Flight Controller Issues

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.

How to connect the DJI air unit to the RevoltOSD and OSD Lite

SO you bought the new DJI System and want to connect it to your Flight one controllers. There are a few things you need to know first. Currently this only works on FalcoX, and not all the OSD features are enabled and you must use the Falcox configurator found here to set up the quad. Flightone.com/alpha.

This image was done by one of our alpha testers, Nitro. We hope this helps clarify how to connect this system.

How to connect Crossfire to RevoltOSD and RevoltOSD Lite

As of this post it is recommended to connect crossfire in the following way. Currently telemetry is not supported in Falco so no need to connect channel 2 on the crossfire to anything. With this setup you will still get RSSI, which can be seen in another FAQ.

The recommended way is to connect channel 1 from the crossfire to the TX 1 pad on the FC. Then connect ground to ground and 5V to 5V. You must solder the TX1 jumper on the edge of the board to Normal.
