About this Plan

F8F Bearcat Gulfhawk. Control line scale model. Wingspan 35-1/2 in, for K&B .35 engine. Scale is 1/12.

Quote: "The plane was stripped of its battle dress, such as rocket brackets, guns, and radar equipment, making it 1,300 lbs lighter than its Navy counterpart. Powered by a Pratt and Whitney R-2800 engine, the ship could climb to 5,000 ft in 97.6 seconds from a standing start at speeds in the 450-500 mph range. The world's fastest prop-driven airplane, the Bearcat missed the war in the Pacific by only a few weeks and only 120 planes had been completed at the war's end. This colorful model, flashing a glass-like finish of orange, blue, and white, was flown by Major Williams from 1948 to 1950 when the plane was destroyed by fire in a landing accident at New Bern, NC.

Our model is constructed mainly of wood, silk-covered, and finished with dope, with detail work done from Willis Nye's plans. Accurate information was obtained with the cooperation of the Gulf Oil Company in Pittsburgh. The plans are drawn primarily with the scale builder in mind, but may be readily modified for sport or carrier flying. The 1 in to 1 ft scale model weighed about 4-3/4 lbs when completed, including a 1/2 lb nose ballast. I used medium and hard balsa throughout the construction. When building, one might keep this in mind and use materials considerably lighter in the aft section. The model can be built much lighter.

My Gulfhawk features operating cowl-flaps, droppable belly-tank, sliding canopy, shock-absorbing landing gear and tail wheel, wing-tip and tail lights, throttle cut-off, and functioning landing flaps actuated by 'down' position from the handle. It is powered by a K&B 35 equipped with a Johnson throttle; the cowl flaps are connected to the throttle linkage, opening on low speed and closing on high speed.

The auxiliary tank is released by throttling from high to low speed. All the lights are operable on low speed. Wing flaps were hooked to a reversing cam and toggle and, when given a full down, the flaps are lowered; when given full down a second time, they are retracted. A simplified version of flap linkage is shown on plans.

The landing gear should be the first item of construction. Except for the wheel axles and pins, most of the parts were rough-sawed aluminum, shaped and finished by hand filing. The cylinder is the only completely machined part. The landing gear support bracket and cylinder are pressed together. Press on the cylinder knee lug. Do not pin the shock strut in place until the model is ready for finish, since the spring tension will have to be determined by the weight of the model.

Tread on the 2-1/2 in Veco wheels is filed off by mounting them in a drill or lathe and using a coarse file. By filing off the tread, you will come fairly close to the 2-1/4 in scale wheels. The tail wheel is also filed flat on top and the sides are squared. Assemble the tail wheel..."

    ScaleType: This (oz15096) 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.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Grumman_F8F_Bearcat
    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.

User comments

The correct designation for this airplane is "F8F". The title of this plan page and sidebar text incorrectly has it as "F-8F". The plan itself incorrectly refers to it as an "F-8-F", while the article text has both "F8-F" which is wrong, as well as the correct "F8F". Listing it with the correct designation of "F8F" would help searches immeasurably.

Ok, I'll go for that. Let's rename this one as F8F. Just so we're clear, it will make no difference to searching, the Oz search ignores (strips out) any "-" characters within titles, so search results will be unchanged. But once you get to the page, it will look better :)

Notes

* 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.

Scaling

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.
