Tony Radmilocich, PC Pilot Magazine:
"If you love hands-on, high adrenaline flying, the early Learjets should be your cup of tea. Xtreme Prototype's 24/25/28 models capture the essence of what it is like to pilot one of these little "rocket ships" in corporate jet guise."
Emmanuel Blanchard, Micro Simulateur Magazine:
"The numerous aircraft systems are realistic and plunge the virtual pilot in a pleasant environment of before the electronic era. Pleasant to control, offering feelings rarely encountered while flying a business aircraft, the 20 Series deserves the interest of the virtual pilots."
William Werrlein, FlightSim.com:
"For those of us who wonder how the basic jet feels I would recommend this aircraft (20 Series). I really do think that Xtreme Prototypes has done a great job in their level of detail on the exterior and interior, and the flight dynamics of the aircraft. As for the manual I must give a round of applause for the developer."
"Xtreme Prototypes has produced a most pleasing add-on Lear 20 Series jet. The design is a compromise that will be easy for new users to enjoy and has sufficient detail that more experienced users will not find it boring, or toy like. The flight model is good, with accurate roll and pitch response for the 20 Series Learjet. The Xtreme Protoypes Lear 20 Series is a lot of fun to fly."
PC Aviator (A Current Best-Of-The-Best List For Flight Sim Pilots):
"If there's a company that has impressed the heck out of us with their approach to quality and professionalism, it's Xtreme Prototypes out of Canada. They are nothing short of a world class act... Their latest addon emulates several models of the Gates Learjet 20 Series and is a must have addon to your hangar."
Joe Zerilli, 20 Series fan and ex-pilot:
"I must say, I simply love your 20 Series Lear collection. Truly a masterpiece series. I have real world experience with the 25D, and still have all the training manuals and documentation on the aircraft."
