Tutorial - Setup | Rotorflight

Arming is a safety feature that checks a series of settings in the FC to make sure it is safe before allowing it to spool up. It checks for things like accelerometer calibration, gyro filtering, throttle not at minimum, RX not connected.

Introduction

📄️ Backup and restore

Back up the configuration

📄️ Flashing the firmware

Install Rotorflight Configurator

📄️ Remapping

Rotorflight is based on Betaflight which is generally used to control drones. Unfortunately, drones do not have servos and have more motors than we need for a helicopter. In order to use servos we must remap our boards so that we have a pad to connect the servos to.

📄️ Servo Setup and Calibration

Step 1 - set frequency and center

📄️ Mixer Setup and Calibration

Before starting on this step the Servos should already be connected and calibrated.

📄️ RPM Measurement

In order to use the Governor or RPM filters (and why wouldn't you!!) you must measure the RPM. There are two options for this:

📄️ Governor

The purpose of the governor is to maintain a constant headspeed regardless of flight inputs, flying conditions, battery voltage, external disturbances, etc. In Rotorflight, the governor also provides other motor related features, like slow spoolup, autorotation control, battery voltage drop compensation, and fault detection and recovery.

📄️ Governor setup

There are several options for configuring the Governor.

📄️ RPM Filters

Introduction

📄️ ESC Telemetry

The purpose of ESC telemetry is to provide a method of reading the values provided by the ESC. These are things such as RPM, Temperature, Voltage, Current and mAh consumed. This is accomplished by connecting the ESC telemetry wire to the flight controller with a spare UART.

📄️ ELRS Telemetry Reuse

The Crossfire Protocol (CRSF) used by ELRS does not include the full range of sensors that can be useful for rotorflight. Crossfire was specifically designed for Drones, which generally have different parameters that are useful to the pilot.

📄️ Adding an extra servo

Add an extra servo controlled by an AUX channel.

📄️ Two-Stage Gear Train Ratios

Having an accurate gear ratio for the main and tail rotor is essential for Rotorflight accurate RPM Filters performance.
