Hi Thrust Viking (oz9480)

About this Plan

Hi-Thrust Viking. Free flight model for .049 to .051 power. Wingspan 48in, wing area 330 sq in.

Quote: "THE outstanding development in the free-flight models of recent years has been the 'high-thrust' type of ship. The great advantage is the ability to get away from the looping tendency of normal pylon models. Of course, this can be done with a lot of down thrust too, and some very successful designs have proven this to be a good, practical answer. However, in order to avoid forces fighting one another, causing excess drag, it seems logical that the thrust line should not be at a great angle to the wing. High thrust line position allows a small angle.
Surprisingly, the idea of high thrust line is not new at all. It was tried from time to time over the years by many modelers. In fact, early Model Airplane News editor Charles H Grant showed this idea more than 25 years ago, and I built a small indoor model to try it out at that time. Strangely enough, for a long time the merits of this feature were unable to make a deep impression on modelers generally. Stan Hill's Amazon (oz2688), Walt Schroder's Jersey Javelin (oz9487) in 1940 and other designs were among the first to create interest. Then, about six or seven years ago, during an FAI spring elimination meet in Chicago, Jack Greene of South Bend, Indiana, flew his high thrust job, and it aroused the interest of Russ Hansen and Gerald Ritz..."
