The expression “seeing stars” is a good thing, if it means flying a delightful aircraft on a lovely day. After sampling the Sportstar in ’02 (see “Sportstar Pilot’s Report”, December ’02 Ultralight Flying!), I looked forward to a flight in its predecessor, the EV-97 Eurostar. You could say I had stars in my eyes. A blue Florida sky was dappled with miniature cumulus clouds, winds were mild, and the fuel tanks were full in a pretty blue-and-white Eurostar. I was ready. On a beautiful Saturday, April 17, I flew the Evektor Eurostar with Nick Motlagh (pronounced “MOTE log”) – a sharp young aviator about to embark on a career in the air. He has been accepted to compete for fighter jet training in the Air Force after graduating from Embry Riddle Aeronautical University in Daytona Beach, Florida. Motlagh had flown the Eurostar (N30167) over to South Lakeland Airpark to allow a flight review.

Design
Cosmetic appearance, structural integrity, achievement of design goals, effectiveness of aerodynamics, ergonomics.
Pros - With nearly 400 flying over 8 years the Eurostar is available in kit form as 51%, or, soon, as an ELSA. All-metal construction will draw general aviation pilots and anyone interested in longevity. Lighter and simpler than the Sportstar model. Czech producer Evektor has long history and experienced workers.
Cons - Even in kit form (more than 300-hour build time) the Eurostar is priced much higher than ultralights Americans have been buying. Full enclosure won't appeal to all ultralight buyers. Not well known in USA yet (though design should do well based on early feedback). Not everyone wants a low wing design.
Systems
Subsystems available to pilot such as: Flaps; Fuel sources; Electric start; In-air restart; Brakes; Engine controls; Navigations; Radio; (items covered may be optional).
Pros - Test Eurostar was well equipped with flaps, trim, and electric start. Easily reached access for engine repairs (delayed slightly for cowl removal). Storage pockets for both seats. Digifly instrument display offered much information in compact form (optional item). Four-point pilot restraints are standard.
Cons - Systems and features add to the price; even as a kit, the Eurostar isn't cheap. You have to pay for its features. More systems also mean longer build time for kits. Getting to engine for inspection/maintenance requires undoing nine Dzus clips. Trim is very responsive; move it slowly at first.
Cockpit/Cabin
Instrumentation; Ergonomics of controls; Creature comforts; (items covered may be optional).
Pros - Bubble canopy makes for superb visibility. Single latch secures cockpit. Entry/exit are straightforward; you can place your weight anywhere when climbing in from the wing. Gas pistons restrain large canopy. Instruction use served by dual controls including toe brakes for both seats.
Cons - Convenient as the single closure is, some pilots might prefer more secure latching (though a forward-opening canopy will not open in flight). Standard width canopy is not particularly wide, though an optional-cost cabin width is available at ordering.
Ground Handling
Taxi visibility; Steering; Turn radius; Shock absorption; Stance/Stability; Braking.
Pros - The Eurostar's ground handling is excellent; the plane can make a circle within its own 25-foot wingspan. Large, full bubble canopy makes for excellent visibility. Hydraulic differential brakes installed for both seats of this Eurostar; slows airplane reasonably well on landings.
Cons - On a hot day in Florida, the Eurostar's clear canopy was quite warm and a forward tilting canopy isn't good for generating some airflow during taxi. Low-wing design can mean some taxi obstacles may be obscured from view. Right side brakes are optional.
Takeoff/Landing
Qualities; Efficiency; Ease; Comparative values.
Pros - The Eurostar accelerated quickly with 100 hp. Takeoff roll was very short; landing roll also short, so short-field operations are possible. Climb was strong at nearly 1,000 fpm even in warm conditions. Excellent aileron authority for crosswind conditions. Flaps quite effective.
Cons - Takeoff roll may seem long to many ultralight pilots (though general aviation pilots will find it short). Split flaps don't add lift like Fowler flaps can. If you prefer high wings, the Eurostar's smooth landings may seem more challenging. No other negatives.
Control
Quality and quantity for: Coordination; Authority; Pressures; Response; and Coupling.
Pros - What's not to like? Comfortable control positions. Handling qualities are very good; most pilots will like controls. Harmony also very good. Precision turns to headings were simple. Adverse yaw is low. Good roll-in/roll-out response. Pitch dampened for ease of operation on longer, cross-country flights.
Cons - Unlike many ultralights, you'll need to use trim, and the lever is quite sensitive. Slow-speed handling softens notably near stall and this may feel different for pilots familiar with ultralights. On the whole, though, Eurostar handling is hard to fault.
Performance
Climb; Glide; Sink; Cruise/stall/max speeds; Endurance; Range; Maneuverability.
Pros - Climb is close to 1,000 fpm even on warm, humid days (though the lighter Eurostar benefits more than the Sportstar). The Eurostar cruises at 120 mph. Even with a Rotax 912S engine, endurance is over 4 hours. The Eurostar may often be used for longer flights, offers good comfort for two occupants.
Cons - Slow flight is not in the realm of genuine "ultralights" (though perfectly competitive with other LSA candidates). The Eurostar's smaller wings (two feet less span) than the Sportstar may offer a better cross-country ride, though I only flew for a little over an hour.
Stability
Stall recovery and characteristics; Dampening; Spiral stability; Adverse yaw qualities.
Pros - All stalls went very well, with no surprises whether power-off, power-on, or accelerated; nose fell through but not sharply. Turning stalls tended to level wings, either direction. Longitudinal stability was excellent, returning to level flight quickly. Changing power brought expected response (i.e., nose up on power-up).
Cons - Hershey bar wing design without washout or taper combines with low dihedral to keep roll-in/roll-out light, but exhibits some overbanking tendency in very steep turns. Power-on stalls produce a very high deck angle. No parachute installed in test aircraft, though company has engineering to install one.
Overall
Addresses the questions: "Will a buyer get what he/she expects to buy, and did the designer/builder achieve the chosen goal?"
Pros - Test aircraft was well equipped with instruments. Conventional design shape will encourage conventional pilots. A number of pilots I know really loved this design, especially its handling.
Cons - Much equipment in the test Eurostar is optional and price is already toward the high end. Relatively thin leading edge metal could see hangar rash. Interior finish is basic. Little U.S. market presence at this time.
