Are you feeling too lazy to walk and pick up your downed drone? Try Turtle mode! With a flip of a switch, it turns over your upside down quad so you can take off again.
Note: “Turtle mode” was renamed to “Flip Over After Crash” in later Betaflight releases, but most people still refer to it as Turtle mode.
Limitations of Flip Over After Crash
Turtle mode is an awesome feature to have on most drones, especially on brushless tiny whoops if you mostly fly indoor. However, it doesn’t work on brushed tiny whoops, because DShot isn’t supported by brushed motors.
Turtle mode works well on flat surface such as concrete, not so well on grassy fields especially when the props are obstructed.
In order to use the turtle mode, you need:
- Betaflight 3.2 or newer on your flight controller
- DShot compatible ESC (All version of BLHeli_32 ESC’s and BLHeli_S ESC with firmware 16.67 or newer)
- Latest version of Betaflight configurator
How to Setup
In Betaflight Configurator, Configuration tab, select DShot protocol (DShot150, 300 and 600 all support turtle mode).
Move over to the Modes tab, and assign a switch on your radio to “Flip Over After Crash”.
“Flip Over After Crash” option would be missing and won’t appear until you have selected DShot Protocol.
Finally, in the Configuration tab, set “Maximum Arm Angle” (Arming) to 180. Alternatively you can simply disable ACC (Acceleronmeter) if you don’t fly in Angle mode. This allow the drone to arm even when it’s upside down.
How to Use Turtle Mode?
- When the quad is flipped over, disarm
- Switch on Turtle mode, then arm it (motors should NOT spin, yet)
- Use your roll stick, the motors will start to spin and flip the quad over; the longer you hold the roll stick, the more thrust it will generate
- Once turned over, disarm immediately and turn off turtle mode
- Now arm the quad again to take off
You might want to practice this on a flat surface, clear of people. DO NOT overuse and force it if you can’t turn the quad over, it could burn out the motors and ESC’s.
Other Uses of Turtle Mode
It might help to get your quad out of a tree if it gets stuck, as it spins the motors the opposite direction. But if the props are tangled up, do not use turtle mode!
Some advance drone builders also use turtle mode to test motors. When the quad is sitting up right on the table, and the motors are spinning the opposite direction, they push the quad down so it will stay and not take off. However we don’t recommend doing this :)
