Now that you have configured the settings, it is worth checking that is is working properly at this point.

⚠️Note: If you are unsure of the type of receiver you are using, you can select one and see if this is the correct one – this will not break your FC at all. Once done press the save and reboot button to apply the settings. Select the appropriate receiver settings in Betaflightĭepending on which receiver you are using, select the appropriate options from the two dropdown menus. if your quad is pointing ‘forward’ and this isn’t replicated on screen, don’t worry about it. SPEKTRUM1024 or SPEKTRUM2048 depending on your exact receiver modelĬRSFDon’t pay attention to the absolute position of the quad on the screen i.e.

Then select the Serial Receiver Provider to one of the following (dependant on your receiver type):.

First select the Receiver Mode to Serial-based Receiver.

To finalise your receiver setup, you then need to go to the ‘Configuration Tab’. In scroll down to the receiver section where you will need to tell betaflight what type of receiver you are using. Once selected don’t forget to save the settings. In this picture shown, we are using a FrSky SBUS receiver (the X4R) and so we have enabled the Serial RX on UART6.

You can have a look at your FC manual for the pinout of your board to gain this information. The important thing here is that you will have to enable it on the corresponding UART port that your receiver is connected to. receiver, you will need to go to the ‘Ports Tab’ to enable the the ‘Serial RX’ column. SBUS/IBUS/DSM Receiver (Serial Receiver) Ports Configuration Screen in Betaflight Don’t forget to hit the Save button in the bottom right of the screen to apply the settings. Assuming that your receiver is connected to the correct PPM in pin on your flight controller, and it is bound to your radio, it should now work. All you need to do is go to the ‘Configuration Tab’ and scroll down to the ‘Receiver’ section and select PPM RX as the receiver type. PPM ReceiverĬonfiguring a PPM receiver in betaflight is very easy.

Once you’ve established what type of receiver you’ve got hooked up to your quad, you can go to the corresponding section below to see how to set it up in betaflight. 📖 If this is like another language to you, check out our R/C receiver protocols guide! It is important to know this, as the settings are specific to each receiver. For FlySky, it’s likely to be PPM, SBUS or IBUS, and for Specktrum, you will have either DSM2 or DSMX. If you’ve got an FrSky receiver, you’re likely to have either a PPM or SBUS receiver. So, what receiver are you using? You are likely to be using one of the following brands: FrSky, FlySky or Spektrum. We’ve also created several little guides that should help to take you through these processes: Otherwise, none of this will work… If you are unsure how to do this, check out your receiver and/or radio manual. Before following the procedure I’m about to set out, please make sure that your receiver is bound to your radio transmitter, and correctly connected to your flight controller. Next, we’ll move on to setting up your receiver on your quad. Remember to hit ‘Save and Reboot’ after you make the change, otherwise it’ll reset to defaults after you move off the tab. A useful tip is to use the drop down box to select a preset angle offset.

You can correct it by trial and error if you don’t know the correct degree change instantly. So if the model on screen rolls when you pitch the quad forward, you will need to change the yaw degree by 90 degrees. The most common correction needed is to add some Yaw offset. You will then need to change the angle (in degrees) until the model moves correctly. This is done in the ‘Configuration’ tab and, more specifically, in the ‘Board and Sensor Alignment’ box. If not, you will need to tell BetaFlight the correct orientation. If everything looks correct here you can move onto the next step. ⚠️Note: The green arrow on the 3D render should be on top of your quad and indicates the forward direction of your quad in real life – it may not point in the same direction as your quad, however, as long as your quad tilts in the correct direction relative to these two reference points (you tilt forward and the green arrow tilts forward) you’re okay.

So if you tilt it down, the 3D model should also tilt down.

This should move correctly in relation how you move it in real-life. If you head over to the ‘Setup’ tab, you will see a 3D model of your quad in the middle of the screen. This could be incorrect at first because the flight controller may be mounted upside down, back to front, or otherwise misaligned. It is also a essential to check that BetaFlight knows the correct orientation of your quad.
