Starstream (oz15733)

About this Plan

Starstream. Free flight sport model with ducted prop layout. Wingspan 30-1/2 in.

Quote: "Starsteam. Ducted fun! Ray Malmstrom's prop-in-a-box sposrtster is described by John McIntyre.

Starsteam is a beginner's ducted fan model; well, not really a ducted fan, more of an engine churning air around inside a box with holes in it. Some of the air leaks out and pushes the plane along.

This abysmal inefficiency yields a docile aircraft. Engine thrustline is irrelevant. Startsream has continued to fly with 30 degrees left side thrust and 15 degrees downthrust caused when one of the engine mounting bolts came undone, though it made a noise like a dying spin dryer as the prop chewed its way through the fuselage.

The original model is powered by a Cox TD .010, but a second has now been built powered by a Pee Wee .020 with three bladed prop [pic 004]. This version flies just as well, so as the Pee Wee is still readily available - unlike the lamented .010 - we have shown this motor on the plan.

I first saw Starstream fly back in 1976. Ray can usually be relied upon to arrive at the flying field with an interesting model and that Sunday was no exception..."
