Its a remote control airplane Kit. called the flying lawnmower. there
is a small engine and prop on the front.
The FlyingThingZ Sky Cutter is one of the better known kits, designed
to take a 40 size glow engine and 4 channel radio gear with mixing
ability.
The kit comes in ARF form and can be completed in a weekend if you have
a basic knowledge of rc airplane (or mower...) assembly.
