About this Plan

Emanon. Control line proto-speed model. For K&B .29 engine.

Quote: "Holder of the Class B Proto Speed record at 151.20 mph, this light-weight design is a many-times contest winner. Emanon, by Jim Delaney & Tom Lauermann, as told by Pat Flinn.

THE Emanon holds the AMA Class-B Proto Speed record of 151.20 mph. It's name is 'No Name' spelled backwards. The design is the culmination of a series of proto-speed airplanes developed by the speed team of Tom Lauermann and Jim Delaney, both from Chicago, Ill. The design dates back to the Fox .29X days. The ship first broke the record at the 1965 King Orange Internationals with a proto speed timing of 143 mph.

A proto speed ship is timed from the instant of release until the completion of the 14th lap, one mile. Contrasted to Proto a Class-B pure speed plane becomes air-borne and gets a flying start for a much shorter, seven laps or 1/2-mile, clocking. Proto may be compared to an auto drag racer, except that the strip is four times as long. 'B' speed is comparable to a Bonneville Salt Flats flying mile, except that it is shorter, only a half mile. Because of the increased distance, acceleration is a factor. The engine must peak immediately as soon as it hits the air. Proto speed is considered to be one of the toughest of all of the speed events.

As in any speed event, an excellent en-gine is of utmost importance. In Proto, however, the airplane itself plays a propor-tionally greater role than in the pure speed events. I believe that Howard Weaver and I adequately proved this point when we used our copy of the design, powered by one of John Barhardt's rat-race engines and fuel, to take second at the 1968 Olathe Nationals.

Another advantage, or disadvantage, depending upon your point of view, is the apparent unsuitability of the newest development in speed flying, the tuned exhaust pipe. The pipes presently being used give an impressive boost in the air but require a number of laps before the required resonant rpm is reached and they 'come in.' Their increase in weight also presents a serious problem. Anything that harms the first lap is disaster in a Proto run, for a poor first lap equals a poor Prato time, always.

In short, this airplane fills the requirements of a good Proto ship, ie dependable takeoff characteristics, lightweight for good acceleration, and stable flying habits coupled with a clean design for maximum air speed. However, this is definitely not a beginner's ship. It is strictly built for high performance at record or near record speeds. It is rugged enough to take any of the loads imposed upon it in normal flying, but one goof and you start over. Build heavy and the performance of any Proto drops off drastically.

Good craftsmanship is important throughout construction. Accurate alignment of the surfaces will go a long way in determining the ultimate performance of any airplane. Careful wood selection is important..."
