Stick Commands for Betaflight, iNav, and HDZero OSD Menu

For FPV pilots, stick commands are an essential tool for changing settings of your flight controller or FPV system directly from your radio. These commands allow you to perform various functions, from navigating the OSD menu to trimming accelerometer, making them invaluable when you’re in the field without access to a computer. I will share the the stick commands diagrams for Betaflight, iNav, and HDZero, so you don’t have to memorize them.

What Are Stick Commands?

Stick commands are specific combinations of joystick movements on your radio that send commands to the flight controller (FC), enabling certain functions or activating the OSD menu.

Note: All stick command diagrams in this guide use Mode 2, the most popular radio configuration. If you use a different mode, you’ll need to adjust the diagrams accordingly.

What’s Mode 2?
In Mode 2, the left stick controls throttle and yaw, while the right stick controls pitch and roll. Learn about the basics of radio here: https://oscarliang.com/radio-transmitter/#Modes

Betaflight Stick Commands

The most commonly used Betaflight stick commands include:

• Enter OSD Menu: Hold yaw left and pitch forward.
• Accelerometer (ACC) Calibration: Hold throttle up, yaw left, and pitch backward. This is useful if you cannot perform ACC calibration on a bench using the configurator.
• Trim ACC: Use the four ACC trim commands to adjust errors in the accelerometer. This is particularly handy if your quad drifts in Angle or Horizon mode or if you calibrated the ACC on an uneven surface.

Pro Tip: Ensure you have full stick travel to access these commands. Your stick endpoints should ideally be at 1000 and 2000, with the center at 1500. If for whatever reason you can’t get to these numbers, Betaflight allows you to change these values in the Receiver tab, just adjust the “Stick Low,” “Stick Center,” and “Stick High”. But for most people the default values should work fine and don’t need changing.

iNav Stick Commands

Most iNav stick commands are similar to Betaflight’s since both projects originated from Cleanflight. However, iNav introduces additional commands for navigation-focused functions:

• Load and Save Waypoint Missions: Unique to iNav, these commands let you load or save pre-planned missions via the OSD menu without needing a computer.
• Compass Calibration: Throttle down, yaw right, and roll left. You might use this command more often in iNav than Betaflight, especially before GPS-assisted flights to ensure accurate navigation.

HDZero Stick Commands

HDZero FPV system includes a series of stick commands for its video and OSD menu. These include:

• Enter the HDZero OSD Menu: Access and adjust settings specific to HDZero.
• Video Output Mode Change: Switch output modes to adjust display preferences.

Conclusion: Why Stick Commands Matter

Using stick commands in Betaflight, INAV, and HDZero unlocks a level of convenience and control that enhances your overall flight experience. These commands allow for quick tweaks without needing a computer, making them essential in the field.
