Hello gang,

I have an iFlight Nazgul5 4s version that I have been flying on a 5s, although I’ve gotten a bit of noise that a 400uF 50v took care. Recently, I’ve upgraded the motors to handle 6s, but I’m running into issues with the video transmission.

When using a 6s the VTX would cut off in split seconds during load and comes back to normal when I ease off the throttle.

Here’s the stack that it came with:

Main Flight Controller: SucceX-E F4 (BETAFLIGHTF4 Firmware)
-ESC:45A 2-6S BLheli_S DShot600
-FORCE VT5804 V2: 0/25/600mW Adjustable frequency 48CH with IRC protocol.


Since this rig is rated 4s is there a way to change the voltage output to accept 6s?

How are you powering the VTX? Directly from battery? Are you sure its not the FC OSD that cuts out the signal? Did you try to run video directly from cam to VTX?
(I had a similar problem once and it was the FC)

Check to make sure, but I think your VTX can handle 6s. If it can, the first thing I would try is powering it straight from the battery and bypassing the board. Then, as @Wrecked mentioned, you can try running the camera signal straight to the VTX and bypassing the board that way too (you'll lose OSD this way though)

Hello gang,

Here's an update. The stock wiring configuration on the Nazgul5 came cabled and neatly plugged to the aio. I was doing a bit more research and ran across this video that helped me out a bit.

Here's what I did that eliminated the cutouts during throttle punchout, I eliminated the camera wires that were connected to the FC and ran it directly to the VTX and for me to get the OSD telemetry back, I soldered to the TX1 (setting things up in BetaFlight ports took me a while to figure things out, I had almost given up thinking that I rewired things incorrectly, but thankfully I sorted things out)

Thank you for hint and tips @Wrecked and @rtkDarling
