Wow, that's what discretionary income was made for! Remarkably cheap, too. Um, I'm going to buy one (at Target), I'll let you guys know how it is when I get it.
Says 2-6 weeks though. Damn. I'll let you guys know, hehe.
Note that it requires a separate "LiPo" (Lithium Polymer) Battery. I'm not sure which model yet but they seem to run about $50 in themselves. So the actual cost is about $120. Still, if it does what's in that video, well worth it. It says ages 5 and up so I'm worried this may be a cut down, crappy version. The original design appears to have been productized and is now being sold through Target but that doesn't mean it's anywhere near as good. We'll see... Meanwhile the adventurous can build their own with the help of this info: http://www.aeromodelisme-rc.net/hydrofoam.htm
or buy on eBay
(note that there are apparently a lot of fakes around so be careful, or just be patient and see how mine works out
). Or if you are willing to pay a bit extra, there's http://www.trendtimes.com/recohy.html
($250, about twice the apparent cost of the Target one when you include the battery cost).
