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.

  1. I've only flown this 3.2 mp camera once. It's never been crashed or damaged in any way. It takes great photos. I just bought it to get me by till I got a higher res camera. It comes with all the cables, cd rom, manual and a 16mb sd card. It takes AA batteries that last quite a long time. I'm asking 100 dollars shipped. Paypal only will be accepted.
  2. A reverse coupler would be like your car having a + ground system. A normal SMA connector has the center wire as the signal and the threaded part is the ground or reflector. Avoid a reversed SMA antenna.
  3. Try this. Get a pole or some way to elevate your receiver and antenna. The higher the better. That way your controller antenna will never be in front of your video receiver antenna. Just get a longer RCA cable to run down the pole to your monitor. I used a piece of metal conduit with an "L" on top to strap my receiver onto. The end of the conduit that I stuck in the ground was slash cut to make it easier to work into the ground without having to be driven into it.
  4. I'm glad it's working so well for ya. I've got one on my 2.4 Ghz setup and it works equally as good.
  5. Are you using the GP patch that I sold you for the video? I was wondering how well it was working for you.
  6. I put a small plastic box around it a while back. Since I've found a digital camera that has continuous shooting I don't use it that much but a lot of people want to wear the helmet while I'm doing AP so it's still cool I did some AP for a fellow from work, on his home, and he wore the helmet and told me where to fly from for the best shots. That has become a selling point as it allows who I'm shooting for to have a hand in the final outcome. I've also found that since I'm recording from the digital camera, a perfect signal isn't that important because I don't fly from the camera anyway. M
  7. 410 lines resolution, color, and operates on 9-12 volts. Not sure of the brand although I think it's panasonic. Delivers a stunning picture. It's around 3/4 inches wide and 2 inches long. I've used it maybe half a dozen times but no longer have a need for it as I'm using my digital camera as the camera for my tx. I'm asking fifty dollars for it.
  8. Since you will be using a kite, which is basically a more or less stationary object, I'd look into a yagi antenna. A GP Patch antenna would be cheaper to build so you might want to start with that first. You can build a GP antenna for around ten bucks and they work beautifully
  9. That must have been it. I took the plane outdoors this morning and did a little more fine tuning and viola! The line went away completely and stays away when I transition from the CCD camera to the Nikon.
  10. Mine is the 1.5 watt version. You're right about the adjusment being near the input/output side. When I turned the screw clockwise I got the weird line even indoors, but when I turned it back counter clockwise the line went away. I'll have to fine tune it in the morning in the daylight. I might melt some wax over it to hold it in position once I get it just right. Thanx for your help, guys
  11. EUREKA!!!!!!! The small silver phillips head screw was it. I turned it one way and got a line across the screen. Then I turned it back the other way and the line went away completely. I figured I couldn't screw it up anymore than it was so I took a chance and I think I found the problem. Now I just have to wait till daylight and see if that's really it.
  12. Here are two photos. In the first photo is the tx. There are two flat tip screws at the top, which I am pretty sure are voltage related. Then, in that same section is a phillips screw in a small square at the bottom right of the section. Those are the only three adjustments I can find. In the second photo are two screws at the top. Since these are very near the voltage in and voltage out I'm pretty sure those are voltage related as well. Any ideas guys?
  13. on top of the board in the tx, there's a tiny silver phillips head looking screw. Could that be it? I don't see anything other than a screw next to the power jack on the tx. It's a straight slot screw on a tiny plastic square. I'm pretty certain that's for adjusting voltage and not anything else.
  14. It does the same in any frequency but in low light conditions that line appears to go away. In bright light I get the line whether I use my Nikon 3700 to view or my ccd camera. Indoors with the lights on no matter how bright I don't get a line. Only outdoors.
  15. I took the plane out of town a ways and I got an interesting result. The band has moved to the bottom of the picture in the monitor. In the shop I can put the whole mess on one table and get an absolutely clear picture. It only does it outdoors. I've wondered about light issues but this is the same setup I've been using since last fall, with no problems. So I'm guessing it has to be some sort of new rf that has moved into the area. Maybe something the govt has put up like they do to monitor phone switching equipment. I'm baffled. I'm almost to the point of just ordering a whole new video s
  16. The odd thing is that this only happens when the plane is outdoors. When I test it inside my metal shed there is no problem. It's only when the plane is outside that it's an issue. It has to be some sort of interference. Now I just have to find out what the interference is. I've tried all four freq's on both the tx and the rx with the same result.
  17. I completely disabled both phones and the cradle and I get the same dark band across the monitor. Oh well, at least I tried
  18. I've only tried this at my home so I don't know if this is the possible source, but we did get two new 2.4 ghz phones a while back. I tried unhooking the main cradle for the number 1 phone, but I never thought about taking the batteries out of both phones and I'm wondering if they send out a signal whether the phones are in use or not. I think that will be my next test. I'll take the batteries out of the phones so they are completely disabled and try that. I'll let you all know what I find.
  19. I'm running the power from a freshly charged 1800 ma 10cell pack. That's never been a problem before. I've been running this whole setup since last fall and this is a new occurance.
  20. If I use my wireless system to view my AP with my nikon or using the onboard CCD camera, I get this weird dark band across my TFT monitor on my helmet. It's like the image is darker in a line across the center. If I hook the monitor directly up to the vcr in my house the picture is perfect. Is it possible that my video rx or tx is malfunctioning or has some compatibility issue? If I use my nikon to take pics or record video there is no such line across the downloaded pics and videos. I'm kinda perplexed as to what the problem could be.
