One of the strangest helicopters you have ever seen is going back into production. Following a 12-year hiatus, the Kaman K-MAX K-1200 heavy-lifter, first built in the 1990s, will again start emerging from the factory after the Connecticut-based manufacturer received an order for 10 helicopters from two operators.
First type certified in 1994, the K-MAX is unusual for its intermeshing twin main rotors, the same basic principle used in Charles Kaman’s first prototype helicopter in 1947, the K-225.
