2000 is a sleek delta-wing jet fighter built by Dassault Aviation,
and used by the French Air Force since the early 1980's. The real
plane has a 9.13 meter wingspan, for 9,500 Kg take-off weight (in fighter
configuration), and a maximum speed of Mach 2.35 (2,500 Km/h).
Like most Dassault airplane, this one is very sleek and nice
looking. Rumor has it that Marcel
Dassault was fond of saying that an aiplane could not fly
well unless it was beautiful.
- design/construction: Yann and Erwan LeCun, July 2006.
- wingspan: 66 cm.
- length: 99 cm.
- mass: 490 grams (including battery).
- motor: GWS EDF-65 ducted fan with Feigao 10A motor.
- battery: 3-cell 1800mAh Apache Lithium-Polymer.
- radio: GWS receiver with 3 GWS Pico servos.
- wings: flat 6mm Depron sheet, reinforced with a 4mm
diameter carbon tube near the control surfaces.
- fuselage: the nose is carved in a block of yellow
(urethane) foam. The rest of the fuselage is a 3mm depron
sheet bent into shape (with the help of a heat gun).

in Le Bourget, near Paris (click on the photo for more pictures taken
at the museum).
The wing is a single sheet of 6mm Depron that goes all the way to the
front of the turbines. Two flanks make of 6mm Depron are glued to the
top of the wing to rigidify it, and to mark the location where the top
section of the fuselage meets the wing.
The battery compartment was carved out of the foam nose section with a
piece of piano wire that was bolted onto a pistol-style soldering iron
(replacing the regular tip). The piano wire gets hot enough to carve
The top of the fuselage is a single sheet of 3mm depron which was bent
into shape beforehand (with the help of a heat gun), and subsequently
glued to the wing (and to the flanks), and to the nose section.
The EDF nozzle section is cut from a plastic bottle of sparkling
water (1 liter Badoit
water). The plastic of those bottles is rather thick (to hold the
pressure), and the design of the bottle has the perfect tapered shape
to hold a ducted fan (see picture). The ducted fan is held in the
bottle section with double-sided tape. The bottle section is bolted on
to two long pieces of plywood. The pieces of plywood are glued to
the inner surface of the flanks of the fuselage (the 6mm Depron
flanks mentioned above).
flight: This plane flies very well. The flight is rather gentle,
due to the rather low wing loading, and the rather small
motor. Nevertheless, the maximum climbing angle is quite steep.
The only problem is that the motor gets very hot when the plane is
flown at full throttle for long periods. Hence, I will replace the
motor by a more potent one.
The fun thing about delta wing planes like this one is the incredible
rolling rate. There are a couple fast and slow rolls in one of the
