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. If you're thinking of going the Futaba radio with Spektrum module route, this looks like a pretty good deal, and it comes with the Spektrum module! http://www.rcuniverse.com/market/item.cfm?itemid=532020
  2. The 8103 has a Spektrum module inserted, so you can still use the AR9000 in that case. By far, though, the easiest solution has been to purchase a used Futaba 9C and a Spektrum module to fit it. Spektrum is selling the Futaba modules dirt cheap to try to get people using Spektrum equipment. After going that route I wouldn't even fool with the other techniques.
  3. That's exactly what I thought! Looks like I need to spend some more time on this forum. That's a great build! Tim
  4. OK, quick update: Using the TrackR2 with the DX7/JR 8103 trainer setup WORKS! At some point I'll try to update with more info.
  5. I purchased a Spektrum radio long before I had any idea I would ever need to use selective channel assignments on the trainer port. I'm sure that there are people just getting in to FPV that have made their purchasing decisions based on the JR/Spektrum limitation, though. Unfortunatly the market is probably small enough that they'll never realize that they're losing business because of a stupid self-imposed limitation in their software. That said...my TrackR2 is on its way right now. There should be no problems going from my DX7->TrackR2->8103 w/spektrum module.
  6. You could get a JR 6102 for just over $50 on e-bay. Maybe cheaper other places (RC groups classifieds?) http://cgi.ebay.com/BRAND-NEW-JR-6102-COMP...1QQcmdZViewItem IMHO that would be a cheap way to get head tracking working with Spektrum. Use the 6102 as a slave, DX7 as a master. I haven't tried it yet, but you may be able to get the DX7 to transmit more than 7 channels when doing this. I need to hook up my AR9000 and give that a try.
  7. ALMOST there I did buy the module. While I'm waiting for the TrackR2 to be available, I wound up buying something else that will make things even easier to set up. I found a used JR 8103 that takes modules. I got it for around $100 including a case and a decent NiMH/NiCad charger. Here's why it makes things easier: First, the Spektrum module plugs right in to it so I don't have to worry about how to power it. Second, using the TrackR2 I'll be able to go straight from the DX7 (slave) , to the TrackR2, then to the 8103 (Master) with the Spektrum module. I can still add external
  8. I was thinking ground loop reduction. Maybe that isn't a problem here. My shielding is the system ground currently. I think you're right, it would only be a problem if you had a separate shield that isn't acting as the system ground.
  9. The shielding in this case is just the ground wire. It's basically coax cable. I'm sure you could go one step further and use two conductor wire with a shield around that. In that case, you would want one side of the shield grounded, I think the camera side.
  10. I use shielded wire from a set of light weight audio/video cables I had sitting around.
  11. That's not how mine works. Unless they've changed something recently (which would be nice), all the Spektrum receivers except the 9 channel one only have throttle fail safe and all other channels hold their last position. The do go to the "bound" positions when you first power it up, but if you lose a signal they hold their last position.
  12. Since mine is mounted in basically the exact same spot... I don't really see any blind spots from having the TX on the wing tip. I'm using a 500mW 900MHz video setup. http://www.vimeo.com/414571
  13. Hey! You pretty much mounted the camera and TX right where I have mine mounted! I noticed you put a ferrite core on the video TX lines. I was considering doing that, but I was concerned that it could do strange things to the video signal. Any idea what sort of impedance mismatch it may create? I suppose if you don't see any ill effects in the video then it doesn't matter anyway!.
  14. Andrew123, I considered that option already, but a few things lead me to the configuration with the external module. Using a second radio means that there needs to be a second receiver on the plane and additional wiring to support it. Also, that receiver should at least be an AR7000 since I may do some "long range" flights and the smaller receivers won't have the range I'm looking for. AR6000's don't like the strong 900MHz video signals (trust me, I know this from experience!) and AR6100's only have a single (dipole) antenna and I've seen firsthand that their range isn't even close to
  15. I completely agree. I don't understand their thinking. The AR9000 DOES allow you to set failsafe positions for each channel. If they can do it on that one, you'd think they'd implement that on all the receivers.
  16. I'm trying to decide if I'm going to order a TrackR1 in the next week when it's in stock or if I should wait for the TrackR2 which is supposed to be the same price and will come out around the end of the month according to Anthony. The TrackR2 is supposed to have built in drift correction that helps it to self re-center (assuming you are looking forward most of the time anyway...) I'm going to order the Spektrum module soon. I was going to order it today from Toddsmodels for $250, but I'm thinking that I might wait since I really can't do much with it until I have the head tracker. I'm j
  17. Did you guys see that the Eagle Tree Seagull can send back RF link performance from the AR9000 RX? I wonder if they can integrate monitoring the AR9000 with their new OSD when it comes out...that would be very nice! http://www.eagletreesystems.com/Plane/plane.html
  18. Just an update: I'm going for it! I'm going to purchase the Spektrum module and the TrackR1 after Christmas. Let's hope that we'll know if it works by the end of January.
  19. Anthony (the TrackR1 maker) thinks this should work! http://www.rcgroups.com/forums/showpost.ph...9&postcount=415 I'm trying to talk my wife into letting me spend a big chunk of my bonus so I can get this stuff up and running. Unfortunately she isn't convinced yet.
  20. Kilrah, I just wanted to make sure you were thinking along the same lines we were about the reprocess/append mode. We aren't talking about using the radios internal RF module. We're talking about using an external module. The signal would never have to go back into the radio. We're assuming that the trainer port on the DX7 is outputting a PPM stream containing information for all 7 channels on the DX7. That signal would go to the TrackR1 (which I think currently supports reprocess mode according to some comments on RCGroups). Then, the signal would go from the TrackR1 to an EXTERNAL
  21. OK, I knew I saw it mentioned. If you search the TrackR1 thread on RC groups there are a lot of comments about "PPM Reprocess" mode. I've seen some specific comments about how it adds channels. http://www.rcgroups.com/forums/showthread....ess#post7036636 I really think this option can work. Unfortunately, my funds are probably a little short right now to make the purchase and try it out. My next purchase will be video goggles. I'd need to purchase the head tracker and Spektrum module at the same time to be able to justify either purchase. I don't think the wife will go for that .
  22. I could be wrong but I think the trainer port outputs all 7 channels. I've seen mentioned that the head trackers can append a PPM stream, so IF I'm thinking of this correctly: DX7 sends all 7 channels out through the trainer port TO the head tracker. The head tracker apends channels 8 and 9 to the PPM stream (or replaces channel 7 and adds channel 8 to the PPM stream). That signal then goes to the module which thinks it's getting a standard 8 or 9 channel PPM stream. The questions that need to be answered: -Does the DX7 output all 7 channels on the trainer port. there's a JR secti
  23. It isn't any cheaper than buying a whole new radio, but I had already thrown out an idea here that could/should work and would add the benefit of being able to change out your radio's TX antenna. Here's the text: This thread isn't getting as much traffic lately! I thought I'd try to revive it with a question. Since I'm using a Spektrum DX7 witch isn't apparently compatibile with the TrackR1, I was thinking of an alternative solution that would still allow me to keep my Spektrum and all the receivers I've accumulated and maybe even allow for better performance. Here's my idea, tell me
  24. I'm looking forward to some side by side comparision videos once you can do it. I know the KX131 has a lot of good characteristics for FPV, but the super-high sharpening effect they apply in that camera drives me nuts. (dark lines around light colored objects, white lines around dark objects) It gives the perception of showing more detail, but it really isn't. It's like cranking the sharpness setting on your TV all the way up. I was considering going with a KX151, but if this camera handles the lighting conditions better than it definitely will be my next camera. I like the 12V inp
  25. Yea, I verified that the switches aren't proportional. I didn't think they were! I didn't realize you were using the trim buttons. I've wondered if the DX7 can take proportional control through those channels. It probably doesn't, it's probably just expecting on or off from the switches. For the flap swith it's probably just expecting any of the three positions, off, position 1, and position 2. It would be great if it was prewired to handle a pot on those channels. Honestly, I have no idea where I saw a mod where someone rigged up a head tracker to work in place of a pot in their TX
