I have also learned a lot from the hardcore R/C ATV (Amateur TV) guys at http://www.RC-CAM.com . It's worth it to read the archives at the forum, there's a lot of valuable info there. They are taking the 100ft range X-10 Cam and upgrading it dramatically with homebrewed antenna's and better cams. I think I would start with something a little better than that, no less than 100mw on the tx power, in the 2.4ghz range. But there's 1, 2 and 3 watt systems out there. That's just incredible, to fly a model out of sight and fly it only on the radio links. Just a few years ago it was only done by a handful but with the 2.4ghz stuff it's becoming much more popular. I started my project two years ago and have researched it all again recently and in just two years the number of websites devoted to the activity has skyrocketed. I think I've come across 15 sites that sell systems, and another 20 sites by the flyers themselves. So far I have $179 in my system. If I can get 15 db of gain on the receiver, I'll probably outperform the $300 systems. I bought my stuff at Supercircuits.com, the CMOS camera was $69 and the tx/rx set was $110. Now you can get a CCD camera for only $79 and all kinds of wireless link options. You want a CCD camera, don't bother with a CMOS camera the sharpness and color rendition just isn't there. It's possible to have stunning picture resolution with a CCD camera. -Tom
