Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.

When using a separate battery for the video system on board the plane, does anyone know if there is any advantage to having the electrical grounds of both the flight system and the FPV system tied together?

I am using a small 3 cell lipo for the vid Tx and camera.

The main flight batt 3 cell lipo powers the RC Rx, (thru a 10amp BEC), flight servos and P&T servos, and of course the ESC and motor.

Thanks

As a good rule, the more isolated things are from each other the better. So don't link the grounds unless you really have a reason to (like an OSD measuring main batt voltage, or the R/C RX controlling something on the video side).
