Omen III

Omen III

Don Wilke’s “Omen II” from 1968 is one of those birds that just grabs your attention and won’t let go. I’ve had my dad’s 1968 RC Modeler magazine for years, and there was something that kept bringing me back to it. It seems to have the classic early pattern proportions, perfect for today’s sport models. The raked fin and slick turtledeck give her nice lines, and the long tail moment screams “smooth.”

Fast forward 46 years, and electric power is now practical, affordable, simple, and reliable. Ah ha! Let’s shrink down the 92-inch original design and simplify it. Many of the older pattern ships make great sport models today, and I thought it would be a sure winner designed around the reliable E-flite Power 46-size setup. So here we have the result, the 63.5-inch-span Omen III. It is an all-wood design, with a minimal parts count. I’ve used standard size woods throughout, switched to a fully symmetrical wing section, and gotten rid of half the wing ribs. I went from one aileron servo to two. The prototype was built from design start to finish and ready to fly in seven weeks of evenings, so your model will go even faster! The finished ship is only 4 pounds, 12 ounces with a 4S 4000 battery, for a light 19 ounces of wing loading and a healthy power loading. She’s even lighter with a 4S 3700mAh pack.
