What's new in version 3?
A Fighter in Civilian Clothing
Nicknamed "fighters in civilian clothing" because of their sleek design and amazing performance, the classic Learjet 20 Series aircraft were the first true executive jets and redefined business aviation during the 1960’s and 70’s, 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, from which this addon is inspired, came a longer cabin, increased seating capacity, more flexible loading options, greater fuel capacity and a rather sleek-looking stretched fuselage.
Compared to flying other business jets, the Lear 25 gives you a thrill similar to racing a performance sports car and leaving all other competitors way behind. 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 SE is a next generation addon optimized for the latest versions of our favorite simulation platforms and designed to take advantage of the new and more powerful gaming computers and video cards that are available today. It is a complex aircraft simulator that features high resolution models and textures, hundreds of animations, over 60 sound effects, dynamic light effects, custom aircraft systems and full-3D VR-ready virtual cockpits that make this addon an ideal candidate for new virtual reality devices and applications.
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 new radio's VFD displays, no flat 2D gauges are used in this model. Everything you see on your computer screen 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 a time when LCD screens and powerful computers didn't exist and pilots needed to know how to fly and navigate with minimal resources and rely on their own experience, abilities and judgment.
For the general aviation desktop pilot, being able to hop between small regional airports while passing airliners along the way is quite a thrill, but for the serious IFR enthusiast, we are confident this package will provide years of flying pleasure. Even if there are some differences between this addon and the real aircraft, nearly all systems, instruments, switches and knobs are fully functional in order to simulate complete procedures, from cold and dark to shutdown.
Designed by Users for Users
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.
Becoming one of our users makes you an important member of our development team. Version 3.0 of our GLJ Model 25 SE addon is the product of the many ideas, comments and suggestions we received from serious computer pilots like you, from around the world. 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 the success of this extreme aircraft simulator. Thank you for your sustained interest and continuous support!
