The EB28 has since been replaced by the EB28edition. The EB28 can be retrofitted to the EB28edition.
Two-seater EB28
Powerful, comfortable, capable of self-launching.
The EB28 stands for innovation and maximum flexibility in open class gliding.
With its impressive wingspan of 28 metres and many practical details, it offers excellent flight performance and an exceptionally spacious cockpit area – even for tall pilots.
The carbon and Kevlar composite construction guarantees low weight and a robust design.
Equipped with a retractable engine with Solo Motor 2625 02, the EB28 enables independently planned cross-country flights and competitions at the highest level.
The aircraft combines comfort with state-of-the-art technology and can also be retrofitted to the EB28 edition. For pilots who want to reach new heights together.

Construction description EB28 two-seater
Fuselage
- The spacious cockpit offers comfortable room even for tall pilots.
- To ensure optimum passive safety, the seat pans are made from carbon and Kevlar fibres.
- The sprung landing gear is retractable and equipped with a hydraulic disc brake that is actuated when the airbrakes are deployed.
- The cockpit ventilation is supplied via an air intake in the nose of the fuselage.
- The fuselage is equipped with a tail water tank to compensate for the centre-of-gravity shift caused by wing water ballast.
Landing gear and brake
- Landing gear electrically retractable and extendable
- Sprung landing gear
- Hydraulic disc brake
- Tailwheel
Powerplant
- Solo engine 2625 02
- Water cooling
- Dual ignition
- Electric starter
- The engine monitoring instrument is installed in the instrument panel.
- For improved deployment and retraction as well as starting of the powerplant, batteries with a final charging voltage of 16.8 V are installed.
- Toothed belt (62 mm wide) with 1:3 reduction
- Standard with Binder BM-G1-160-R-120-1 composite propeller
Extras
- PU paint for improved temperature resistance and reduced cracking of the paintwork
- Electrically retractable landing gear
- Built-in refuelling pump for filling the fuselage tank
- Bracket for a 4 l oxygen bottle
- Leather interior (seat cushions and pocket set)
- Tinted canopy
- The transponder antenna for the Mode S unit can be installed in the fin, eliminating any aerodynamic interference.
- Wing extensions with winglets for 25.3 m wingspan
Cockpit
The cockpit is fitted with removable visible-carbon shell seats with integrated parachute pans. The one-piece plexiglass canopy provides the pilots with excellent visibility from the cockpit. The canopy is equipped with two sliding windows. The anti-mist ventilation for the canopy and one separate, individually adjustable air outlet for the pilot and co-pilot in the right cockpit sidewall are standard.
Equipment
- An electrically adjustable trim, operated by a switch on the front control stick, is installed as standard.
- The front rudder pedals are adjustable in flight.
- The aircraft is equipped with a TOST safety tow release for aerotow.
- The rod antenna for good radio reception is installed in the fin.
- For improved ground handling, the wing extensions are fitted with wheels.
- Fuel is carried in fuel bags with a capacity of 18 litres each in the inner wings, plus the fuselage fuel tank with a capacity of 19.5 litres.
T-tail
- Damped tailplane
- Tailplane in CFRP sandwich construction
- Fin made from glass fibre for reception of the integrated radio and transponder antennas
Wing
- The six-part wing with laminar profile and boundary-layer control on the underside is built using high-modulus fibre.
- The wingspan can be varied between 25.3 m and 28.3 m by using wing extensions of different lengths. Fuel bags with a capacity of 18 litres each are installed in the inner wings.
- The flaps and ailerons are also manufactured in CFRP construction using high-modulus fibre and are therefore particularly light and stiff.
- The CFRP airbrakes in the inner wing are fitted with spring-loaded covers on the upper wing surface.
- The water tanks in the outer wings each have a capacity of 50 litres. The carbon-fibre control rods in the wing are sealed with bellows.
Weight saving
Significant weight is saved by vacuum-removing excess resin during manufacture of the shells (fuselage, wings and tailplane). For example, the fuselage shells alone achieve a weight reduction of around 10 kg. A further 5 kg of weight saving is made possible by installing lithium-manganese batteries in the fuselage.
