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.

Need quick answer, what is minimum optimum distance for rx and tx on a

Recommended Posts

Ok, sorry if it's been asked before, don't have a lot of time to go searching through database or google, so hoping one of ya guys knows the answer.

Am building giant wing, putting both video tx and rx on opposite sides of the wing. Wondering what the optimum minimum distance from centre(electronics, camera, anyvolt, batt, esc etc) that would work out well. Yes I know I should put them right at the edges of the wings, but looking to keep weight near the front so I don't have to add too much ballast as right now it looks like I need to add a lot to the nose.

The short answer is no, I have never used any of those.

It all depends on how good the spektrum is at rejecting the 900Mhz and how clean the 900Mhz output is.

With my 459Mhz and 2.4Ghz I find 6 inches is plenty.

Set it up and test it on your work bench if you need a definitive answer for your particular equipment. I don't think your setup would be any different than Terry's and would have the same results......

You also need to ve careful about the wiring. Distance alone isn't the only factor, if some wires are run in the way they act as an antenna they can catch the RF signal and conduct it to the receiver again even if it's on the other side. That's why there's no answer to your original question, the only real answer comes by trial and error.

Ok that I hadn't heard of before, wires are pretty much opposite from each other, one side for receiver, other to tx. Was flying zagi the other day, came up with yet another issue, I've been googling for a while and haven't seen a way to protect prop for a zagi style wing. I really don't want to rely on prop saver nor having to catch each time. Unrelated question to thread but anyone see a way of protecting prop?
