How to Customise the FN Button Function on DJI Drone
Peter Leslie
22 May 2026
If you are reaching across the screen mid-flight to recentre the gimbal or to flick on Cruise Control, the shortcut you are looking for is Button Customization inside DJI Fly. The FN button sits on the rear of most current DJI controllers for exactly this reason, and the binding takes ten seconds on any drone running DJI Fly.
Drones this applies to
Any DJI drone paired with a controller that has an FN button — the DJI RC-N3, the DJI RC 2, and the DJI RC Pro all carry one. That covers the DJI Neo 2, DJI Mini 5 Pro, DJI Air 3 Pro, DJI Avata 2, and DJI Mavic 4 Pro when flown on one of those controllers. The basic DJI RC and the DJI Motion Controller 3 do not have a dedicated FN button, so the row in DJI Fly will not appear when those are the connected hardware.
Quick guide
To customise the FN button on DJI Drone, go to DJI Fly → Settings → Control → Button Customization. Pick a function for single press, switch to the double-press tab, pick a second function, and DJI Fly saves the binding immediately.
Step-by-step: How to Customise the FN Button Function on DJI Drone
Follow these top to bottom the first time, and you will know the path off by heart the second time. The labels and order are identical on every drone in the callout above — the screenshots are taken on a DJI Neo 2.
Open the DJI Fly Settings menu from the camera view
With the drone powered on and connected to the controller, tap the Settings icon in the top right of the DJI Fly camera view. The settings panel slides in with the category tabs down the left.
Tap the Control category in the Settings panel
Control is the tab that holds gimbal, stick, and remote controller behaviour. Tap it and the right-hand pane updates to show every controller option for the connected drone, including the row you are looking for.
Scroll down inside Control until the Button Customization row appears
Scroll past the gimbal mode block and the stick mode block. The Button Customization row sits further down the Control list, with the binding screen opening when you tap the row.
Select the single-press tab inside Button Customization
Button Customization opens on two tabs, one for a single press and one for a double press. Start on the single-press tab — that is the one you will reach for most often in flight.
Pick a function to bind to a single press of the FN button
The single-press list covers Cruise Control, Recenter Gimbal, AE Lock, Switch Camera Mode, and the other shortcuts DJI thinks belong on a hardware button. The exact options vary slightly between drones. Tap the function you want and DJI Fly saves the binding straight away — there is no separate Save tap.
Switch to the double-press tab inside Button Customization
Tap across to the second tab to set a function for a double press. Single press and double press are stored as separate bindings inside the same screen, so changing one never overwrites the other.
Pick a second function to bind to a double press of the FN button
Choose a function that pairs sensibly with whatever you set on single press. Recenter Gimbal on single and Cruise Control on double is a clean combination across most drones — the gentle action gets the easy tap, the heavier action takes the deliberate double.
Exit Settings and test both bindings on the ground before takeoff
Back out to the camera view and press the FN button once. Watch DJI Fly fire the single-press function, then press the button twice in quick succession and watch the double-press function fire. Five seconds on the ground saves a surprised tap in the air.
Peter's tip
I keep single press on Recenter Gimbal and double press on Cruise Control across every drone I fly. The gentle, low-stakes action gets the easy tap; the action that takes a finger off the sticks gets the deliberate double press. Pick a pair, stick to it across every drone, and your muscle memory does the work — swapping bindings between flights is how you mash the wrong function at the wrong moment.
Frequently asked questions
Which DJI controllers have an FN button?
Not every DJI controller has one. The DJI RC-N3, the DJI RC 2, and the DJI RC Pro all carry a customisable FN button on the rear or the side. The basic DJI RC and the DJI Motion Controller 3 do not have a dedicated FN button — on those controllers the customisable shortcuts are bound to different hardware (the dial on the RC, the camera trigger on the motion controller). Check the back of your own controller before you go hunting for the row in DJI Fly.
What functions can I bind to the FN button on a DJI drone?
The Button Customization list inside DJI Fly covers Cruise Control, Recenter Gimbal, AE Lock, Switch Camera Mode, and the other shortcuts that have a sensible one-press use. The exact options shift between drones and firmware versions — a DJI Mini 5 Pro lists a different set to a DJI Avata 2 — so open the menu yourself to see the current list for the drone in your hand rather than relying on a screenshot from another model.
Can the FN button do two different things on single press and double press?
Yes. DJI Fly stores the single-press function and the double-press function as separate bindings inside the same Button Customization screen. A common setup is single press for Recenter Gimbal and double press for Cruise Control, which gives you two shortcuts off one button without ever taking your eyes off the screen.
Does the FN button binding survive a firmware update?
In most cases yes, but a firmware update occasionally reshuffles the available functions or resets the binding back to default. Open Button Customization once after every firmware update and confirm the single-press and double-press functions are still the ones you wanted. It is a ten-second check that saves a surprised double-tap in flight.
Why can I not see the Button Customization row in DJI Fly?
The row only appears when DJI Fly is connected to a drone through a controller that has a customisable button. If the drone is powered off, if the controller is paired to a different drone, if the app is sitting on the home screen rather than the camera view, or if the controller does not have an FN button to begin with, the Control menu hides the row. Power the drone on, confirm the link, and reopen Settings from the camera view.
Does the binding follow the drone or the controller?
It follows the controller and the DJI Fly profile, not the drone. A friend who borrows the drone with their own controller and phone gets their own defaults. If two drone pilots share the same controller and phone, the last binding saved is the one in force — agree the shortcut between you before takeoff.
Does the FN button work the same way across all DJI drones?
The menu path is identical on every drone running DJI Fly — Settings, then Control, then Button Customization. What changes between drones is the list of functions you can bind. A DJI Avata 2 exposes FPV-relevant shortcuts; a DJI Mini 5 Pro leans toward camera and gimbal controls. Pick the function from the list the drone in front of you offers, not from a tutorial filmed on a different model.
Can I reset the FN button binding back to default?
Yes. Open Button Customization and tap the function the drone shipped with — usually Recenter Gimbal on single press and no binding on double press. There is no separate reset button; choosing the original function is the reset. A full controller linking refresh from the Control menu also restores defaults on most current drones.
A custom FN button is one of those DJI tweaks that costs nothing to set up and pays back on every flight. Pick a single-press function, pick a double-press function, fly the same pair every time, and the muscle memory does the rest.
If your Button Customization list looks different to mine, or a binding refuses to save, drop a note to peter@hiredronepilot.uk with the drone, the controller, and the DJI Fly version you are on and I will come back to you directly.
