorporates numerous advanced features specifically tailored for helicopters. It's important to note that Rotorflight does not support multi-rotor crafts or airplanes; it's exclusively designed for RC helicopters.

This version of Rotorflight is also known as Rotorflight 2 or RF2.

Information

Tutorials, documentation, and flight videos can be found on the Rotorflight website.

And many more...

Lua Scripts Requirements

• Ethos 1.1.0 or later
• an X10, X12, X14, X18, X20 or Twin X Lite transmitter
• a FrSky Smartport or F.Port receiver using ACCESS, ACCST, TD or TW mode

Tested Receivers

The following receivers were correctly working with an X18 or X20 transmitter.

• TD MX 1.0.10
• R9 MX ACCESS 1.3.2
• R9 Mini ACCESS 1.3.1
• Archer RS ACCESS 2.1.10
• RX6R ACCESS 2.1.8
• R-XSR ACCESS 2.1.8
• R-XSR ACCST FCC F.port 2.1.0
• Archer Plus RS and Archer Plus RS Mini ACCESS F.Port 1.0.5

Note: when saving changes fails, the scripts will automatically retry. The R-XSR and the Archer Plus RS (Mini) seem to retry regularly, while the other receivers rarely do this.

Installation

Download the latest files (click Code and then Download ZIP) and copy the RF2 folder to the scripts folder on your transmitter. You will know that you've done this correctly if the Rotorflight 2 tool appears on the Ethos System menu.

Copying the RF2 folder

USB Method

1. Power on your transmitter
2. Connect your transmitter to a computer with an USB cable
3. Select Ethos Suite on the transmitter
4. Open the new drive on your computer
5. Unzip the file and copy the RF2 folder to the scripts folder on the SDCARD drive
6. Eject the drive
7. Unplug the USB cable
8. Turn off the transmitter and re-power it

SD Card Method

1. Power off your transmitter
2. Remove the SD card and plug it into a computer
3. Unzip the file and copy the RF2 folder to the scripts folder on the SDCARD drive
4. Eject the SD card
5. Reinsert your SD card into the transmitter
6. Power up your transmitter

Usage

See the Lua Scripts page.

Origins

Rotorflight is software that is open source and is available free of charge without warranty.

Rotorflight is forked from Betaflight, which in turn is forked from Cleanflight. Rotorflight borrows ideas and code also from HeliFlight3D, another Betaflight fork for helicopters.

Big thanks to everyone who has contributed along the journey!
