4xTURBINE - 1:12 SCALE - CHALLENGING - REQUIRES DUAL-RATES/EXPO CONTROL MODESSCALE FLIGHT - HIGH SPEED PASSES - ENERGY MANAGEMENT
Model data:
Wingspan: 4.00 m (13.12 feet)
Weight: No-fuel: 286 lbs / 129.8 Kg
Fuel: ~24 Liter / 42.3 lbs
Engine: 4 x JetCat P300 Pro turbines (67.4 lbs / 30.6 kg thrust per engine)
Fuel consumption: 784g/min (approx. 980ml/min) / 15.5 gal/h (full power, per engine).
Performance/Limitations: Maximum demonstrated speed: approximately 200 knots / 230 mph / 370 km/h. Vne: 220 knots / 253 mph / 407 km/h. Note: the Concorde's exceptionally sleek airframe and very low frontal cross-section generate remarkable speed potential. At low angles of attack, the aircraft gathers speed rapidly and demands constant anticipation. At low speeds or higher angles of attack, drag increases dramatically and airspeed can decay very quickly. Full-throttle high-speed flybys are possible and visually spectacular, but must be flown with great precision and anticipation. Avoid abrupt pull-ups following a high-speed pass, as the resulting aerodynamic loads can rapidly exceed the airframe's structural limits. At speed and low altitude, this aircraft carries enormous kinetic energy and demands calm and planned inputs.

Pilot Notes:
General: The aircraft is a huge and heavy model, and its sheer size works against the instincts of pilots with limited or no experience in flying large models. Judging actual speed over the ground is difficult and requires gaining specific experience with this model. This becomes most critical on final, as the aircraft may appear to be at an appropriate approach speed, while its actual speed and remaining energy may be significantly higher than expected. Do not let this catch you off guard. For this reason, it is highly recommended to dedicate your initial flights to practicing finals and go-arounds without touchdown. Build the visual references before committing to a full landing.
Controls: Dual rates and/or expo are recommended at high-speed passes. The aircraft's wide flight envelope, ranging from relatively slow approach speeds to extremely high-speed flight requires attention. Inflight pitch trim (trim sliders in your RC transmitter) may be required for high-speed passes. Switch Dual rates/Expo off and set the trim sliders to zero for takeoff and landing, where full control authority and maximum responsiveness are required.
Energy Management: The aircraft's sleek, low-drag airframe gathers speed rapidly when flown at low angles of attack. At higher angles of attack, however, induced drag increases dramatically and airspeed can decay very quickly. This characteristic must be anticipated throughout the flight. During high-speed passes, avoid abrupt pull-ups or aggressive pitch inputs; allow sufficient distance to convert speed into altitude gradually and remain within structural limits. On approach, use angle of attack and power to control the energy state. Avoid excessive corrections close to the ground, as large changes in pitch can produce rapid changes in drag, sink rate and airspeed.
