1:72 Me262 Hg III

 The HG series of Me 262 derivatives was believed capable of reaching transonic Mach numbers in level flight[citation needed], with the top speed of the HG III being projected as Mach 0.96 at 6,000 m (20,000 ft) altitude. Despite the necessity to gain experience in high-speed flight for the HG II and III designs, Messerschmitt made no attempt to exceed the Mach 0.86 limit for the Me 262. After the war, the Royal Aircraft Establishment, at that time one of the leading institutions in high-speed research, re-tested the Me 262 to help with British attempts at exceeding Mach 1. The RAE achieved speeds of up to Mach 0.84 and confirmed the results from the Messerschmitt dive tests. The Soviets ran similar tests.
