The Worlds Most Advanced Paper Aircraft Model

EARco provides patterns that are easily cut out from the paper patterns in the kits provided. On the patterns are attachment, folding and taping instructions. The result is a tough and realistic aircraft that's fun & easy to fly and build. Every major wing surface is double thick to be tough and have an optional internally (spar) support. All model aircraft come with all the instructions to build a 1/80th scale

I-1B INDUCTOR Design Theory: The horizontal fins (stabilizer) on the INDUCTOR is placed on the bottom of the fuselage, and the main wing on the top. The main wing causes air to down draft when it generates lift and makes the air unstable at low speeds. So placing the horizontal fins outside of the main wing's wash keeps it functioning without problems caused by the main wing. The main wing is swept at 45 degrees. This is a simple wing to build, is robust, and has a generous area, (moderate performance aircraft like the F-15 Eagle are built around this formula). The vertical fin is tall and generous. This creates stable flight by holding the aircraft vertical. Finally, the fuselage is open at the back. This serves to create air resistance by suction resistance, stabilized flight, and keeps the performance easy.

	I-1B INDUCTOR: Ranks (*) Construction Time: 15 - 60 minutes Performance: Designed as a training aircraft, it's easy to build and fly. Scale speed 1200 MPH. Tech data: Wing Span, 6 inches. Length 10 inches., Weight 9 grams. Comments: Awarded the The World's Finest Paper Aircraft in 2001.

S-1A SCORCHOR Design Theory: Evolved from the I-1 INDUCTOR, the SCORCHOR has highly swept (60 degree) wings, this feature increases the robustness of the main wing and streamlines the design. The vertical vortex control fins on the main wing tips control lift near stall speeds, stabilizing the SCORCHOR at lower speeds. The vertical and horizontal fins are minimized to reduce air resistance and spurious inputs at high speeds. The fuselage is tapered to minimize suction drag. A noteable disadvantage at higher speeds is the top mounted main wing. The armpit of the SCORCHOR causes viscosity because of the narrow space between the bottom of the wing and the fueslage. This restricts its high speed performance and range.

S-1A SCORCHOR: Ranks (**) Construction Time: 20 - 90 minutes Performance: High speed (exceeding 2000 MPH scale speed), medium range, light weight aircraft. Fully qualified for moderate thrust (PussyCat) catapult operation. Tech Data: Wing Span 5 inches, Length 10 inches, Weight 7 grams. Comments: A highly futuristic design, incorporating vortex control fins on the main wing tips, perfected and well able to exceed the much touted INDUCTOR's performance. The SCORCHOR intends to win the Worlds Finest Paper Aircraft Award in 2002.
