PitPit is a single-seat helicopter with a two-bladed rotor powered by a hybrid jet system. The required volume and air pressure is provided by a five-cylinder, four-stroke, 2.7 dm3 radial combustion engine. A centrifugal compressor drives the engine via an acceleration stage. Thanks to the mechanical supercharging, where the loss of power with altitude is limited, the helicopter achieves considerable range and, thanks to the reactive propulsion, exceptional climbability. The propulsion concept ensures high reliability with a minimum of mechanical parts. Low engine operating speeds in the range of 2 - 3,000 RPM together with an efficient exhaust system produce a pleasantly deep, low intensity engine soundtrack both near the ground and at altitude.

The machine has a very low centre of gravity, giving it exceptional stability on the ground but also in all flight modes.

The pressurization system has been designed with maximum use of CFD (Computer Fluid Design) to achieve the optimum combination of the required propellant compression ratio with minimum accompanying heating of the air conveyed through the rotor system to the multi-flow propulsion nozzles. In contrast to the solutions used on machines with "jetrotors" in the past, this results in a significantly lower temperature load on all components. The nozzles driving the rotor are multi-flow. The mode of operation of the cold/hot jet system and its thrust is determined by the digital control system according to the flight mode. The control electronics can be deactivated/activated at the pilot's option.

Due to the rotor drive principle, the gearbox and associated systems including lubrication are completely absent, and there is no need for a tail compensating rotor or other compensation system.

Because there is no torque transfer between the motor and rotor, the normal development of resonances is absent and vibration is minimized. Because of the lack of mechanical linkage between the airframe and rotor (except for the rotor bearings themselves), two common causes of accidents in conventional helicopters are completely eliminated. The first are failures of the tail rotor, its transmissions and associated gears, including failures of the associated oil system. The second category of completely eliminated accidents are sideways and forward rollovers of conventional helicopters when the helicopter is untethered from the ground, accompanied by subsequent rotor-to-ground collisions and complete destruction of the rotor and machine.

The momentless linkage between the fuselage and rotor allows the use of a practical three-wheeled landing gear, with a sprung front wheel, facilitating ground transport and handling relative to conventional skid landing gear, and range during autorotation. The larger diameter main wheels allow safe operation from unpaved surfaces.

Rotor control is by means of a simple cyclic control leading from the rotor directly above. Thus, there are no gears or rods in the rotor control system and there is no steering play.

The rotor blades are suspended with full freedom of movement in the vertical plane, i.e. in the "flapping" plane. The rotor head itself is connected to the carrier shaft via a full 3D gimbal. There is thus no possibility of fatal accidents from "locking" of the rotor cradle against the rotor shaft, i.e. a hazard inherent in the 2D cradle system design used almost without exception on conventional UL and light helicopters. The rotor can be folded for easy storage.

Conceptually, however, the PitPit is a minimalist technical device fulfilling everything a pilot needs in terms of safety. Behind the seat area there is a storage space for e.g. sleeping bag, tent and fishing rods and other cargo up to 10 kg.

PitPit is a minimalist representative of sport flying devices in the category of ultralight helicopters.
