Howard Ike (oz10641)
About this Plan
Howard Ike, Howard Mike. (Howard DGA-4, DGA-5). Control line scale model 1930s racer.
Plan shows both DGA-4 (NR55Y) 'Mike' and Howard DGA-5 (NR56Y) 'Ike'/'Miss Chevrolet'.
Quote: "One of the most popular racing planes to be duplicated in model form during the past three decades is the Howard Ike. This attraction to model builders is readily under-standable when we observe the clean, uncluttered, simple lines of the design which are not only pleasing to the eye but also reflect the fact that this, plane is easy to build, The beautifully enclosed engine unquestionably contributes to its attractiveness.
Successful race plane designer and air line pilot Ben O Howard developed the gleaming white Ike and its twin, Mike, during the 1930-1940 racing era following his outstanding Pete design. The Ike-Mike design attained its highest racing average speed when it won the Greve Trophy Race in 1935, piloted by Harold Neumann, at 213 miles per hour. These craft also placed in the Thompson Trophy Races of 1933, 1934 and 1935. Ike was powered by an air-cooled, inverted, six cylinder, 200 horsepower, Menasco engine.
The Ike was so small that the upper portion of the fuselage in way of the cockpit was removable in order to allow the pilot to enter the cockpit. When the cover was in place only the pilot's head protruded through the cockpit opening.
Our model is built to the scale of 1-3/4 in equals one foot. This size produces a model that can comfortably accommodate any engine from .19 to .35 cubic in displacement completely enclosed within the cowl. Despite the fact that the full size plane was fabric covered, the prototype model is covered with sheet balsa for strength and durability. Ribs are simulated with plastic fish line for a true scale effect. Scale rib spacing is shown on the plans.
Before construction is described, the author wishes to express his sincere appreciation to Mr Myron E Scott of the Chevrolet Division of the General Motors Corporation, for his kindness and assistance which made this article possible.
Construction begins with the wing. Cut the plywood wing joiners and the spar to shape and cement the joiners to the spar halves. While this is drying, the ribs are cut to shape. Cement the ribs to the spar and leading edge and then prepare the wing lower covering. Cement the lower covering to the ribs and leading edge and hold in place with pins. Note the absence of the center rib.
Attach the lead-out wires to the com-mercial bellcrank and bolt it to the hard-wood mount. Add the wire control rod and cement the bellcrank mount to the spar, ribs, and lower covering as shown; passing the lead-out wires through the holes in the ribs.
Carefully bevel the leading and trailing edges of the lower covering to follow the contour of the rib upper camber. The upper covering is added now; be sure to cement it to the bevelled portion of the lower covering as well as to the ribs and spar. A slot must be cut into the upper covering, to accommodate the control rod, before it is cemented in place. The wing tips are laminated with sheet balsa and cemented in place to the spar and tip rib. Note the lead-out wire tubing in the in-board tip which is inserted during the laminating operation..."

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
