Announcing our GLJ Model 25/28 Addons for Microsoft® Flight Simulator 2020
Our classic Gates Learjet Model 25/28 business jet addons for Microsoft® Flight Simulator 2020 are currently in production and will be released later in the year. Please note that Xtreme Prototypes has ceased producing new addons for FSX. More details to come.
Version 3 of our GLJ Model 25 for Prepar3D® and FSX Still Available for a Limited Time
The Xtreme Prototypes GLJ Model 25 Special Edition v3 addon is currently our most advanced, award-winning, study-level business jet simulator for Lockheed Martin® Prepar3D® v5.x/4.5 and Microsoft® Flight Simulator X.
Peter Stark, PC Pilot Magazine (UK, July/August 2020):
"This most recent model in the series is not a simple upgrade but a major rebuild for FSX and Prepar3D… A fun, fascinating aircraft that exposes you to the skills required by the early Lear pilots as they launched into the sky. The Xtreme Prototypes GLJ25v3 is packed with features, animations and realistic behaviour, systems and impressive innovation. This makes it a very worthy recipient of the PC Pilot Platinum Award (95/100)."
Emmanuel Blanchard, Micro Simulateur Magazine (France, April 2020):
"If we had to describe this addon in two words, we would choose: ambience and behavior. The first to characterize the perfect rendering of an airplane from the 1970’s, with its numerous analog switches, controls, steam gauges, and systems that need to be operated manually, all accompanied by visuals and sounds which pay homage to these early days of business aviation. This one is no second-generation airliner, no light airplane, no fighter jet, but a mix of the three… And this is where behavior comes into play. This aircraft has unique flight characteristics and must be dealt with accordingly. It necessitates a pilot in the cockpit!"
New Dynamic Light Effects for Prepar3D® v5 with Hotfix 2 or Later (GLJ25v3)
Following the release of Prepar3D® v5 with Hotfix 2, we have noticed a few issues with some of the interior/exterior dynamic light effects in our GLJ25v3 addon which were originally calibrated for Prepar3D® v5 with Hotfix 1. A new set of light effects is available to fix these issues. This affects the Prepar3D® v5 version of our GLJ25v3 addon only if you have installed Prepar3D® v5 with Hotfix 2 (or later). Registered users can download the new light effects from their account page.
