About this Plan
Boulton Paul Defiant. Radio control scale model. For Veco 61 engine. Wingspan 60in, area 590 sq ins. Stand-off scale WW II British fighter.
Quote: "Adding a gun turret doesn't make for an agile fighter, but it does make for an interesting .60-powered model. The Boulton-Paul Defiant, by Dan Reiss.
Be prepared to do a lot of explaining at the field with this aircraft. Not many people have heard of the 'Defiant,' much less ever seen one. If it wasn't for Profile 117, I probably would have missed this jewel too. What's so good about it? Well, as a full size aircraft it wasn't very successful. It was a British built airplane that the Germans used for target practice at the beginning of World War II. It wasn't meant to be that way. but that was the way it turned out. Since the Boulton-Paul factory was having trouble replacing them as fast as the Germans were shooting Defiants down, they were pulled from the front lines and relegated to less hazardous duties. You can get the full story in that Profile.
However, as an R/C model they're hard to beat. Their proportions are excellent, especially for a Stand-Off-Scale flyer like myself. So, with a set of plans in front of you and with the Profile as inspiration, clear off your work bench. You're going to enjoy building and flying this one.
Wing Assembly. Start with the wing first. Use the templates shown to cut the three foam sections required (one center section and two tip panels). Trim off the trailing edges and glue on strips of 1/4 by 1/2 in balsa. With masking tape on the foam to protect it, carve and sand the trailing edge to shape. Cut out the foam for the servo mount and the two aileron bellcrank mounts. Install the bellcranks on their mounts and epoxy them into the wing. Hook-up the aileron pushrods noting that the small one to the aileron crosses the dihedral joint.
Epoxy in the 1/8 in plywood rear wing dowel sup-port and servo mount. Temporarily install your servo and make up whatever linkage is necessary to get from the aileron push-rod to your servo. Using your radio, vary the servo from full left to full right to make sure that there is no binding. Remove the servo. Cut out an indentation in the foam to receive the 1/4 x 1-1/4 in aileron hinge support. This can be done by using a piece of #16 copper wire, bent to the proper shape, and inserted in your soldering gun..."

ScaleType: This (oz5449) 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/Boulton_Paul_Defiant
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.

* 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.
