Wireless video does have it's place. I still have mine in the plane for when I'm at funflies or schools or places where people want to see video in real time. But the vast majority of what I have seen in this and other sites is simply recording flights. That doesn't require a live downlink. Although they don't post it on the net, I know a guy that belongs to an Ultralite club and they video each other like that quite a bit, but all they use is a camcorder strapped onto the plane or their helmets. Sometime this summer when it's nice a green there's a stretch of road I'm going to video from my Harley. It's all twisty and I'll strap my DV 4000 onto my helmet and give ya all a thrill
You'll wonder, just like the locals, just how I've managed to survive all these years............[X(]
