I also offer plans for the Omega and more than 20 other combat designs in my eBay store -
http://stores.ebay.com/airclassixThe Omega is a really quick, easy build - and pretty rugged! The horizontal spar gives it considerable strength and warp resistance. The ribs are all identical - center section is planked, cap strips on the others. I've built them in an evening and covered them the next day, though I wouldn't particularly recommend it.
One of my craziest memories from the '50s is of sitting in the back seat of a car on the way to a contest, rain pouring down, windows rolled down, and I'm doping the silkspan. Only to fly in fairly heavy rain and lose in the first round anyway!

The airplane comes out quite light and performs very well for something of that era. I built several and powered them with a variety of engines, starting with the lowly Fox .35 Stunt.
My other vivid memory of the Omega: For most of the '60s and '70s I flew small, light wings powered by cleaned up Fox 36Xs running 30% nitro fuel. In 1964 at Iowa City, Iowa in the finals I was matched with a contestant flying an Omega with an OS Max engine. To this day, I can only imagine what had been done to his engine - it was one of the very few times in those years that a competitor matched my speed - with an upright engine, no less!
