Latest FAQ

I get video, but the screen is black.

First off lets discuss how the image gets to your goggles! The video signal comes from the camera to the flight controller via the video in pad, then the OSD is overlaid over the image and the combined picture is then sent out the video out pin to the VTX which then transmits the signal to your goggles. If you are receiving a black screen, then that means the VTX is powered, and you are on the right channel in your goggles or monitor. However the VTX is not getting the video signal from your camera! A couple things to check,

  • Is your camera getting power?
  • Check the signal wire from the camera to the FC as well as solder connections. Make sure it is connected to Video IN!
  • Swap to a different camera.

If you can activate and see the OSD, this means the video out from the flight controller is working properly. If you can not get the OSD to open, then the video out from the FC may be the issue.

My video is all snow!

If you are only getting snow for your video this could mean a couple things.

  • 1 VTX is in Pit Mode
  • Goggles are on a different channel then what you have the VTX set to
  • The VTX is not powered.

If the VTX was working and you are on the correct channel, then you would get at least a black screen. For this problem check the goggles and make sure you are on the same channel as the VTX. Make sure the VTX is powered, there should be some kind of indication like a LED on your VTX. Maybe try swapping a different VTX.

My Flight controller only powers on via USB.

If you plug in the flight battery and there are no LED’s glowing on your FC, but when you plug into the computer you do get LED’s, you may have blown your voltage regulator. A voltage regulator takes the battery voltage and drops it down to 5V to power the accessories on your flight controller. There are then more regulators that drop that to 3.3V to power the MCU, or brains of the board. The MCU is the biggest square chip on the board.

If this has happened to you, Preston has made a video of how to remove the voltage regulator and then use an external 5V BEC which you can purchase on line to power the FC and accessories. You may also be able to use 5V from your ESC if your ESC has a 5V BEC. If you are going to use an external BEC, make sure it is rated for at least 2A.
