About this Plan

The Answer. FF gas model with Murray/ Ritz wing construction.

The Answer (oz3) by Gordon Scotty Murray was published in August 1940 MAN. This here is a later version from 1983. This plan and article is by Walt Musciano, who was also a member of the Brooklyn Skyscrapers model club in the late 1930s.

Quote: "The Answer and virtually identical Topper (oz4818) designs were Scotty Murray's most famous creations that used the single contour airfoil [Murray wing, aka Ritz wing]. Both were consistent contest winners, a fact he attrributed to the wing design. The climbing ability of these designs was a vast improvement.

The glide however was truly spectacular, with the slow gliding speed and low sink rate afforded by the single-contour wing. Even in still air on a cloudy day, Scotty's Answer kept circling in slow, lazy circles over Long Island long after the conventional design had landed.

Murray's designs became famous during his lifetime and he soon needed an inked drawing of his Topper/Answer design, but could find no ink draftsman among his buddies until I volunteered to do the job. As the youngest member of the group, I considered it an honour to prepare the drawing for this modelling great. After serving its purpose, the drawing was returned to me and I still have it as a prized possession, although tattered and moldy.

This 1938 antique drawing has been cleaned up and is presented here [see article pages, pp2] as a curio for the benefit of the modeller interested in antiques. A new drawing has also been prepared and is presented here, much amplified in scope for those interested in building Scotty Murray's Topper/Answer."

The Answer design was also the basis for the Keil Kraft Scorpion (oz5785) model, which used more conventional construction on the wing.

Update 14/06/2017: Have re-titled this plan now as the "Answer" thanks to Ray. The heading text on the plan saying "Scorpion" seems to be a later addition, done in error.

Update 16/06/2017: Added article, thanks to RFJ.

Update 16/06/2017: Replaced this plan with a much clearer version, thanks to Circlip.

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

Great scan, thanks. Nice to be able to see the detail on this plan, now.

Thank you so much for the upload of the Article featuring the "Answer". There is however a "Part 2" to this article that appeared in MAN the following month. Is it possible that someone might have this second part to the article? I think the "Answer" was one of the best flying Vintage FF IC Cabin planes I have ever had the privilege to fly (with RC assist).

We've heard from a reliable source that "part 2" of the Answer article is actually a plan and construction article for a different design which also used the Ritz wing and is called Hell Razor. We hope to be able to add the plan and article for this model to OZ in due course.

* 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.
