Sporty II (oz7049)

About this Plan

Sporty II. Free flight gas model.

Quote: "Designed strictly for stable, realistic flying, Sporty surprised everyone, including the author, by performing better than the average pylon job because of the well-balanced force arrangement. The prototype won a first-place trophy with a flight of over 17 mins OOS; another model of the same design won three medals and an engine. This was back in 1940. In climbing, the nose does not point skyward as on most designs, but the model certainly gains altitude in a hurry. There is no appreciable dip when the engine stops, partially due to the comparatively short tail moment-arm. Center of lateral area is low, affording excellent spiral stability, while the thrust line is high to prevent excessive nose-up moments and consequent looping under high power. The airfoil was designed especially for models and is neither extremely high nor low speed. An inverted Tiger-Aero engine was used on the original model and this was lost OOS. A second ship was built using an upright Mighty-Midget which performed with equal success, but was recovered. The design is stable enough to handle the power of a .60 cu in engine and a light model should perform well with a .30 cu in power plant. Our latest version is glow-plug powered, with an Ohlsson .29 up front and performance is better than ever..."

Quote: "Hi everyone- this is Walter Musciano's Sporty article scanned directly from my issue of Model Airplane News November 1950. Sporty is a 65" span 600 square inch cabin model dating from 1940. it reminds me of a larger So-Long but certainly has the designers distinctive touch.... this model would make an excellent flyer today using any power system. this has been shared with outerzone.. enjoy,"
