The Pilot View FPV 2400 is a (wireless) camera system that can strap on any R/C plane and stream images to the pilot, who wears video goggles below. Range is about 1 kilometer over the 2.4Ghz spectrum, and the video quality from such systems really isn't so bad (hit the jump for an example clip). At $550, it's a commitment, and seemingly a tad risky to strap onto an even more expensive, properly-weighted R/C plane.
Kaiser want camera for first-person on the little moving things. I'd so eat this up for an RC race car, and when I've finally grown tired of first-person view from my toys, I'll send a home-made SCUD missile to my neighbor's window, and I can watch the eerie gawk of terror.
