Hold switch damaged

Unfortunately my radio came so, any of you know how to fix or workaround? Even if I remove the cable always marks the contact.

What's the problem you're having?

Update that thing to Deviation 4.0.1 ASAP and enjoy it, I highly doubt anything's actually wrong, that's just the factory FW...

No, I have tried 4.0.1 deviation firmware and the last nightly firmware but hold button have an hardware contact in my opinion. Sorry for my English

I don't get it really too
Do you mean the fast switching values -100 / 100 on Hold1 and Hold0?

At the start of the video you can see that they switch multiple times.
You did not switch the hold1 manually, don't you?

yes, I'm talking about that, but not a quality ... I do not touch any switches, unfortunately does this Flaw, randomly, and even if I remove the connector of the switch does not change anything.

with the switch connected does it do this both in hold0 and hold1 states (i.e. does the randomness happen regardless of switch position)?

does the switch actually work at all? does changing the switch value change the output?

if you could take a high-resolution image of the circuit board it might help me compare to my own.

it is probably a bad solder connection or possibly a missing resistor. It is probably fixable with the right tools. But you should also contact Bangood, and see what they say.

If you want to keep it, you could instead do the switch mod, and then just ignore HOLD outright. It is not a difficult soldering job to do.

From my tests the switch works, is the board that makes a short circuit.

Also other switch have same problem?
Look a video... I don't know normal function.
But now, I can't use it for fly, change my command...
You understand?

Yes, but I haven't touched that part. I'm unlucky..

This looks a bit suspect, perhaps shorting to the SMD component just below it?

Bang_good will not help, since you have opened up the Tx, you have voided the warranty of the product.

unfortunately I'm here with the loupe to check, they one and the other point will highlight problems. If you want to place the detailed photos. You have to look elsewhere.

So, it is fixed now? What was the problem?

I do not know the normal operation. But by moving a single switch because it moves both Hold that FModE? If they are equal because you call them different? I think it's still broken. And the module has been removed to see if the problem was. However much the remote control is not used.



It bang_good rather not even deigned to respond. For two days I expect.
So for me personally, since money spent, time lost, to have a radio that if I ever get to run will have a range equal to the worst that I own ... Even if it costs 10 times as much ...
End here...

Ho controllato tutte le piste visibili. Il corto circuito è altrove.

I have check all visible track.
The short circuit is under something ...

Try using the channel monitor instead of the mixer output, to rule out any model programming error... and reflash the 7e with a nighlty build, just to see if anythig changes

Both unlikely, I know, but worth ruling out any software issue

I do not know what you mean. I already have a night version, my quad only work with that.

Just to make sure that you don't have some switch assignment/mixing errors in the instuctions of your model.ini file, load a blank model file.

From initial main screen, press ENT > go to "Model Menu" press ENT > "Model setup" press ENT > "Load" press ENT > use UP/DN switch to pick any file that says "None" press ENT.
Then press EXT 2 times, press DN to "Transmitter menu" press ENT > DN to "Channel monitor" press ENT > press R to go to "Stick input" > DN to view the switches in question, and view the results. If everything is good with the switches, then you have a switch assignment/mixing error in the model.ini file that you were using earlier when having the errors.

If that fails to correct your switch errors, I would try formatting the Tx drive to eliminate any possibly corrupted file that might be causing the error(don't forget to save your model files that you want to keep to your PC), download a fresh Nightly Build .zip from the website, flash the new .dfu to the Tx memory, and re-populate the Tx disc with fresh files from the new nightly build folder. ...then see if that fixes the problem.

If that does not fix it, then, most likely, you do have a hardware problem/short/defective main board. Whether it is an issue caused by your mods, (eg: ESD zapped component from not taking proper precautions against static discharge, or solder bridging of circuitry that should not be in contact with each other) or if it was just a bad Tx right out of the box from new, will be an unknown answer.
