The racing-two-seater EB29DR

EB29DR double-seater EB29D with performance-optimized R-wing

- completly new design of wing geometry to the edition wing
- lower wing aerea for higher wing load
- new wing profile with lower hight
- outlow over the intire span

The newly developed profile allows good performace in high-speed range and good circling properties at high wing loads. High modulus fiber in the complete wing shell produces a very high stiffness, wich is characteristic in fast flight.

But this is not the end of the development. Further model maintenance and performabnce optimization of recent years:
- the tailwheel is now electrically retractable and in addition steerable
      for better  ground handling
- the rudder actuation levers are now integrated into the fuselage and thereby
      the scoops at the tail fin and the rudder are no longer needed
- profile change of the nose at the fin
and last but not least
- the HLW2020 - an entire new elevator with a new airfoil and reduced area

  • body shell made of fibre reinforced plastic (CFK and aramide)
  • cockpit suitable for pilots up to 190 cm in the front seat and little less in the rear seat
  • forward swinging canopy including one sliding window with integrated ventilation scoop
  • instrument panel moves upward with the canopy
  • TOST-safety release couplings (for aero tow or winch tow)
  • total pressure probe in tip of the fuselage nosecone
  • adapter in the fin to fit TEK probe
  • static pressure probes (for air speed indicator and altimeter) on both sides of the tail boom


  • removeable bucket seats with parachute mould in the front seat
  • safety belts
  • seat cushions
  • 2 side Pockets (rear seat)
  • ram air entrance in the nosecone of the fuselage for ventilation and defogging of the canopy
  • seperately controllable ventilation for both seats on right side of the cockpit


  • rudder control pedals on linear rails (adjustable before flight)
  • control rods made of CFK
  • electrically adjustable trim with operating switches on both control sticks
  • automatic elevator connection

landing gear and brake:

  • rubber suspended, electrically operated retractable landing gear
  • hydraulic disk brake
  • tail wheel

power plant:

  • power plant retractable into the fuselage
  • solo engine 2625/2
  • tooth belt driven reduction gear (1:3)  
  • water cooling
  • double ignition
  • electrical starter
  • LiMg-batteries with 16,8 V max charching voltage for improved extension and retraction as well as starting of the engine
  • engine control instrument fitted to the instrument panel
  • Propeller Binder BM-G1-160-R-120-1

fuel tank:

  • fuselage tank ~20 ltr


  • radio antenna in fin


  • 6-part wing with boundry layer control on the lower wing surface
  • built using high modulous (HM) carbon fibre
  • aileron and flap gaps covered with Mylartape
  • double panel air brakes on the upper wing surface

water ballast:

  • water ballast bags in the outer wings ca. 35 ltr capacity each
  • water ballast tank in the fin to allow for compensation of CG-movement using water ballast in the wings


  • white two component plyester coat or PU-coat


To minimize the structural weight the main parts of wing and fuselage are built using the vacuum suction method. This allows the utmost possible spread in wing loading.
