Quote: "Texas A&M's AG-1 Free Flight Scale. An aluminum-bender's classic, this crop duster makes a fine F/F scale; you see it for U/C too, no?

Realizing the need for a good crop-dusting plane, Texas A&M Aircraft Research Center designed the Ag-1. The airplane's sole purpose is dusting, spraying. seeding, and fertilizing.

The craft was constructed under a CAA contract. The project had the benefit of personnel assigned for various periods by CAA, the Department of Agriculture, two airplane manufacturers, and the Texas A&M College System: many important parts including the engine, propeller, landing gear, and seat were contributed by their manufacturers.

Estimated performance of the airplane under full load conditions is unusual; maximum speed, 115 mph; cruising. 100 mph: operating speeds, 60 to 90 mph; landing, 45 mph (normal landing without pay load, 37 mph); rate of climb 600 feet per minute; service ceiling 12,000 feet; cruising range 400 miles; and take-off distance to a height of 50 feet is 1300 feet.

Full span slotted flaps and slot-lip ailerons give ultra-maneuverability which is required for its given work. We thank Mr Fred E Weick and his staff at Texas A&M for their technical assistance in the preparation of the model. which is a direct copy of the original with little modification except where needed for free flight. All of the model's surfaces are sheet balsa covered, which not only adds realism, but strength for rough landings.

We were very pleased with the performance of the model Ag-1. The Cub .074 proved perfect for all purpose flying. Building data on full-size plans."

    ScaleType: This (oz14500) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.

    ScaleType is formed from the last part of the Wikipedia page address, which here is
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

* 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.
