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 was announced several months ago (March 2021) to allow our members ample 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.

  1. I should point out that I was using very directional aerials on the receiver which also cuts down the multipathing. Also the same setup did suffer problems one time when I put the tracker on the roof of my car as I was too lazy to set the tripod up so it easy to upset. CP seems to be the thing to go for if your building a new system as linear does not seem to give any appreciable extra range. Linear is simple though and does work for long range high flight with the right aerials. No matter which system is used I would always point the aerial out the bottom though if its practical to do so. Terry
  2. Or maybe FPV will fade into the background... Terry
  3. Yes I much more familiar with the helix but even a short one is quite long. I was looking for cp patches originally but so many are out of stock then I saw the half sphere but the price put me off so wondered how hard they are to make. Are they as effective as they claim? Why are they so expensive, is there something in them that is not obvious just by looking? Terry
  4. Im interested in testing one of these half sphere aerials. Is there a DIY version about? Where did this design originate? Any info welcolm Terry

    Lost Drones

    Unfortunately the marketing and general hype have fuelled a massive rush to make them the must have item this Christmas. Every shop seems to stock them with assistants that dont know the first ting about them. I was in my local camera shop the other day and commented to the manager about the DJI Phantom he had in his window and he told me straight that he didnt know the first thing about it. I know of parents that have got them for young children having been told they are easy to fly and they would soon get the hang of it. One Facebook mum has posted that her 14 year old son has lost his camera drone on the first flight and he is in the dog house until he finds it as it cost so much. Its is a sad mess.... Terry

    Lost Drones

    I have been amazed at how many drones have been reported lost over the last couple of days on social media. It seems children push the throttle open when things look bad and their self stabilising nature means they get carried by the wind for a fair distance before they go out of radio range and drop to the ground. I expect to see a lot of controllers on ebay soon which will be just the ticket for anyone who has found a drone. lol Terry
  7. Indoor flying sure does require CP and good diversity. Good to see the Oracle doing its bit. Sad to say mine has been sleeping for years! Terry
  8. Great work as always! If you manage to make a time expander I will be first to build it as I dont seem to find time to do anything these days. Terry

    GPS modules

    I wonder which I have, I expect it's the low cost version rather than the high performance version. do you think it would be possible to to connect both devices to the one module? Terry

    GPS modules

    I have just got a FY31 autopilot and a Remzibi OSD to get my old camera plane back in the air and I notice both use a huge 30mm square GPS module. Why the switch from the little modules that were used before? These are so heavy I would be interested to know what the advantage is. Terry
  11. I see where you are coming from, I remember a discussion about HD a few years back. If I remember correctly it was the bandwidth that was the main issue then? Years back I did sketch out a system to use 2 side by side standard systems similar to some of the computer screen surround gaming screen set ups now. The main difference was that by using prisms I could lose the bar where the 2 screens joined to make an almost perfect picture. I didn't pursue the idea very far as at the time I was mainly interested in using the camera feed to aim my stills camera for AP. The other problem that put me off taking it further was the inability to record in the wide format so it would only be any good for live viewing. A proper HD system would be far better so I will be watching with interest! Terry
  12. Ah OK. Thats me out, I like all of my gear to be interchangeable. I have a mini quad with a broken frame so making a new frame with somewhere to put the camera and TX may be a better option. Thanks for the info. Terry
  13. What frequencies does the video TX use? I'm tempted to get one to play with if it will work with my existing receivers. Thanks, Terry
  14. As a hobby level project I think it is the way to go but I think mainstream HD is going to happen anyway and will come from one of the big companies when it does. I also think they will want to side step the band width problems by going digital even if this means a little latency. I guess what I am saying is that the hobbies speed of progress has outstripped the DIYers for the most part. There is still room for the talented DIYer to do some fun stuff as you proof again and again but HD FPV in my opinion is not time well spent, its coming anyway. Terry
  15. Probably some clever guy at the company thought he would improve it....... Terry
  16. Thanks for that. I dont know why I had forgotten it was a 3db loss considering I built and used a helical back in the 2.4Ghz days. I may buy one (or two) to test as CP seems the norm these days. I did dust off my old Twinstar biplane the other day and it seems to have got me thinking.... Terry
  17. Not that I'm going to start building or flying anything just now but my mind was free wheeling to what was going to be my next auto tracker. Just out of interest has anyone done any field testing of the SpiroNet 5.8Ghz RHCP Patches? Are they good at rejecting linear signals? What is the real world increase in range compared to an omni? Thanks, Terry
  18. How times have changed! I must say I don't like the term drone, I'm not even over keen on FPV. Drone makes my think of big unmanned aircraft that the military shoot at and FPV makes me think of video games. I prefer to say camera plane/copter for aerial photography of video plane/copter with no stills camera. There were some great bits of kit developed at the time including the Inspire, sadly now that its gone plug and play it doesn't interest me. I had a look at some of my first videos the other day and was remembering how excited I was to see a grainy black and white image from my plane flying 100ft away! Terry
  19. It depends which country you live in and where exactly it is that you want but the world is flooded with cameras of all prices these days. Try ebay for cheap or dedicated FPV seller for a more suitable better quality set up. Terry
  20. Those SATA plugs have always looks a little flimsy to me. The drive to make everything smaller is not helping, in fact I have often hard wired rc servo leads for greater reliability Terry
