Hey guys,
I bought the new happymodel mobula 7 HD and everything went fine. I bind the controller and start the flight but after 50-60 second the core temperature go up to 78-80 degree. Not the vtx temperature itself. then a warning goes on and the drone drops out of the air and the telemetry to the controller is lost and don't come back. I flew the drone in my kitchen so not far away.video is still there battery is fine. It's the new Aoi5 board from HDzero with 0802-25000kv
I have also a happymodel mobula6 HD with the Aoi5 board and there is everything fine.Something like this with the Mob7 never happened.
So maybe u guys have an idea or maybe had the same issue and know how to solve it.
Kind regards from Germany

So I got an email from happymodels with a firmware I reflashed everything and dump the preset he send me for the happymodel mobula 7 HD and now it works fine 😊👌
Thanks guys for ur helps
Sorry to hear about the trouble with your Mobula 7 HD. From your description, it sounds like the VTX might be overheating - especially if there was ever a moment it powered on without a fully attached antenna. That situation is basically a fast-track to damaging your VTX, since the radiowaves can’t properly dissipate. If that’s the case, you may need a replacement.
I actually ran into a similar problem during my own FPV journey; I shared some of those lessons in my post, My FPV Journey: From Abandoned Factories to Imperial March ESC Tunes. Give it a read - you might find a tip or two that helps you avoid more headaches. Good luck, and let us know how it turns out!
Changing the antenna unfortunately is not going to help. You could go into Betaflight settings, disable the vtx (by setting it's power to 0) and see if the fc still overheats. If it does, then you'll have to get a new one : (.
Yeah antenna was not working out.
I put the vtx on 0 and was flying around and it did the same after around 60 seconds it falls out of the sky and telemetry lost.
Yeah i think it's maybe the board.
That's unfortunate. On the bright side, you can use our catalog feature to make finding a replacement easier

Why are you focusing on board temp ? You can go into the osd tab display and turn off cpu temp warning.
It really means nout to us. I'd be more worried about hot motors or a not Vtx.
What failsafe do you have set up ?
What Rx protocol are you on ?
I think this can be fixed

@Sennad99 for future use : don't mark yourself as having solved issue. Would be more appropriate to assign it to @liquideath.
Good to hear you got it sorted.
Happy flying
Thanks for the tips I have some spare antennas so I try to change them and see what happens.
I will also read your fpv journal and maybe I find the solution.
The thing is it's not the vtx temperature who goes that hight it's directly the core temperature.
I fly my mob6 hd everyday in the flat anf the vtx temperature goes sometimes over 95 and it still arms end everything and never fall out of the sky.
I WI try now first a new antenna.
