Interesting cost comparisons. Well, it is a given they are both biplanes but with different airfoils and the Alexander Eaglerock long and short wing versions had balanced rudders. The OX-5 engine is of 90 Hp but the OXX-6 of 100 Hp was also used, but sparely as it was so much more expensive. Performance of the Alexander Eaglerock was far below in all respects that of the Paul Poberezny much later design. Appearance wise? Somewhat homely vs. sleek. The age difference benefits the latter design of Paul's in so many ways that it is hard to find similarities other than both being open cockpit biplanes. The latter day design may be harder to fly well as things happen more rapidly in its flight characteristics.
Incidentally, the late Albert Mooney first worked for Alexander in Colorado on the Eaglerock designs under the Chief Engineer Daniel Noonan. We all know of Mooney's ensuing fame. I highly recommend reading "The Al Mooney Story (sub-captioned) They All Fly Through The Same Air, as told to Gordon Baxter. Shearer Publishing, 1985, Fredricksburg, Texas. A compellingly great read that covers the M-1 through M-23 designs of Al Mooney from 1925-1968. He also designed aircraft for Marshall/Montague, Bellanca, Dart, Monocoupe, Culver and Lockheed-Georgia. _________________ PP ASEL
