About this Plan

Hornet. Free flight power model.

Note this is not a full size plan, this is a scan of the article and drawings as they appeared in the magazine pages in 1940.

Quote: "Building The Hornet. Complete Data to Build A Low-Drag High-Performance Gas Model That Gets Up Quickly and Stays There. By Sal Taibi.

WHEN the Academy of Model Aeronautics met some time ago the 1940 gas model rules were devised, and we immediately sat ourselves at the old drawing board and scratched our head in search a design that would be 'tops' under the new regulations.

Of course, we're in favor of big ships with plenty of area and a maximum of stability and performance. Those were our prime considerations and the Hornet finally emerged as the plane we wanted. It combines all the features we desired, plus streamlining, in a design that is simple to build, easy to adjust and pleasing to the eye. Under power it climbs in a left corkscrew. At the top of the climb it rolls out into a flat, level glide to the right. The Hornet really performs like a champion and it's our top ship for 1940.

The first test flights were uniformly successful. The first flight, which was made with a 20-second very low power motor-run, demonstrated to us that the ship had the inherent stability we had sought and that the glide was perfect. After making minor adjustments, gradual increases in power were made until finally the ship was ready for a real flight - and what a performer it proved to be.

From a standing start, with absolutely no hand-guidance, the ship amazed all witnesses by consistently doing 1:40 on a TEN SECOND MOTOR RUN. What about a 20-second motor run? Sorry fellows, the ship goes too far and performs too well for it to be risked on test flights, but if you really want to see what it does on a 20-second motor run, we are sure it will live up to this bright promise of long flights.

Building and Flying: The first step in building the Hornet is to scale up the plans to full size. Ordinary bond paper may be used for this process, which may be obtained at ally stationery store for about a dime a roll. In scaling up a plan the builder will learn more about the construction of the model than he can in any other way; points of construction which looked complicated in the smaller plates will become perfectly clear when seen in actual size. Scales are given under each particular section. some parts have been drawn quarter-size, some full-size, others one-eighth size. Careful study will result in clear, easily understood plans and subsequently in a well-built ship.

The Fuselage: The first step in building your Hornet is to lay the lower longerons on the plan. (Build two sides at the same time - that is lay one logeron atop the other.) These bottom longerons, which take a greaterpart of the shock, are of very hard stock. Top longerons may be of medium stock and it will be noted that these top longerons are doubled at the cabin. After these longerons have been placed on the plan, the A and D braces are inserted and the thrust-line longeron (which is 5/16 x 5/8 stock) is cemented in place. The remainder of the fuselage is of conventional construction and may be easily followed in the plans.

After the two sides are built allow them to dry for several hours. While these sections are drying, cut out the main bulkhead (A) from 1/4 birch plywood. The sides of the fuselage are then removed from the board. Assembly starts at this point by placing the bulkhead between the fronts of the fuselage sides and cementing in place. This bulkhead automatically squares up the fuselage assembly. The rear of the fuselage is tapered and cemented and the rest of the braces are cemented in place according to plan.

The motor mounts and landing gear are cemented in place. A careful study of the plans will make this process relatively simple. The fuselage skids, of 1/8 wire, are bound to the lower longeron with linen thread and the 'tie' is cemented. The bulkheads and stringers are then cemented in place. The sub-rudder is formed and cemented, and as the final fuselage assembly step, the tail skid and tail hook and dowels to hold swing and tail are inserted in proper places and cemented. All joints should be cemented thoroughly at least two or three times.

Ignition: A carefully wired ignition system will repay the builder many times in efficient operation. The plan should be followed very carefully in this step. All connections should be soldered, as the connections are made on the ignition platform, which is finally cemented into place.

Nose Block: The nose block is a work of art, but is really simple to build. The center portion is built of 2 x 3-1/8 inch soft balsa, as shown by dotted lines on the plans. After this has dried it is cut to the solid line outline on the plan. Sides are formed of 5/16 sheet which are cemented in place to complete the cowl. The motor should be mounted before the cowl is finished for your mounting may vary in slight respects..."

* 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.
