Want to fly RES (F3L, F5L) with ailerons? This is your solution! Maybe you want a beautiful designs that will catch other pilots eyes as well as it catches thermals. She is a very advanced aerodynamic flying wing that performs! Be sure to check the videos below to get an idea of her performance.
Glider Fuselage:
Electric Fuselage:
The 2 meter wingspan and super low wing loading combined with an RTF weight under 20 oz makes catching even the weakest lift possible. When you're done specking out in that big boomer thermal, use the spoilers to bring her in. The two piece wing makes transport easy while powered and unpowered fuselage options allow for slope, hand launch, Hi start or flatland flying. Features an all CNC cut wood and carbon spar construction and quality, easy to follow build plans.
Specs:
- F3L (RES) => High start
- F5L (E-RES) => Electric motor
- Wingspan: approx. 2m
- Wing Area: 43.6 dm²
- Wing Loading: 10 g/dm²
- Weight: 440-500g
- Controls: Elevons, Spoilers (Motor if electric)
Features:
- The spoilers are very easy to control as there is no load change.
- The receiver is housed in the wing => this means that one receiver can be used to operate both glider and electric power systems.
- Due to its wing-divisible design, the REPUS is very easy to transport.
- The REpuS complies with the competition regulations of the FAI classes F3L (formerly RES) and F5L (formerly E-RES)
- A ballast chamber at the center of gravity makes REPUS usable even in freshening winds.
Intended use:
Thermal soaring galore! Whether you launch it by hand (which works much better with the fuselage club) or with the high-start rubber band or a 22mm outrunner motor.
=> With the REPUS, many things are possible!
Have a look at these flight videos that show the true performance of this highly engineered design.
Hand Launch:
Sloping in VERY light lift:

A competitive design!
- COMPETITIVE SUCCESS for the REPUS!
Franz Heindler and his REPUS secured 3rd place in the F3L-RES competition at the 2023 Upper Austrian State Championships.
- F5L competition in Lockenhaus on May 31, 2025: 27 participants, sunny weather, light winds, mostly thermals. REpuS takes 2nd place.
- June 2025 - Lockenhaus, Marco Bierbauer took first place with 21 participants at the F5L competition in Fürstenfeld with his REpuS. Congratulations!
- Marco Bierbauer with REpuS is back in the FlyOff! On June 15, 2025, the F5L competition took place in Feldbach (Kornberg Cup + Styrian Championships). He finished 5th in the Cup competition and 2nd in the Styrian Championships.
- Marco Bierbauer and his REpuS glider have achieved further success in Triestingtal: In strong winds, he landed five 1000-meter flights in the preliminary round and finished 2nd after the fly-off, out of a total of 16 participants, all of whom were F5L specialists. Congratulations!
