I’m currently building a Heewing V1 VTOL plane and I’m experiencing issues when connecting my radiomaster pocket.
I have a RP1 radiomaster ELRS receiver and a ELRS radiomaster pocket, I had to change the coding so my receiver in is at port ‘UART2’ and thankfully it’s worked and my receiver is showing a solid green light with Telemetry found.
On mission planner however radio calibration isn’t showing me the bars go up and down when I move the sticks.
My radiomaster pocket says model mismatch 5.
I’ve attached photos, if anyone knows how to get it to work on radio calibration it would be greatly appreciated.
Still nothing on radio calibration. My radiomaster pocket is bound, the only other thing I can see on the aircraft is a blinking red light above port UART1 and I’m unsure if that’s stopping any signals being sent.
I’m not even using that port so I don’t think it would be the problem.
I just find it strange how the controller is bound but I’m getting no feedback on radio calibration.
The only other thing I can’t seem to figure out is on serial ports my UART2 which is labelled serial port 6 says Speed 115200 which is correct but protocol is RCIN which is correct but not for CRSF. However under protocols CRSF isn’t available to select but I’ve manually done that in changing the value of serial 6 to 115 BAUD and 23 protocol.
That’s a mapping thing. It’s very common. I’m not into the code to explain why, but I’ll say it’s really common on a lot of flight controllers, you just have to be aware of it.
On the RC link the baud rate is automatically set so you don’t need to worry about that as long as the protocol is set.
Check the wiring. The RX of the receiver should go to the TX pin on the flight controller, and vice versa. TX <> RX, RX <> TX.
If you use the RCIN pin on the flight controller you’d need to change the receiver protocol in the ELRS script to SBUS. With that you won’t get any telemetry data back. It will work, but I’d rather go with at least the full ELRS/CRSF link so you get telemetry back to your radio.
Edit: Sorry, changed my mind. Looking at your photos again and I see it’s showing pitch roll and yaw as green. Do those values move when you’re connected?
There’s no GPS calibration, but you will need to do the compass. Do that with the plane outside with a GPS position. (auto calculates declination for you)
Your radio needs six outputs: (the first 4 are there, so really you just need to set up the last two)
1 - Aileron
2 - Elevator
3 - Throttle
4- Rudder.
5- Arm (This needs to be on channel 5 for ELRS)
6- Modes.
You need to set that up on the radio before you go any further. Look up RC Video Reviews on youtube. https://www.youtube.com/@RCVideoReviews He’s got a bunch of videos on how to set up your radio. Just set up the six channels I mentioned. Don’t worry about motors and outputs on the plane just yet, that’s set up in Ardupilot on the outputs and has nothing to do with the radio.
Okay thank you, I’ll set that up later and get back to you. Then try figure out the parameters for why the rear motor isn’t working/rudder. I’ll also attach screenshots.
Okay amazing, I’ve got the modes set up and the front two motors are switching from vertical to horizontal fine.
Final issue is the rear rudder isn’t receiving any signals or moving.
I’ve attached another file with a few things I think it could be. For example I’m missing ‘RUD’ on my radiomaster but I’ve searched forums and can’t seem how to add it, it won’t let me.
Possibly the fact it isn’t calibrated on my radiomaster pocket is the reason when I start the it up it doesn’t move?
You need to identify the stick input for yaw on channel 4. That should have been there by default. You should be able to do it by editing channel 4 on the input page on the radio. (IMG_5097)
