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

description
fuselage:
- 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
cockpit:
- 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
controls:
- 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
antenna:
- radio antenna in fin
wing:
- 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
finish
- 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.
