Hey,

Is your stick mapping is right?

@tacit root you probably wanted to point to the BADRX error, strangely enough my min values in BF are at 989 and max values at 2012 for the stick although I have calibrated the radio again... but that can not be the cause of my problem or not ?

No radio in betaflight check if 3d mode in motor is off and I receiver tab check if you move stick if is right

and how close is the receiver antenna to any video wires/electronics?

I just powered up my vtx to 100mW, that improved the picture a little but the lines are still the if the radio connects to the receiver

Oh bith 5v

#

See if the lines change when you change telemetry ratio or packet rate

Powering a vtx from FC 5V is not very nice to the FC's 5V rail

#

What power level is the vtx running at?

#

Generally you want to have a vtx that runs off of a higher voltage

#

And has its own 5v output

#

So that it can be used to power the camera if the FC's 5V rail is too noisy

#

But that's just my opinion

Well, it runs off of 5V and is a reallllly ancient model

#

Hmm, 100mW shouldn't put too much load on the 5V rail...

#

You can try to put the camera on 9V if it supports that, but tbh I wouldn't be surprised if that just made it worse.

Higher made it better?

#

Huhhh

magic vault
#

yes...

hushed idol
#

Are you sure that the issue is on the drone side and not the goggle side?

#

i have the same kind of noise in my video feed if the elrs receiver enters AP mode and also if the FC is connected to usb...

magic vault
#

im using the Skyzone 04L V2

hushed idol
#

Hmm

Can you recommend an vtx with 5v output?
