July 2004 issue of RC Car Action. Page 42. "XXAP Design Inc. Metal Tech Racers". After I stopped drooling on the magazine, I went to find out more. The xxap site makes it sound more like they might be called "Pocket Racer XS" instead.
They seem to be about the size of ZipZap, metal body, digital-propo steering and speed control, can run up to 8 together, interchangible bodies, plastic racing bodies, Lithium batteries, 30 min to 1 hour runtime... Sounds like 3 different chassis will be available: Sportscar, racecar, suv
So far I've seen bodies for: a BMW, a VW (water) Beetle, an Audi TT, and a rumor of a Corvette.
The magazine gave the wrong URL, it's really:
http://www.xxap.com/
They seem to be pre-patent, so there really isn't anything else to go on. Don't seem to be for sale yet. No word I've seen on price.
The video clip on the site makes it look like they should be pretty quick. (Maybe on par with dual-cell mosfet?) The propo throttle and steering look smooth. And they've got reverse.
But it looks like these should be able to spank the pants off a ZZ-SE from a technical stand point!!! And probably spank any current micro rc on a very tight technical course!
