Attention: RC-CAM.com will permanently shut down on August-08-2021.

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.

RC-Cam'er (2/4)



  1. No dogs here, but you see the derivation of the name now! I thought the le Rhone rotary of Shuttleworth's Pup sounded much better than the Zenoah 26 that is actually fitted. Slightly crude dubbing but maybe in time my video editing skills will improve. I live in hope
  2. A day off work coinciding with some decent weather meant another PupCam mission was on the cards. I was interested to see how the autopan system was working after I had reduced the gain slightly. This resulted in ...... http://uk.youtube.com/watch?v=9Gu5pkesM0k I am quite pleased with how the system is working now but could still do with improving the video reception from the puny Tx output (no I won't be upping the Tx output). So I'm thinking about the possibilites of a DIY diversity receiver ultimately and higher gain Rx aerials initially. Options for the aerials include double bi-quad, Yagi and dish probably in that order. The bi-quad I'm using at the moment was dead easy to make so the double bi-quad should be pretty easy too. I understand some people have had very good results using Woks as parabolic dishes for WiFi systems which suits my budget and interest in putting things to unusual uses.
  3. But Phil, The big question is, was the video affecting the control quality?
  4. Hi Phil, The UnoWot's looking good and the results will be great. My first aerial video experiments used a board camera mounted on the port wing in a sort of nacelle thingy and it worked a treat. Boy did that UnoWot get some use! If you don't mind me saying, don't you think the colour scheme is just a little understated? I'm worried with such a low key scheme you might have trouble seeing it! Alan B
  5. Phil, It appears that some video devices do not have terminated inputs/outputs (75Ohm). My combination of video receiver and DVD recorder suffers from this with the net result being un-useable recordings. I found this out first time I used it in anger doing air to air with a fantastic 30% DH2 and I was not pleased! So I terminated the input with a resistor which made a big difference but actually the best solution was a potential divider between input and output and then set the video level into the recorder to 1v using a scope.

  6. You're right Terry, it is an unusual formation! There are plans a foot for some more likely combinations but looks like the weather might mean they take a while to come together. WRT the smoothness of the pan & tilt. I think it could really do with some sort of soft start to slow the initial movement. Don't want to just slow it down all the time as rapid movement is important when sweeping from one end to the other. Maybe the use of negative exponential on the controller might give the same effect (at least when in the centre of the travel)
  7. After literally years of messing about, sorry I meant to say painstaking work, here is a video of the latest results from my attempts at R/C air to air video. The subject is a rather nice Lancaster bomber belonging to a friend. http://uk.youtube.com/watch?v=9RhBxrtSb6w It was taken from a 1/4 scale Sopwith Pup using my Mk 3 PupCam system which is described on this build thread http://www.rcmf.co.uk/4um/index.php?topic=38640.0 At last it seems to be coming along quite nicely, but the logistics of a flying session are just horrendous! Two pilots, one camera operator, one aircraft tracker, all the kit and so many batteries to charge!
  8. I'm back! OK so this experiment has been a long time in the making. Built a new version of the camera mount which includes a HAL2000. Did a build thread on my 'local' forum which might be of interest. Video of the first test of the AutoPan and some air-to-air stuff at the end of the thread. Video quality of the AutoPan clip is not great. My excuse? No one to track the aeroplane with the receiver. Still it shows the HAL system works and that I need to improve my flying with better coordinated turns. http://www.rcmf.co.uk/4um/index.php?topic=38640.0
  9. It is probably best to use a video buffer of some sort (I think Mr RC-CAM has described one somewhere) although I have got a away with just a simple Y lead on occasions. Try it and see! Another option might be available if the video recorder video out is active during recording. In that case Rx signal to recorder video in, recorder video out to glasses. If you need/want to go the seperate video buffer route I might be able to find a simple circuit if necessary. See how you go.
  10. Here is information on my "hacking" of a 148 servo to give 540 degrees of rotation if you are interested: http://uk.geocities.com/tulyar-AT-btinternet....om/ServoMod.htm
  11. Hi, Can I mention the Mustek PVR-A1 again? Pros: Very small (you can even carry it onboard if the plane is a reasonable size) Cheap (Cheapest price I've seen in the UK is about £80 - www.cpc.co.uk) Complete with USB lead and software to connect to any USB equipped PC Can use Windows Explorer to transfer files from PVR-A1 Uses SD memory cards Is is also an MP3 and jpg player Same resolution (I think) as the cheaper video grabbers I've tried eg Dazzle DVC80 Cons: Low resolution (340x220) Software is not fantastic but it does the job (only need to transfer files from PC to the PVR) The best, most practical, solution in my opinion is a good digital camcorder with analogue input because of the quality of the capture and then the ease of transfer and editing on the PC. However if budget is your main driver then it's got to be the PVR! (No - I have no connection with Mustek other than as a satisfied customer ....)
  12. Crash Pilot, Although I have little experience of electric flying, no electric AV and I don't know the your aircraft(!) my view is that I would run the AV gear from a seperate supply. Because of the high capacity of AAA and AA cells these days you can get a very reasonable duration (depending on the load of course) from a small, lightweight 4.8V pack (ie 4 cells) and a DC-DC converter. Ahab assembled an AA 1800mAh pack with an integral converter and it works fine and gives more than adequate performance. He was driving a bullet cam and a video Tx. In my opinion you are far better off avoiding problems in the first place rather than trying to cure any symptoms. Therefore isolating one system from the other has to be the starting point. With regard to motor power leads before and after the controller: Keep them as short as possible, use high quality connectors and use the most substantial cable with the lowest resistance possible. I am sure that the electric flyers amongst us will be able to offer you further advice. Hope that helps GL
  13. No not yet, another thing for the 'To Do' (and the 'To Buy') list! I did put a cheap (~£15) fixed focus film camera on a trainer type model four or five years ago and was amazed at some of the results I got. Maybe I will post some of the shots on my site sometime.
  14. I have finished modifying my Mk2 PilotCam for my Sopwith Pup. I was having trouble with picture break-up and eratic camera movement which I finally traced to the minature toggle switch I'd used for the system power for the camera R/C and the video system. I already knew these toggle switches were useless for applications with vibration as a friend lost an aircraft a few years back due to one. Unfortunately I'd forgotten the lesson we had learnt the hard way. If you've got some don't put them anywhere near an IC powered aeroplane! You can see some photographs and details of the modified PilotCam here: http://uk.geocities.com/tulyar-AT-btinternet....m/PilotCam2.htm and my Biqaud receiver aerial, built from Cyber-Flyer's drawing, which works really well here: http://uk.geocities.com/tulyar-AT-btinternet.....com/BiQuad.htm and finally some stills from the first flight at sunset yesterday evening here: http://uk.geocities.com/tulyar-AT-btinternet.....com/Photos.htm Hope you like them ....
