About this Plan

Cobra. 81 in span snake-like gas free flight by Ted Patrolia, 1948.

Note there is confusion on spelling of the author's name - it is written on this plan in 3 different ways: Patrolia, Petrolia and Petralia.

Note this plan was not published in the model magazines. Although a photo of Ted Patrolia with his Cobra did appear in the 'Dope Can' column of Air Trails, December 1950. Previously we had this plan listed as from Air Trails.

For a short later article written by Ted Patrolia himself about the Cobra, published in SAM Speaks, March 2001, see http://www.thebuildingboard.com/2009/03/ted-petrolias-cobra.html

For scans of the original paper drawings by Ted himself, as posted on RCGroups by Happymcc, see https://www.rcgroups.com/forums/showpost.php?p=15950319&postcount=38. Most likely these original drawings were the source Planeman used to derive this main planfile listed here.

There are a couple of great threads on RCGroups with more details on this design - see Petrolia Cobra build by brokenspar and 1948 Cobra by Ted Petrolia by Happymcc.

Some photos of my Cobra [main pic, 005,006].

This Outerzone presentation of Ted Petrolia’s Cobra is in need of the following clarification: In the data file, the citing of Air Trails is for the photo of Ted and his Cobra that was published in Air Trails in December 1950 in the model news column called Dope Can. If you go looking for a feature article on Ted’s Cobra published in Air Trails, you’re not going to find it, because Air Trails did not publish a feature article on Ted’s Cobra. Am I right?

Let's assume you're right. If not, someone else will pipe up, I'm sure :) Ok I have removed Air Trails now from the datafile. Many thanks.

I don’t object to citing Air Trails in the data file. Actually, I think it’s appropriate. The Air Trails photo of Tom and his Cobra appears to be an all-important indispensable detail in the story of the journey of Tom’s Cobra plan to the Outerzone website.
In Sam Speaks, March/April 2001 issue, Tom writes:
“When my friend asked about the Cobra in 1997, I wondered if its picture in Air Trails (December 1950) would help with getting approval from the NFFS Nostalgia Committee. I took all of my documentations to them. Their stamp of approval was given last year. After all these years, the Cobra is flying again.”

Oops, I meant Ted, not Tom.

Um, no, for me the 'from' field of the datafile is only for publishers and/or kit makers. Essentially the company that produced the paper plan. Don't want to start using it to hold references to photo appearances. That way lies madness. Also 'from' is used in advanced searches. Have added the following text to the About section: "Note this plan was not published in the model magazines. Although a photo of Ted Patrolia with his Cobra did appear in the 'Dope Can' column of Air Trails, December 1950. Previously we had this plan listed as from Air Trails."

“Clarification”...mission accomplished. Thanks Steve. Your work and Outerzone is stellar.

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.
