About this Plan
Spitfire. Stunt CL model by Charles Mackey.
Quote: "Aerobatic Spitfire, by Charles Mackey. American Modeler, February 1960.
No matter how pleasing to the eye a control line stunt plane may be, it is not worth its weight in corncobs unless it is a good flier. This model was designed to be a stuntship first and a Spitfire second. We've considered this design for several years but never had time to work out all the problems as the Spitfire appearance at first did not fit itself to conventional stunt dimensions. Then some of our latest XP designs had proven to us that the extra long tail moment is a definite improvement. With the longer dimensions with which to work, the Spitfire worked out to a very scale-like appearance.
We also threw in a few other ideas that have proven themselves on previous designs thus hoping to eliminate any bounce or wobble on the 5' radii which the AMA pattern specifies. We are satisfied that our efforts were not in vain. Ronnie Peterson describes it as the best stuntship he has ever flown and says it flies as though you had hold of the wingtip drawing out the maneuvers.
The extra long tail makes it necessary to use lighter construction and softer wood on everything behind the CG. And then we still had to add 34-ounce, weight to the nose for proper balance. Check the plans carefully and note that the inside wing is 2 inches longer. This is achieved by omitting rib #1 from the outside wing. The spars will not match up in the center.
Cut ribs from soft 1/16 sheet balsa. Glue 1/8 sq trailing edge to bottom 1/16 sheet TE. Cut 1/4 sq leading edges to length. Turn on end and pin to plan - exaggerating the curve of the leading edge slightly. Pin the right side directly in front and run a bead of glue down the inside edges to help hold the curve and avoid wing from warping later. Cut the 3/16 sq spars to length and mark wing rib position with pencil. Pin bottom half of TE to ribs, insert 3/16 sq spars and pin into position. You might use masking or cellophane tape to pull the spars together at the tips. Glue the bottom half of the TE then add top half of TE. Cut two 1/16 sheet wingtips and four 1/16 sheet curved TE pieces. Align and glue.
When dry, pin the TE to flat surface or turn end ways and pin to table. Put 1/4 sq LE into position. You may find it necessary to use tape again. Glue 3/16 sq spars and LE and allow to dry. Bend landing gear from 1/8 dia wire. Note that the wheels are toed in slightly on the Spitfire. Cut the wheel mounts from hard 1/8 ply. Note the notched positions vary because the left side fits against wing rib #3 and the right side fits against wing rib #4. Mount the landing gear on firmly with J bolts and glue into position. Cut out center ribs for bellcrank and bell-crank platform. Cut and install the
Be especially sure to add bellcrank platform braces as plans show. Add 1/16 vertical sheeting in front and be-hind 3/16 sq spars as plans show. Notch out the center wing ribs for 1/8 sheet brace that fits the top and bottom of wing center section. Install 3 inch bell-crank, 2 pushrods and the leadouts. Be sure to slip on 1/8 dia tubing before bending leadouts..."

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

ScaleType: This (oz3678) 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 https://en.wikipedia.org/wiki/Supermarine_Spitfire
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.
Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

User commentsHello, Just to correct your information and picture that you have on the Charlie Mackey CL Stunt Spitfire . The person holding the stunt Mackey design Spitfire in your picture and on the front of the magazine that had the plans is is Not Charlie Mackey it is Ron Peterson and it is also Ron’s spitfire that he built from Charlie’s plans. Charlie Mackey and I were good friends in Indianapolis, In and he helped me get started in stunt contests at that time. Just to set the record straight,

Can you please tell me if the Charlie Mackey mentioned in this post ever owned a tavern in Indianapolis? Thank you!

* 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.
