The metal transmission servos installed on the factory with ball head linkages provide precise control and contribute to the longevity of the model.

Flight performance and flight characteristics

Speed and gradient

The EFL01075 Sukhoi-Jet convinces with excellent flight performance. With its two 70mm impellers, the model reaches considerable speeds and impressive climbing performance. Users report maximum speeds up to 150 km/h in optimal conditions and an almost vertical climb over several hundred meters.

The gradient varies depending on the battery used. With a high-quality 6S 7000mAh LiPo battery, climbing flights from the stand over 200-300 meters are possible before the speed decreases noticeably. This allows impressive vertical flight maneuvers that come very close to the model.

Flight time

The flight time of the Sukhoi Twin-EDF jet depends significantly on the battery and flight style used. With a 6S 5000mAh battery, pilots can stay in the air for about 4-5 minutes with moderate flight style. When using a 6S 7000mAh battery, the flight time is extended to 6-7 minutes.

Experienced pilots who are familiar with energy management and are flying with reduced engine power predominantly in a glide flight report flight times up to 8-9 minutes. With aggressive flight style with frequent full-gas phases and vertical maneuvers, the flight time is correspondingly reduced to 3-4 minutes.

Flight characteristics

The Sukhoi jet from E-flite shows excellent flight characteristics despite its size and weight. Thanks to its aerodynamic design and precise control, the model is very stable and responsive at the same time.

The slow flight behavior is particularly impressive. The jet can be controlled to astonishingly low speeds before the flow breaks off. This significantly facilitates landing approaches and makes the model more accessible for pilots with less experience in the jet area.
