Korda Dethermalizer (oz423)
About this Plan
Korda Dethermalizer. Wakefield model by Dick Korda, 1941. Korda of course had already won the earlier 1939 Wakefield competition with his previous rubber competition design see Wakefield Winner (oz5395).
Quote: "How do you improve on a Wakefiled Winner? You probably can't. After all, there are many factors besides the model's design that put it on the top. In Korda's case he, by design or luck, launched into one of the only two thermals to come through Bendix Airport New Jersey on August 6th 1939, and his famed model came down 43 minutes and 15 seconds later, wiping out all Wakefield competition on the very first official flight.
This model, which at 300 sq in is slightly larger than its famous predecessor, is also notable in another way. It was among the first to use a new-fangled gadget in competition that brought the model back to earth rather than allow it to fly away. It was nicknamed a 'dethermailzer' and the name has stuck ever since. Lacking a name for this new rubber ship which proved itself at the 1941 Nats, Dick Korda dubbed it the Dethermalizer.
This was before tip up stabs came along. The D/T on Kord's model put the ship in a steep enough spiral to bring it out of a thermal - maybe not the gentlest method, but it worked."

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

User commentsThe D/T is not the classic 1939 Wakefield winner but a larger follow on. It is considerably larger than 36 inches. Thank you.

I came across a little more on the Korda Dethermalizer. Span was 50 inches, area around 300 square inches. Published in 1942.

* 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.
