The VP-12 is a two-seater airplane, designed for amateur flights, initial training, tourism, monitoring operations, entertainment flights, etc.
The main features of the VP-12 aircraft are a very high aerodynamic quality, which allows it to be used as a motorcycle glider in the CS-22 category, and the possibility of using an electric power plant on this aircraft. High aerodynamic quality significantly improves the safety of the flight in case of engine failure and allows to have high cruising speed, range and duration of the flight in comparison with similar aircraft.
Due to the high aerodynamic quality, the aircraft has a minimum fuel consumption, which leads to very low operating costs.

The aircraft has a scheme of a classic low-wing airplane with a tractor engine in the nose section of the fuselage, a T-shaped tail, is equipped with a tricycle landing gear with a steerable nose wheel.

One-piece wing of the aircraft is made of carbon, which increases reliability and allows to reduce the weight of the glider and the cost of production. There are ailerons, flaps, and interceptors on the wing.

The fuselage of the half monocoque construction is made of carbon and has power frames and ordinary frames, and skin in the form of a sandwich panel.

A non-retractable landing gear with a pedal-operated front foot simplifies steering on an airplane.

To save the crew in case of an unforeseen emergency, there is a rescue parachute system that saves the entire plane with the crew. The parachute throws out a special rocket, which allows you to open the dome very quickly and at low altitude.

The most important feature in this category of aircraft: if for some reason I lost my medical examination and did not pass a medical examination, I can still fly on motor gliders.

Motor gliders are a cross between airplanes and gliders. They offer the following advantages:
  • The ability to fly without a medical certificate. Since they are gliders, there is no provision for denial of this privilege in the event that a medical certificate has been previously denied, as in Light Sport Aircraft. Like any other glider (or airplane, for that matter), the pilot is expected to not fly if they believe they are not fit to fly –self-certification.
  • The ability to self-launch without a tow plane or winch.
  • The ability to fly during times when there is limited lift – early mornings, evenings – winter.
  • The ability to go places. These are well-designed traveling machines, capable of long-distance flights.
  • Since they have an electrical system, they are equipped with radios, GPS, and transponder/encoders, allowing flight within Class B airspace.
  • Unlike LSA aircraft, they are not restricted to altitudes of 10,000 feet.
  • With their long wings, they burn very little fuel – 2.5 to 5.5 gallons per hour, depending on the engine type. Of course, they burn NO fuel with the engine shut off! Rotax engines can be used with auto fuel. In fact they prefer it with a minimum 91 octane.
  • With their large wing area, these aircraft offer low stall speeds, fast climb, and near-STOL capabilities. They usually employ glider-like spoilers or airbrakes for direct lift control and steep descents. Once you fly an aircraft with spoilers, you’ll wonder why every airplane doesn’t have them.
  • The ability to fly a unique aircraft… an aircraft sure to turn heads where ever you go.
  • For a private pilot converting to gliders, a minimum of 10 solo flights are required to qualify to take the glider flight test. No written exam is required – just a flight test with a Designated Pilot Examiner – and it counts as a biennial flight review.

We do not have small taper ratio, but the fall characteristics do not deteriorate due to the application of aerodynamic and geometric wing twist, wing strake and slotted ailerons. The plane will be securely parachuted without the tendency to fall on the wing.
With regard to wing area and wing load, I will give some examples for comparison. VP12 has a wing area of 9.37 m², a maximum take-off weight of 482kg, a wing load of 51.44 kg/m².
H36 DIMONA has a wing area of -15.24 m², maximum take-off weight of 770kg, load per wing - 50.52 kg/m².
The advanced version of the H36 aircraft DA20 KATANA has a wing area of -11.61 m², maximum take-off weight of 800kg, load on the wing - 68.9 kg/m².
Therefore, such area and load is chosen by us not by accident, it is necessary to get high speed in the motor glider mode at transitions.
To illustrate the above, I can give you an example of a modern glider that uses water ballast of up to 200 kg of water to increase wing load and speed accordingly. Because whoever goes through first wins.
We also took care to reduce the drop speed at a small wing area (9.37 m² ), due to the application of a high degree of wing mechanization throughout the wing, as well as the use of a high-bearing wing profile. This allows to process the ascending flows at low speeds. And by removing mechanization, you get a significantly higher cruising speed.

The height and width of our cab is not more than that of the Virus SW 100, and we spent a lot of time on prototyping the cab so that it is not large but not as tight as possible.

The title of this thread is really confusing. Is this a homebuilt or a future Kitplane?

Fuselage seem as copy of Czech Zephyr, Faeta. Tail should be placed higher. Also Czech Lambada was plane of this kind.
Yeah, you’re right, it really is alike. You can find a lot of planes that it would be somewhat "alike". All the plane builders copy from the Wright brothers, and so do we.
In any case, in every aircraft category, the market is paramount. And anyone who starts the process of building an airplane does so with the secret hope of "conquering the hearts" of the buyer.
First of all, let’s take a look at the class of this aircraft (the motor glider) - it is a very resourceful, inexpensive, modern aircraft that can help both the newest and the most sophisticated pilots.

Alex, Wright brothers wasn't first who flew motorised plane - first was european Gustave Whitehead :)
Also word "inexpensive" shouldn't be said in junction with composite planes.

=the aerodynamic ( Cd) works=see todays glider fuselage form...(rear part have negative curveatur)
Henryk, I probably mean something different. Tail should be placed higher behind cockpit and not so steeply narrowed - it help lower aerodynamic wake - vortex. Second profit is that pilot can pull plane on higher AoA at take off and can do better flare at landing, without too high landing gear!
