About this Plan

Curtiss SBC-4 Helldiver. Radio control scale biplane.

Quote: "After paying off the mortgage and funding your children's education, what did you do? What I did was to fulfill a dream I've had for 50 years.

In 1941, at the age of nineteen, I bought a very expensive kit made by Cleveland. It was a Curtiss SBC-4 Helldiver. rubber powered, with a span of 25-1/4in. The wheels retracted up into the fuselage, and its pretend 500 lb bomb swung down from under the belly on a trapeze.

My inquisitive younger brother was 10 years old at the time, so I could not leave it in our apartment in 1943 when I entered military service. For safekeeping, I hung it in the front window of my parents' store. Two months later, my mother wrote to me in Mississippi, to tell me that someone had thrown a brick through our 8 ft plate glass window and had stolen nothing but my airplane, leaving me with only a few photos and memories. I vowed that someday I would build another.

In 1980, still dreaming about my stolen Helldiver, I wrote to Cleveland Models for a set of plans and put them away in my basement. Ten years later, when I started the process of retiring from business. I began planning for a radio controlled version of the Helldiver.

I had the plans enlarged to twice their size, but I then changed the wings chord-wise and in span by adding 4-1/2 in to the top wing and 4 in to the bottom wing; and in addition by adding 7% to the size of the tail surfaces. All the bottom wing ribs are alike so I rough cut and stacked them... "

    ScaleType: This (oz7911) 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.

* 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.
