Hi all, I bought a PNP drone called the emax cinehawk. Im trying to program it for the first time. I flashed it successfully but not sure how or what to program after. Can someone help? I can even share my screen through a video call to make it easier.

What is the end goal?

#

To get it flying? If so, it'll depend on what receiver you got, the settings will be slightly different. But general thing is to

  • In the Ports tab, set the "serial RX" option on the UART port that you connected your receiver to
  • In the Configuration tab, set the receiver protocol
  • In the Receiver tab, check that you're getting stick inputs from your controller

If you don't, check that your receiver is bound to your radio properly

My setup:

PNP Drone: https://www.getfpv.com/emax-cinehawk-o3-3-5-drone-no-fpv-system-dji-pnp.html
Main Board: Main Board: EMAX F41125A AIO
Receiver: BetaFPV ELRS Lite Receiver Flat Antenna V1.1
DJI FPV Air Unit (1st one)
DJI FPV Goggles 2
DJI FPV Remote 2

Yes the goal is to get it to fly, this is my first drone build. How do I even know if my receiver is connected or not? What should I set my receiver protocol to?

you can technically use the 03 as a receiver, but it isn't recommended, because then the control and video links are tied together, plus the DJI controllers kinda suck compared to edgetx ones

but if you've just got a dji controller, we're stuck setting that up and using that until the ELRS controller you're about to order arrives

#

have you soldered the elrs receiver in?

#

also the flat antenna receivers are quite short range, you probably want a better one

Yes everything is soldered up. I can power it up with a battery and the ELRS receiver blinks blue. The air unit I have is the first one by DJI.

#

Ok, do you have an ELRS transmitter?

native grail
#

Yes, its soldered up and lighting up blue blinking when powered up with a battery

Did you just buy it or did you already have it

I had the entire dji fpv kit that had the remote goggles and drone.

I had a feeling the remote was not compatible with the ELRS. Is there a receiver that would be or should I just buy the black dji remote

The only one I know of is the o3 air unit

#

It has a receiver built in

#

But it’s not great

#

I’d more recommend getting an ELRS radio. The Radiomaster pocket crush is fairly cheap
