CO2 Farman
AS MANY OF US fondly recall our modeling experiences back in the late 1940's, names like Campus Bee, Buzz, and OK conjure up memories of delightful hours spent building and flying models powered with CO2 engines. Compared with the cantankerous ignition engines, the one flip starting of these diminutive (next smallest were the Arden and Atom .09 gas engines.) little non-combustion powerplants was a sheer delight. Nearly every issue of the contemporary model mags contained at least one scale or sport or competition design for these readily available and inexpensive motors. Such familiar names as McEntee, McCullough, Willard, and Ehling often appeared on clever and well-tested designs. Numerous kits also were available ranging from beginner types to Korda's Powerhouse by Berkeley.
4-60
A SEQUEL to a highly-successful previous effort can often be a disaster-witness some of the really grim sequels we have all seen in movie theaters and in front of our TVs. Frequently the Goodmovie is followed by Goodmovie II, III, IV, etc. All are progressively worse. It seems that the creators have used all of their originality, skill, and inspiration on the first effort, and they have nothing left for the sequels. By some smile of good fortune, fortunately this sequel is even more outstanding than the original version. The 4-60 retains all the virtues of the 4-40 (December 1984 MA) and adds easier construction, higher strength, smoother aerobatics, and markedly-improved visibility.
