What's new in version 4?
A Fighter in Civilian Clothing
Nicknamed “fighters in civilian clothing” because of their sleek design and amazing performance, the classic Lear Jet/Learjet 20 Series aircraft were the first true executive jets and redefined business aviation during the 1960s and 70s, flying high above the weather at transonic speeds. Their capabilities earned them a place among the extreme aircraft, setting record after record.
With the longer-range Gates Learjet Model 25D came a longer cabin, increased seating capacity, more flexible loading options, greater fuel capacity and a rather sleek-looking stretched fuselage. It is fast, slim, sexy, comfortable and capable of maneuvers you would never attempt with another civilian aircraft. According to some real-world pilots, its performance as a general aviation business jet is simply unequaled, even by today’s standards!
A Unique Addon for your Hangar
The Xtreme Prototypes GLJ Model 25 v4 is a next generation addon optimized for the latest versions of Prepar3D and designed to take advantage of the new and more powerful gaming computers and graphics cards that are available today. Nothing was spared in our efforts to reproduce the different instrument panels, carefully modeling and animating each mechanical device with all the necessary moving parts. Except for the LCD screens and the radio’s VFD displays, no flat 2D gauges are used in this model. Everything you see is in full 3D!
The result is a unique addon that strives to bring you not only the actual feeling of flying a high-performance aircraft now equipped with modern avionics, but also the spirit of maneuvering such a vehicle at times where large LCD screens and powerful computers didn’t exist, and where pilots needed to know how to fly and navigate with minimal resources and rely on their own experience, abilities, and judgment.
At Xtreme Prototypes, we consider our addons as real micro aircraft simulators rather than just games. Our products take months if not years to develop and test by a dedicated and passionate team of artists, technicians and pilots. We pay attention to every detail and we do our best to make sure that we provide our users with the best flight simulation experience they can get within the limitations of the current simulation platforms. We believe our GLJ Model 25 addon (and our GLJ Model 28, available separately) is the most advanced, detailed, and faithful classic Learjet simulation you can find.
Designed by Users for Users
Becoming one of our users makes you an important member of our development team. Version 4 of our GLJ Model 25 addon is the product of the many ideas, comments, and suggestions we received from desktop pilots like you from around the world since version 1 of our 20 Series business jet addons was launched back in 2009. We wish to express our gratitude to all our users, followers, reviewers, test pilots, ex-Learjet employees, partners, and friends for their contribution to the making and success of this extreme aircraft simulator. Thank you for your continuous support!
