Slo-Mo-Shun IV is presented here in scale model form. The scale is 1 in. equals 1 ft. The model planes like the real thing when powered by an Ohlsson & Rice .29 glow-plug marine engine. All drive accessories-universal, stuffing box shaft, strut, and shear pin-are also O&R products. A 1 1/2"x 1 1/2" prop is used. If more power and higher speed are desired, the hull is strong enough and stable enough to permit using an engine with a displacement as high as .65 cu. in.
A NEW world's one-mile record for unlimited: s was set by Slo-Mo-Shun IV on June 26, 1950, at Seattle, Wash. Driven by its owner, Stanley Sayers, . this Allison-powered craft flashed across the water at a' incredible 160.323 mph. The previous record of 141.74 mph had been set way back in 1939 in England by Sir –Malcolm Campbell's Blue Bird 11.
In hull .form, Slo-Mo-Shun - IV closely resembles the familiar three-step hydroplane. It is different however in one important respect it has a small V -bottom section at the bow. At speed, a conventional three step hydro rides on just the two side sponsons and the extreme stern.
