This long, slender, cantilevered wings draws me in like a bees to honey. If it does the same for you, this is one sleek choice. Surprisingly, it won't cost an arm and leg. In fact, the kit KR-010 is base priced at $39,000 plus a shipping fee(2). Elf is quite complete for this price tag but you can bid it up into the $40,000s by adding an airframe parachute and com radio.
As Kris describes the single seater: "KR-01A Elf is a full composite single seat SLSA that operates like a motorglider. It uses Parabeam® vinyl-ester resins composite material resulting in an amazing empty weight of 264 pounds, to qualify for the German 120-KG Class."
"Elf was designed by Jerzy Krawcyk of Ekolot by utilizing the early work of Slovenian-American Alex Strojnikun," explained Kris. "Elf features removable cantilever wings, cockpit under bubble canopy with tricycle fixed landing gear. The power-plant is a two-stroke engine with aft-folding composite propeller blades and can be equipped with ballistic parachute."
The producer of Elf and the also-very-handsome Topaz plus another model named Junior comes from PPHU Ekolot, a Polish manufacturer based in the city of Krosno. Formed in 1995 by director Henryk Slowik, a successful Polish business man, the chief designer is Jerzy Krawczyk, an aeronautical engineer who graduated from Warsaw Polytechnics – Aircraft Design and has 35 years of experience in designing aircraft.
Headquartered in DeKalb, Illinois, Kris operates NIU Group doing business as Ekolot America,
the distributor and importer for Ekolot.

Welcome to the newest Special Light-Sport Aircraft …except that it isn’t so new(1). Indeed, we’ve seen the Ekolot Elf for a few years in this country. Here’s what I wrote on its introduction in 2017. I was immediately drawn to Elf for two reason: One, I love soaring flight, which represents one of the most enjoyable challenges I’ve found in flying. “Hooking” a thermal and riding it thousands of feet upwards with the engine off or idling is not only magical; it’s also a good skill development exercise. Two, Elf was initially promoted as a Part 103, which I believe is aviation’s most charming — and certainly least-regulated — segment. Low prices, no pilot license required, no N-numbers, no medical of any kind …well, no wonder Part 103 aircraft are selling so well the last few years. In Germany they have the “120-Kilogram Class,” meaning airplanes that weight no more than 264 pounds (very similar to the U.S.

While Elf is capable of speeds close to 80 mph, the factory lists cruise at 71.5 mph (62 knots) which is not much above the Part 103 speed limit of 63 mph — or, per regulation, 55 knots. The Polish producer intended Elf to fit in Europe's fairly new 120 kg class (120 kilograms is 264 pounds, not much above Part 103's 254 pounds, though trimming weight when an aircraft is already this light could prove challenging). Because the Elf at Sebring had a parachute system it could weigh 278 pounds but the speed problem remains.
As Ekolot has already achieved SLSA approval for their two seat Topaz, they should be experienced in proving compliance. Once Elf has earned a Special Airworthiness certificate, the aircraft can use its full speed potential and could add pounds while easily staying inside LSA parameters.
Controlling Elf is common with center-mounted joystick and dual rudder pedals. The nose wheel is steerable and features a hydraulic brake. Dual main gear use composite suspension; the gear width is rather narrow but while permitting regular ramp operations, keeps the gear closer to the fuselage adds to the general smoothness of the design. The only unusual control is a right-shoulder-mounted braking handle for the prop.
Ekolot's JK-01Elf uses a single cylinder engine with folding prop, which itself is sophisticated with a small disc brake to slow the prop allowing it to fold back on hinges. When restarting after soaring as long as you wish, the blades will swing out and forward as motion develops lift. The electric-starting Polini Motori Thor 200 two stroke one cylinder air cooled engine offers max power of 26 horsepower at 7000 rpm. Elf is sleek enough and light enough that 26 horsepower is sufficient, said Kris. On board fuel is about 4.5 gallons. Under high power that won't last too long but this slippery airplane is meant to be flown with engine off or at low power so that represents plenty of fuel.
