I first saw a picture of the Murphy Rebel in a copy of Pilot magazine (October 1994). The Rebel immediately struck me as a great subject for Peanut Scale. The clean lines and flyable proportions make it a winner in the sky, and the simple structure means you won't spend all winter at the building board.
Canada's Murphy Aircraft Company produces this aeroplane and a number of other types as kitplanes - so there's a wide range of personalized color schemes available to anyone who wants to check the aviation press. If you have Internet access, a good place to start is www.murphyair.com which is the company's official website. It contains a great photo gallery of their customers' projects.
Building the model is straightforward. But as usual, there are a few tricks of the trade that might be worth mentioning along the way. Most importantly, if you want to build an accurate replica of a real aeroplane, do some research first. Use the website or other references to pick a color scheme that you're attracted to. Before you begin, check these photos carefully for other differences. Rebels are available with a variety of engine mountings and cowl designs, alternative undercarriage types, and individual projects show differences in windows and other details. Purists will want to alter the plan before they start cutting wood to make sure they get the aeroplane they want. Having said this, I've started out with the fuselage more boxy than the real thing, so it's already a bit semi-scale!
Fuselage: Build two fuselage sides over each other. When dry, separate them with a razor blade and add the cross pieces to form the fuselage box structure. The undercarriage wire can be added at this stage. Bend some 1/32 sheet balsa pre-cut to the correct width to fit between the fuselage sides. Cyano this sandwich together. As this and the other cross pieces are glued in place, check that the fuselage remains as square as possible. When this is done, add the 1/2-inch sheet cowl sides to the top of the longerons. Top this off with 1/8 sheet as shown on the plan, making sure the grain runs across the fuselage. Rather than using formers and stringers, I chose to design the nose this way to give as much motor hook clearance as possible for downthrust adjustments.
Noseblock and prop: Cut a 'key' piece to fit inside the front of the fuselage and glue this to some soft block balsa. This unit and the top of the cowl can now be sanded to the correct shape. Install a Peck Polymers nose button after covering, but make sure to install it in the middle of the noseblock. If it is positioned too high, downthrust adjustments will bring the hook too close to the top of the inside of the cowl and cause the rubber to get caught up and stop the prop during flight.
Flying surfaces. The Rebel's square lines make the flying surfaces an easy task. Both tail surfaces have been enlarged slightly for added stability. I build in about 3/32 inch of washout in both wing surfaces by propping up the trailing edge wing tips while the glue sets. Do this again during the covering stage.
Covering. I use colored tissue to create my color schemes. It's worth studying the pictures you have and taking time to plan the best way to achieve the effect you want ahead of time. G-BUTK is a simple white tissue job with colored strips doped on later to finish the design. My model was lightly water shrunk and doped, but be careful of warps and weight!
Flying. My model tends to wander about a little, which makes it tricky indoors. Outdoors it looks great and it's getting better every time I add more downthrust. A design like this has great potential, so keep it square, keep it light, and be patient till you get it flying right!"

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 (oz12044) 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.
Notes:
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Murphy_Rebel
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.

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.
