The Sukhoi aerobatic aeroplanes of the Su-26/29/31 series demonstrate superior acceleration and rate-of-climb performance, excellent controllability, a high level of permissible g-loads, an all-round field of view from the cockpit, and unsurpassed structural integrity (destructive load 23 g), which makes it possible for the pilot, when coupled with a 35-degree seat back tilt, to repeatedly generate +12/-10 g loads, giving him a significant advantage in handling this relatively high-speed aircraft within a limited flying space. In case of emergencies, the pilot is in a position to escape from the aeroplane using the SKS-94M ejection system.
The Sukhoi aerobatic aircraft has emerged as a family of superior aerobatic aeroplanes, allowing pilots to use them for training and world class aerobatics competitions and exhibition shows. Since 1996, a majority of international contestants have been entering competitions with Sukhoi aeroplanes.

-----------------------------------------------------
In 1983, acting on the initiative of General Designer M.P. Simonov, a group of enthusiasts at Sukhoi Design Bureau under the guidance of V.P. Kondratyev started to develop a new aerobatic aeroplane under the manufacturer's designation S42. The development followed the performance requirements of Central Committee of the USSR DOSAAF [army, aviation and navy support NGO]. The development team also included MAI students: the joint project was supposed to provide hands-on experience for future design bureau members.
* The main features of the new aeroplane were: high power-to-weight ratio achieved through a rugged design, the weight of the airframe being kept down to a minimum;
* special aerodynamic symmetric-profile wing configuration to enable superior piloting performance;
* a robust airframe structure capable of sustaining +12/-10 G loads;
* extensive use of composite materials in the design;
* ergonomic cockpit configuration.
The design work involved revision of the existing strength standards for highly-manoeuvrable aerobatic sports aircraft to support a new level of pilot performance and to confirm, using unbiased monitoring systems, that the pilot can safely perform an entire range of aerial stunts under forward acceleration up to +12g. The design of the new plane incorporated the requests and comments of sports pilots from the USSR national team, as well as modern trends in the development of aerobatics. As a result, the design was based on new guidelines for developing a highly-manoeuvrable aerobatic aeroplane.
In May 1984, B.V. Rakitin was appointed head of the Sukhoi Design Bureau sports aeroplane project.
On 30th June 1984, the FRI airfield named after M.M. Gromov in the town of Zhukovsky saw class III test pilot Evgeny Frolov, a former member of the USSR's national aerobatics team, who later became a Hero of Russia, take off in the first prototype aeroplane, which was named the Su-26 (S42-1).
In the course of flight tests, which were completed within two weeks, the pilots of the USSR national team got a chance to practise handling the prototype aeroplanes. The Su-26's superior performance was demonstrated in the air, its high manoeuvrability and controllability being its strongest points. The aeroplane rolled at a speed of 1 revolution per second (over 6 rad/s). No other sports craft in the world showed such performance at that time. A high g-load was generated with a minor adjustment of the joystick. The pilot had an all-round field of view through the canopy.
The Su-26 was unveiled at the world championship in Hungary in August 1984. Pilot Yurgis Kairis took 24th place in the individual performance category. Despite the unimpressive result, participation in international competitions provided the experience required to redesign and fine-tune the aeroplane. The efforts focused on reducing weight.
To realise its high potential for manoeuvrability and controllability, it was necessary to lighten and strengthen the aeroplane sufficiently for it to sustain high g-loads, to extend its limits, and keep it all in a streamlined form. The problems were solved by introducing cutting-edge materials -- robust and light composite materials such as carbon fibre-reinforced plastics, organoplastics, and glassfibre reinforced plastics, as well as heavy-duty stainless steel, titanium and aluminium alloys. The Su-26 was used to try out a new design of wing and fins. In a short space of time, the design bureau produced documentation for the upgraded aeroplane, which was designated Su-26M.[...]

great pilot
if i could fly any plane, it would be the su-31
