Order Number: 683040
Product Name: Neutronrc Mini F435 5-In-1 Aio Elrs Flight
Brand: NeuronRC
The problem seems to be with the onboard VTX. There appears to be a mismatch or interference with the video signal across channels — both in Betaflight and iNav. Initially, I thought it might be a configuration issue with iNav and the IRC Tramp protocol, but after further troubleshooting (including testing under Betaflight), I’m still seeing irregular frequency behavior. The goggles aren’t able to consistently pick up the video feed, and the available channels seem offset or misaligned.
I’ve tested my goggles separately with other VTXs, and they’re functioning normally, so I don’t believe the issue lies with the goggles themselves.

Thanks for getting in touch, and again, my compliments on the excellent troubleshooting you’ve done.
I’ve just dug deeper into the order details for 683040 and can see you’re right, the order is from over a year ago. This unfortunately means it’s now outside of both our standard 6-month warranty and the manufacturer’s 1-year period for a free replacement.
However, a component failing like that is still a real shame, and we don’t want this to leave you grounded. We really value you as a customer and want to help you get a working quad back in the air without you having to shoulder the full cost of a new board.
What I’d like to do is offer you a 15% discount on a new AIO flight controller from our stock, just let me know which one you would prefer.
As another potential option, since the flight controller and ELRS receiver part of your board is likely still working perfectly, you could just disable the faulty onboard VTX in Betaflight and wire in a tiny, separate VTX (like a PandaRC Nano or similar). It would involve a little extra soldering to the board’s power and video pads, but it could be a cheaper fix if you’re comfortable with the idea.
Let me know what you think. If you’d like to go with the discount, just reply to this email with the FC you would like to order, and I’ll generate a one-time code for you to use on our website.
Again, I’m sorry the board didn’t last as long as we’d all hope, but I hope one of these options works for you.
Thanks again for getting back in touch — I really appreciate the compliment on the troubleshooting. It’s been a bit of a long-winded process getting to this point!
Shame about the warranty period — as I mentioned, the board’s just been sitting in a box waiting for me to get around to a build, but I suppose that’s just how it goes sometimes. Still, I really appreciate you trying to help get me back in the air.
I’d definitely like to try and work out a path forward for getting a new flight controller into the build. One of the key requirements is that it needs to be compatible with iNav, as that’s what I’ve been planning to run on this setup. I also need at least 20A per motor, and ideally it would be an AIO with integrated VTX and ELRS — minimum 400mW output, and as lightweight as possible.
If that kind of all-in-one board isn’t available, I’m totally open to going with a 4-in-1 ESC and separate VTX and receiver. In that case, I wonder if you’d be open to applying the discount to just the flight controller portion — I’d be happy to cover the cost of the VTX and RX separately.
I’ll have a look on your website now and see what FCs are currently in stock. I’ve been working through a few spares I had in storage for a while, but I’ll take a fresh look and get back to you shortly if I see something suitable.
As for the other option you mentioned — disabling the onboard VTX and wiring in a separate one — I may still try that route, but part of the trouble I’ve run into with this specific AIO is that the pads which control VTX power are linked to the onboard ELRS as well. So disabling the VTX ends up disabling the receiver too, which kind of defeats the point. It feels a bit wasteful needing two extra modules just to replace one half-functional component.
To be honest, your first suggestion sounds more appealing at this point — I’ve seen enough of this board for a while, if you know what I mean.
Thanks again for all your help so far — I’ll check the available options and let you know what looks promising.
Thanks again for your patience and effort!
I just wanted to follow up and see if you had found any suitable replacements you liked the look of? As for your question regarding AIO versus stacks, let me know what you would like and I can speak to Alex about it.
We have these in stock currently, it only does 12A but these have had a lot of good feedback:
I hope this helps.
If there is anything else I can assist with please do let me know.
Unfortunately I can’t find anything in stock at the moment. I think to be in with a chance of finishing this build deadline I may have to order elsewhere for the AIO unfortunately. Annoying as I try and use you guys whenever possible.
Really appreciate your support and ongoing work to rectify my issue.
I hope there is a silver lining on the horizon.
All the best,
Heddwyn
