Background
The Aero L-39 Albatros is a high-performance jet trainer designed and produced in Czechoslovakia by Aero Vodochody. It
is the most widely used jet trainer in the world. In addition to performing basic and advanced pilot training, it has also flown
combat missions in a light-attack role.
About Model
The 50mm L-39 can be seen as a stepping stone to introduce RC pilots into the field of jets. Jets are generally faster and
harder to fly than most propeller-driven aircrafts, making them difficult for beginners, and sometimes even experienced
pilots, to fly. The L-39's unique airframe design and integrated main wing & tail effectively improve the low-speed handling
of the aircraft, significantly lowering the technical requirements. Meanwhile, the small-scale size (airframe length 808mm,
wingspan 659mm) reduces the site requirements, allowing pilots to take off and land at more sites away from crowds and
buildings.
The L-39, like other Arrows Hobby small-scale aircraft, comes without any landing gear to deal with, for higher speed and
better vertical performance. But rest assured, the anti-friction plate and servo housing at the bottom of the fuselage help
with this approach. Power comes courtesy of a 50mm 11 blade fan unit, 2627- 4500KV brushless motor and a high perfor-
mance 30A ESC (with 3A BEC), compatible with extremely common 3S batteries - giving unparalleled speed and sound.
L-39 has over half a century of history, with many classic paint jobs. Arrows Hobby has chosen a highly recognizable
silver-blue trim, with optional Air Force logo decal from multiple countries for the player to decorate their plane with.
