Evektor EPOS electric powered light sport aircraft

At Aero in Friedrichshafen Germany we had an opportunity to take a look at the Evektor SportStar EPOS and talk to Martin Dvorsky of MGM Compro. MGM Compro supplies the electric components for the electric powered EPOS. MGM Compro is located near the Evektor factory and has been manufacturing and supplying electrical components for a number of electric powered ground vehicles.

MGM Compro produces the controller, electric motor, batteries and battery and motor related software needed for the EPOS to fly. The controller is capable of producing 60 watts of power for an unlimited amount of time with a 99% efficiency rate, and generates little heat while it works. The 80 HP electric motor is also equipped with cooling fins. The batteries are located on each side of the aircraft, to the right and left of the motor and motor mount.

The batteries were designed specifically for this application and required a special computer program to manage them. This means that the batteries can be recharged for thousands of cycles. With the standard battery pack the EPOS fly under constant power for about 1 hour and can be recharged in as little as 15 minutes with a special charger. With a standard charger the time is 1 hour. This means that it costs in Europe about $5.00 U.S. dollars to fly per hour! When you compare that to an 80 HP Rotax engine using approximately 4 gallons per hour at $15.00 per gallon for avgas in Europe - that is a considerable saving on fuel!

According to Martin the Evektor EPOS on display was just to show what could be possible in the future - but "more than 10 people have come up wanting to buy an EPOS at the show!"

March 28th, 2013 – The Electric powered aircraft SportStar EPOS made its first flight from the Kunovice airport in Czech Republic today. The aircraft was piloted by Evektor's factory pilot Radek Surý. After taxiing tests at 8:25 am, the aircraft took off for its first test flight. After a short, approximately ten-minute flight, it landed successfully and a second flight followed immediately afterwards. The total time when the aircraft was powered by an electric motor reached about 30 minutes.

The SportStar EPOS (Electric POwered Small Aircraft) is a derivative of SporStar RTC and represents the concept of two-seater sport aircraft of the near future. The experimental operation of the SportStar EPOS was made possible due to close cooperation between Evektor company and the Czech Light Aircraft Association.

SporStar EPOS was aerdynamically optimized and is equipped with new trapezoidal wing of extended span. Aircraft is powered by 50 kW electric motor. Installed power unit represents the pinnacle of performance series of drives, which are also suitable for gliders, motorized rogallos or powered paragliding.

During the following flight tests, function of the power unit and its effect on flight and operational characteristics of the airplane will be examined. The objective is to develop an aircraft which can be used both by private customers, as well as flight schools as a suitable aircraft for initial pilot training.

The protoype SportStar EPOS was manufactured by Evektor-Aerotechnik company, one of the world largest manufacturers of the advanced light sport as well as training aircraft. Evektor-Aerotechnik sells its aircraft to 40 in countries all aroud the world.

The first SportStar EPOS presentation to the public took place at the Europe's largest aviation exhibition Aero Friedrichshafen in Germany.

The project of the aircraft SportStar EPOS is realized with the financial support of the Technology Agency of the Czech Republic under the guidance of the company Evektor and in collaboration with other Czech companies: Rotex electric - manufacturer of the electric motor RE X90-7, Aerospace Research and Test Establishment - manufacturer of the propeller, MGM compro - manufacturer of the motor control unit and Faculty of Information Technology of Brno University of Technology - supplier of the display unit for motor parameters.
