I’m building a quad-copter using a Kakute H7 controller, which has a chip for on-screen display. I also have a DJI Air Unit 03 VTX, but I don’t want to use the DJI remote controller. I have an ELRS receiver. I know I can leave the Air Unit’s SBUS and its ground disconnected, and use the ELRS for control. I’d like to know of a good radio controller that will use the ELRS for control and receive the video from the Air Unit for display on an attached phone or tablet (and work with Ardupilot/Mission Planner of course). If possible, it should also work with the on-screen display from the flight controller. Recommendations, please?
I hope someone more knowledgeable corrects me if I’m wrong but I don’t think there is an easy way to get the FPV video feed from the DJI O3 into Mission Planner.
There’s software called Cosmo Streamer which can stream the video from some DJI goggles into a computer or other device but I’m not aware of a way to incorporate this video into Mission Planner.
Are you also asking about a radio transmitter for the ELRS? If so, I really like the new Radiomaster GX12. I haven’t used it myself yet but I think it looks like a good radio. The Radiomaster TX16S is another good option. I like having multiple analog channels for things like gimbals. The TX16S has two analog knobs and two analog sliders for controlling gimbals and other things with more than three positions.
I believe it is possible for ELRS to be configured to send telemetry to Mission Planner. I don’t know how to do this myself but I think this is something being actively developed.
Many people add a dedicated telemetry radio which communicates with Mission Planner bypassing the control signal. For example, the ELRS radios may use 2.4GHz and 915MHz radios are used for telemetry.
Again, hopefully someone will correct any errors in my advice and hopefully they will expand on my advice with further recommendations.
The radio is the easy one. Any Radiomaster ELRS radio will work. The “best” is the one you like the most. TX16S, Boxer, GX12. They’re all fine. GX12 has the new Gemini module, but if you already have receivers you want to use that may not be a big deal. I like the TX16S because I fly pinch and I like the colour screen. My co-worker loves his Boxer because it’s more compact and fits his hands better. The Jumper T15 is also pretty appealing.
Video is the hard part. If you can find some way to get HDMI out then you can feed the video into the device via a HDMI to USB adapter. Mission planner will accept USB video (in windows). On android you may have to use QGC to get it done but it should work. I don’t know about the current gear, but in the past this has been very difficult with DJI.
Hello everyone,
I know this might be a new topic, but since this chat is active, I wanted to ask. I need to build a quadcopter that can fly up to the ceiling, hover about 1 foot below a smoke sensor for 30 seconds, and then return to its starting position. Is it possible to achieve this using Mission Planner?
just need the vertical movement
Can use one camera facing upwards to detect the smoke sensor?
Consider this one is indoor, so there’s no gps? I have to use vision control? can i use only one camera facing upwards is enough for stability ?
Thank you
Create a new post. That has nothing to do with this one active or not in any regard.
Duane and Allister, thanks for the advice. I will study your controller suggestions .As to the VTX, I am able to return the Air Unit and decided to buy an Avatar receiver, which has an HDMI output. CADDX has some of its digital systems on sale just now.
I didn’t want this to be another DJI vs Walksnail thread, but this was a significant reason I went with the Walksnail VRX to use it with Mission Planner and QGC.
I have had issues with some amazon HDMI to USB converters. Some work flawlessly, but a couple others I picked up cause the VRX to crash.
