Question:  Who designed the BIG IRON?  I was always under the impression that Carl Berryman was the designer of this well known combat plane from the 1960's.  The last MODEL AVIATION issue had an article on C/L Combat which indicates that Marvin Denny was the culpret.  If that is true, I have been under the wrong assumption for all these years.  Is there anyone out there who flew the BIG IRON in competition in the 1960's/70's contests?  Since I never got around to building a BIG IRON, I am wondering, how did this plane compare with the VOODOO and the OKLAHOMA TWISTER....just wondering.  I guess you learn something new every day.            

  As for performance, I think that the Bigiron was quite a bit better than the Voo Doo.  The Voo Doo was MUCH easier to build, but the bigiron would survive a collision much better than the Voo Doo  when using the engines of that period of design.  As engines became larger and more powerful the collision advantage went away to some extent.

  Terrence, are you talking about the "Oklahoma Twister" which looked a lot like the Bigiron or the "Super Twister" which was an Elliptical wing design?--  either way, neither of those two was as good as the Bigiron.---- Now the "Phantasy" was another thing!1  It was far superior to thwe Bigiron, but for me, too hard to build.
  As engines became larger and more powerful, I simply enlarged the Bigiron to take care of the added weight and still called them the Bigirons--- even when I changed from twin booms to a "box boom" fuselage .
  A couple of years back, I took the "percolator down off the wall and with a ST G-21/35, put is a couple of 100+ MPH flights.
