design/construction: Yann LeCun, summer 2003, modified summer 2004.
wingspan: 420mm, chord: 120mm (including 20mm full-span aileron on both wings).
mass: 150 grams with a 2-cell 340mAh Kokam LiPo battery.
motor/prop: MicRotex outrunner brushless motor with GWS 8043 prop (this replaced the original GWS LPS CN12-RLC 4.8V B / 5:1 gear ratio)
radio: GWS receiver with 3 Cirrus 4.4g servos (this replaced the original GWS Pico BB servos)
battery: 2-cell Kokam LiPo 340mAh (2S1P), or 750mAh Taisun LiPo.
materials: everything is made with 3mm Depron. The motor mount and the studs that links the leading edge of the two wings are balsa.
length of main fuse section: 400mm. distance between wings 95mm.

flight: The flight is unbelievable. The plane can climb vertically, do loops with a 1 meter radius, roll at unreal rates... Inertia doesn't seem to have any effect on this plane, and gravity barely does.

The old 4.8V GWS motorization had longevity problems (being over-volted by the 2-cell LiPo battery). The new MicRotex motor is absolutely marvelous. The plane is way over-powered with this: the thrust-to-weight ratio is about 2 to 1!
