About this Plan

Grumman Hellcat. Free flight rubber scale model.

Quote: "The unsung hero of the Pacific theatre, Grumman's durable fighter amassed impressive service records in short order. Rubber Scale F6F-3 Hellcat, By Mike Midkiff.

Designed specifically to combat the fast, nimble Japanese Zero after the outbreak of the war, the unsung Hellcat methodically and systematically eliminated almost all Japanese fighter opposition during the final two years of the war. Strangely enough, she never got the accolades literally heaped upon her more glamourous teammate, the F4U Corsair.

In a humble attempt to set the record straight, let's compare: Kill ratio: Corsair 12-1; Hellcat 19-1! Carrier landings: the Corsair required almost the entire war to solve carrier landing problems. The Hellcat could literally 'stall and fall' in a controlled attitude until the deck came up to hit the gear. Speed: the Corsair was marginally faster at low altitudes, but at 10,000 feet they were even and at 30,000 angels, the Hellcat pulled away.

As further proof of the F6F's basic soundness and efficiency, there were only two variants produced through the war: the F6F-3 and the F6F-5: Both models totaled 12,274 aircraft produced by war's end, which amounted to over eleven aircraft per day! Truly this was an amazing production feat and a tribute to the basic simplicity and functionality in the Hellcat's design. Perhaps the greatest tribute paid to the Hellcat was by Navy ace Gene Valencia of VF-9 who once remarked: I love this airplane so much that if it could cook, I'd marry it.

The model represents an F6F-3, which was flown by VF-1 aboard the Yorktown sometime in 1944. At 3/4 in = 1 ft scale, she is rather large as far as rubber power scale models go. Originally, my model had knock-off wings and adjustable ailerons, but I left them out of the design because little was gained to offset the added weight. I did however retain the plug-in landing gear, as this gives one the option of flying with or without the gear.

Due to the size of the model, near scale airfoil thickness is a must for the wing, stab and rudder, or she just doesn't look right. Consequently, some attention should be paid to careful wood selection to keep the weight no more than six ounces all up. I have used a semi-scale 3-bladed prop of about 11 inch diameter with satisfactory results, but a 2-bladed 12 inch diameter prop would be at least as satisfactory.

Construction notes. A model of this size and bulk requires extreme care in the selection of balsa wood to give adequate strength, yet at the same time minimum weight. With this in mind, the fuselage should be constructed as lightly as possible using hard balsa only for the 3/32 basic box framework. All other areas - formers and sheet fill-in - must be made from light balsa. The wings should employ only medium to medium light balsa for leading and trailing edge stock and all ribs. Only the spar material should be medium to hard. All balsa blocks should be hollowed out and, in addition, be of the lightest balsa possible..."

    ScaleType: This (oz3488) 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_F6F_Hellcat
    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.

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.
