UPDATE–November 2008: According to FPNA, an American company with a business relationship to A-20 producer Aeroprakt, the A-20 has been discontinued. Please contact FPNA for more information (contact info at end of article). Two summers ago Americans saw a new aircraft from a Ukrainian company called Aeroprakt as U.S. importer Spectrum Aircraft brought in the A-22 Valor. It would be only the first in a fleet of new microlights. Later another model from Aeroprakt appeared. In fact, the Vista series comprises 5 models, all variations on a basic theme that is nothing like the Valor. At present, the Ukraine enterprise has no less than nine models including the Valor, Vista, Cruiser, V-STOL, V-SS, Vulcan, Vulcan-SS, Victor single engine, Victor twin, and Viking. Four of this series are twin-engine aircraft, none are alike, and one is a 4-seater. By any measurement, this is quite an accomplishment from a company less than 10 years old and rising from the ashes of the failed Communist empire.

Notes: | 2The Vista is also available with the 66-hp Rotax 582 engine but since Aeroprakt then supplies the shorter "SS" wing, a 582-powered 2Vista may exceed speed parameters of the training exemption to Part 103 unless carefully matched with the correct, speed-limiting prop. No specifications are presented for the 582 models; see Spectrum Aircraft for more details. |
Standard Features | Airframe kit supplied with fuselage, wheels and disc brakes, wheel pants, full-span flaperons, vertical stabilizer, elevator, and rudder completely assembled with factory jigs. Landing gear, engine mount, windshield, and controls are all assembled and preinstalled. Basic airframe kit does not include engine, prop, instruments, electric, or fuel systems (see "options"), in-flight trim. |
Options | A quick-build kit is supplied ready for fabric covering and painting. Factory covering and painting are also available. 80-hp Rotax 912 or 503 (see specifications above), ASI, altimeter, VSI, digital EIS, electrical components, electric starting, hardtop canopy. |
Construction | Aluminum airframe, fiberglass fairing, dope-and-fabric wing coverings. Made in the Ukraine. Distributed in America by U.S.-based Spectrum Aircraft. |
Design
Cosmetic appearance, structural integrity, achievement of design goals, effectiveness of aerodynamics, ergonomics.
Pros - All new design series, created by a club formed of Antonov (big airplanes) aeronautical engineers. This team has created numerous designs. Differs in substantial ways from U.S. ultralights, but flies well at ultralight speeds and heights and can qualify for the training exemption to FAR Part 103 with a Rotax 503. Looks somewhat sailplane-like and flies with sailplane-like efficiency.
Cons - Aeroprakt is a new company and even with excellent flight characteristics, resale may take time. U.S. importer Spectrum Aircraft run by industry veteran John Hunter still must prove its longevity. No info gathered on testing, though no faults found in this evaluation. Most models from Aeroprakt cannot qualify as ultralight under present U.S. rules; therefore licensing and N-numbers are required.
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 - Very complete machine with dual controls at both positions (but not brakes). Flap controls in both seats; fluid, easily interpreted operation. Fueling is from outside the cabin under the right wing. Trim at base of joystick, reasonably reached for most pilots. Electric start on test plane.
Cons - Brakes are non-differential, although steering effectiveness showed no problems. Engine under cowl looks good but takes more effort for maintenance. Trim lever slipped a bit during evaluation; friction fittings require periodic attention.
Cockpit/Cabin
Instrumentation; Ergonomics of controls; Creature comforts; (items covered may be optional).
Pros - Roomy cockpit for most large Americans. Full dual controls including flaps make Vista good trainer. Well padded seats and 4-point seat belts are appreciated by most pilots. Panel is easily observed without limiting visibility too much. Easy reach to all controls. Throttle hand has a couple adequate rests. Windscreen-only option would be delicious in warm climates; swaps with full canopy in one minute.
Cons - My significant gripe in hot Florida was the full enclosure with insufficient air inlet; it's a greenhouse. Panel space is rather small, unless you use space-saving instruments like the EIS as installed in test aircraft. Seats not easily adjusted. Entry is okay, but requires some technique; did not try entry to rear seat. No luggage area if flown dual.
Ground Handling
Taxi visibility; Steering; Turn radius; Shock absorption; Stance/Stability; Braking.
Pros - Stable taxi steering even without differential braking. Superb visibility for traffic checking prior to launch. Brakes proved quite effective, certainly adequate for airport taxi operations. Slab gear felt like a good combination of absorption and strength.
Cons - Managing a propped-open canopy to ventilate the cockpit (with one hand), throttle and brake (with other hand) gets busy; a means to support the canopy would be more appreciated. Tail clearance looks rather limited for rough, off-field landings (though horizontal stabilizer is well clear).
Takeoff/Landing
Qualities; Efficiency; Ease; Comparative values.
Pros - The Vista Cruiser can slip dramatically, helping approach to small or emergency fields. Slab landing gear looks very strong and felt very secure; good in training situations. Takeoff roll and ground roll can be very short once you're experienced with the Vista. Huge visibility during takeoffs or landings. Flaperons work well to control glide path. Slips are highly effective permitting steep appro
Cons - Low tail clearance indicates the aft boom could be jeopardized in an emergency landing situation. It's hardly a negative (as reach is a good thing should you lose your engine) but the Vista Cruiser required slips for me to land short, so substantial is its glide.
Control
Quality and quantity for: Coordination; Authority; Pressures; Response; and Coupling.
Pros - Importer John Hunter focuses on flight characteristics as do I, so my saying it handles superbly shouldn't surprise anyone. The Vista Cruiser was delightful in every way, fast or slow. Light touch controls without skipperiness. Flaps and trim harmonize well. Little adverse yaw. Mass-balanced ailerons. Dutch rolls went well to steep angles. Very precise turns to heading.
Cons - Flap handle can slam shut if you don't keep your hand on it. Controls become understandably less responsive if the flaperons are fully deployed. No other negatives.
Performance
Climb; Glide; Sink; Cruise/stall/max speeds; Endurance; Range; Maneuverability.
Pros - Spectacular 1,700-fpm climb with 100-hp Rotax 912S. Huge speed range, running comfortably (low over fields, even) at under 40 mph, yet speeding to much higher speeds. Flaps-down, low-field flying was very pleasurable in the genuine ultralight way. Regional cross-country trips should be very reasonable. Efficient flying means less fuel consumed.
Cons - Speeds will have to be restricted if used under Part 103 training exemption. Long glide requires some effort to make steep emergency landing approaches.
Stability
Stall recovery and characteristics; Dampening; Spiral stability; Adverse yaw qualities.
Pros - Stalls under full power never broke. Power-off stalls broke but not dramatically. Surprisingly little adverse yaw. Accelerated stalls with liberal power never broke and did not fall to the inside wing. Steep turns for 720° carved well and held easily even without excessive power; another way to demonstrate the wing's efficiency.
Cons - Longitudinal stability checks were neutral, not worsening, but not quickly going level. Steep power-off stalls wandered laterally at incipient stall suggesting a wing drop though none happened. Throttle pushes nose downward if applied quickly.
Overall
Addresses the questions: "Will a buyer get what he/she expects to buy, and did the designer/builder achieve the chosen goal?"
Pros - The 100-hp Rotax Vista Cruiser is a versatile and thoroughly enjoyable aircraft. I feel confident in believing the 50-hp Rotax 503-powered model will be equally as excellent (but, of course, with a lesser climb rate and top speed). In virtually every flight characteristic, I found the Vista Cruiser shines and its performance is even better. If you don't mind being an early adopter, the Vista is a good choice, if you have the pocketbook.
Cons - Main downside is price; lower prices may be expected. Americans are spoiled by a higher state of finish; fortunately, Vista Cruiser functionality is superb. The 912S engine is powerful and quiet but comes at a considerable price premium over the 503 version ($8,000 more).
