Delta Twister Flying Machine Kit by Gakken [AF-1844]

The Delta Twister is a build-it-yourself lightweight flying machine that's perfect for both amateur flight enthusiasts and amateur makers. The Delta Twister flies either by a wound up rubber band or a small electric motor that propels its dual-plastic wings to flap rapidly through the air.

This kit requires two AAA batteries that aren't included but we sell them in the Adafruit store. No special tools are needed and there's no English manual so this one is a bit more challenging than the other Gakken kits. The pictures in the Japanese manual are fairly simple to follow, however, and the kit should only take a couple of hours to build. The Japanese Manual (with pictures) is available for download here.
