[VSKYLABS Newsletter] issued 25 Aug 2024
It first got my attention last year, on the cover of Pilot magazine (March 2023 issue). At first sight, I assumed that the photo was of a unique replica/restored Junkers A50 Junior aircraft, brought back to flying condition as part of a historical recreation effort. Moments later, while reading the fascinating article I realized that it is an actual, modernized 'series production' S-LSA aircraft.

Following the detailed article, I initiated deep research, leading to the decision to develop the Junkers A50 Junior as a 'VSKYLABS' aircraft add-on for X-Plane 12. The main reason was that I really, really wanted to fly this aircraft, and a well-developed aircraft in X-Plane 12, optimized for the best VR experience, provides the closest flying experience one can get!
Next step was to acquire acknowledgement from ‘JUNKERS Aircraft GmbH’; The VSKYLABS development of the Junkers A50 Junior project for X-Plane flight simulator was approved by ‘JUNKERS Aircraft GmbH’. However, it is an independent VSKYLABS project which is not affiliated with ‘JUNKERS Aircraft GmbH’.
In this newsletter, we will go through a ‘short and effective’ presentation of the real-world Junkers A50 Junior aircraft, from 1929 to its rebirth as a modern S-LSA aircraft in 2022 and as an advanced and authentic flight simulation model for X-Plane 12.
If you are fascinated by the Junkers A50 Junior aircraft and wish to experience a close ‘look and feel’ flying of the modern S-LSA Junkers A50 Junior in X-Plane 12, you are welcome to visit the main project page on the VSKYLABS website in the link below!

The Historical Junkers A50 Junior
The Junkers A50 Junior, introduced in 1929, was a groundbreaking ultralight aircraft that perfectly captured the spirit of aviation innovation in the early 20th century. As one of the first sport aircraft designed with an all-metal structure, it featured a cantilever low-wing design made of a steel tube frame with duralumin corrugated skin. This design choice provided the aircraft with significant strength and reduced weight, enhancing its overall performance.

Engine and Performance
The original A50 variants were powered by a variety of 5-cylinder radial engines (providing ~79–87 hp), paired with a wooden propeller. This configuration allowed the aircraft to reach a top speed of 170 km/h (105 mph/91 knots) and maintain a cruising speed of approximately 150 km/h (93 mph/81 knots). The aircraft had a service ceiling of ~4,000 meters (13,123 feet) and could cover a range of around 600-750 km. These specifications made the A50 Junior versatile, serving roles such as sport flying and pilot training.
Records and Achievements
One of the A50 Junior’s notable achievements was its involvement in setting several world records, including long-distance flights. In 1931, Marga von Etzdorf became the first woman to fly solo from Berlin to Tokyo. She covered approximately 11,000 km using only compass and maps for navigation, unprotected from storms and rain in the open cockpit. Her journey took eleven days and demonstrated the aircraft's reliability and endurance over extensive distances.

Design and Structure
The A50's design was advanced for its time, emphasizing safety and pilot-friendly handling. Its all-metal construction marked a departure from the wood-and-fabric aircraft commonly used during that era, providing various advantages as an all-weather aircraft.
It featured a commonly Junkers convention of placing the pilot in the back-seat and the passenger in the front-seat.

The Modern Junkers A50 Junior
Based on the historical model of the Junkers A50 Junior aircraft, businessman Dieter Morszeck and his design team developed the new, modern and innovative Junkers A50 Junior aircraft, incorporating the latest technology. The aircraft had its maiden flight in 2021 and became an extraordinary ultralight S-LSA aircraft.

Engine and Performance Upgrades
The modern A50 Junior is equipped with the fuel-injected Rotax 912iS engine that delivers 100 hp. This is a considerable upgrade from the original rotary engines, enhancing the aircraft's overall performance and safety margins.
Modern Avionics and Safety Features
While the original A50 was minimal in terms of avionics, the new aircraft incorporates state-of-the-art systems suitable for the common ‘21st century pilots’. The new Junkers A50 Junior features a high-tech cockpit interface that blends elegantly into the retro design. The back seat (the main cockpit used for flying the aircraft) is equipped with a Garmin G3X Touch 10", while the front cockpit can host the Garmin G3X Touch 7" or GI 275 / Winter altimeter / Winter airspeed indicators (analog cockpit configuration is available as well).
The aircraft features a Galaxy parachute system and Beringer brakes.

Certification: S-LSA
On November 25th 2022, the Junkers A50 Junior was certified by the German Ultralight Flight Association. Then on February 28th 2023, the A50 Junior received its Special LSA approval from the FAA. The WACO Aircraft Corporation produces the aircraft for American customers.

The VSKYLABS Junkers A50 Junior for X-Plane 12 Flight Simulator
You are welcome to visit the project page at the VSKYLABS website: https://www.vskylabs.com/p/vskylabs-junkers-a50-junior-project/
Project Highlights:
- VSKYLABS 'Test-Pilot' Project.
- Superb Flight Dynamics: The VSKYLABS Junkers A50 Junior simulation is a highly engineered, robust tail-dragger S-LSA simulation model that makes use of X-Plane 12's sophisticated flight dynamics and physics simulation, pushing it to its limits.
- Simulated Systems: The VSKYLABS Junkers A50 Junior features X-Plane 12's latest native features, systems, and physics. This ensures 'high airworthiness' in X-Plane throughout its update process. Some systems may be restricted to X-Plane's default systems algorithms.
- General Cockpit Configuration: Equipped with a full-scale and fully-featured X-Plane 12 G1000 in a single-screen/dual-display configuration to allow maximum usability.
- Equipped with Alpha Systems AOA 'Eagle' indicator replica.
- Passenger Leaning-Aside Feature: For better takeoff and landing forward visibility (by demand via interaction/assignment).
- Built for VR: Development was tailored specifically for VR and optimized for 2D usage.
- Perfect Fit for Beginner and Expert Pilots: The aircraft is designed to be flown from the back-seat cockpit. This configuration requires higher piloting skills, and it will make you a better pilot! The front-seat cockpit is fully functional as well, with the limitations derived from the real-world Junkers A50 Junior front-seat operations.
- Wonderful FMOD sound package that includes authentic Rotax 912 engine recordings and an interactive set of dynamic sound layers that will "wrap" your open-cockpit flying experience, setting a whole new level of immersion!
- Autoupdater based on the SkunkCrafts autoupdater (XP12 only) - all updates are pushed smoothly without the need to re-download the entire base package (the base package will be updated every once in a while to minimize the gap).
- Highly Responsive VSKYLABS Support Forums: VSKYLABS offers continuous professional support, from aircraft-related aspects (operating and flying) to X-Plane technical support: Junkers A50 Junior
