Here is a picture of a picture of my Cheap Thrill 1/2A stunt airplane published in Model Aviation, December 1998. Plans available from AMA.

Very cute, Jim. Looks kinda like a teeny, tiny T-Bird . . .
-
It really is nice! Can you, describe a few details?
I would like to know about th efuse construction.

cool! How about size, weight, power. I fear I don't keep that magazine that far back. Now if it was Flying Models..... y1

I've always loved the look of elliptical wings. Just hate the geometry of it, and respectively unique ribs. Foam to the rescue!
-
Jim, that is a nice looking plane.
I went on the AMA archives and read the article. I like the 4" bellcrank. Do you still have the version with the built-up tail section?
I tend to build a little heavy so I would probably opt for the Tee Dee .09, or at least an .06.

As George said, the article is available on the AMA website. The fuselage was built in two pieces because the wing is so thick. The wing was built, covered, etc. and the front end glued on, then the rear end. the top was either sheeted or planked. Today, I would mold a top. The plans were drawn by Frank Beatty and are a work of art.
The first one was crashed due to a line break. The wing and flaps survived (suggests that the wing is overbuilt). I still have the second one. Unfortunately, I painted it with unplasticized Aerogloss and it needs a complete recover job. Wingspan is 36 in, weight around 11 -12 oz. TD 049 on pressure. Flew it on 42 ft 008 lines. I don't fly hourglasses very well, but I flew a 40-pointer with the first airplane. Of course, I was alone at the field at the time.

I downloaded your article. Most bodacious, dude! n~ You know, Eric Rule might be interested in kitting this puppy. With laser cutting, the varied ribs are NO problem. Tell him I sent you. =)

If Eric does the kit I will have to get on the list. That is one cute little 1/2A. DOC Holliday

I'd buy a kit of that. Looks almost supermarine like. would be a real spitfire in my book.
pun intended.
-
like to have in a kit also!
-
That would look really cool done up as a WWII Spitfire!
-
It has more or less a P-40 tail. Change the tail shape and it would be pretty Spitfire like. If you blew it up 1 1/3 you would have a 48 in span airplane about right for a modern 25 or a Fox 35. 1 1/2 would give 54 in span for a 40 or 46. Do a little revamping on the nose to fit the engine and get the CG in the right place, web the spars and maybe change a few wood thicknesses.

as a non-ama member can I download the article to read or do I need to be a member first... having trouble finding it.

Sorry, it is in the "Members Only" section.
That alone allmost makes the Membership fee acceptable.

See if I can bump this up.

Hi Jim,
After a bit of a marathon, I finally got the plans. I built it pretty light, just over 10oz and it flies far better than I can. Wasp 0.61 for powera 45 feet lines and just enjoy!

This is a fuzzy photo of a photo of the second in the series leading to the Cheap Thrill. The first one was similar to this one. I flew both those airplanes in a number of 1/2A stunt contests. I don't have a picture of #3, but still have my pencil plans. It is, appropriately intermediate in appearance between #2 and the Cheap Thrill. It flew very well, but I don't recall if I ever competed with it.
