About this Plan

Crusader II . Radio control sport canard pusher model, for .40 power.

Quote: "For full barnstorming performance, try this Crusader II. It has lots of control power in most any attitude. Crusader II by Steven J Ellzey.

Leave an aerospace engineer alone with enough balsa wood in a warm dry place long enough and strange things are likely to come out, or at least that seemed to be the opinion of most people at the flying field when the Crusader II first showed up. To date, it has been called everything from an Air-Florida Concord to a violation of the ABM Treaty. In reality, it is just a good flying sport airplane that looks just a little bit different. Okay, it looks a whole lot different - however, it is a good flier.

The Crusader II was designed to be a very maneuverable airplane with good stability. The combination of the coupled canard and elevens, a fairly light wing loading, and the vortex generating system gives the Crusader II lots of control power in almost any attitude you can put it in. This allows for a bit of freewheeling abandon while flying. Since the airplane has a fairly light wing loading, low speed flight is very smooth and landings can be very easy.

All of my prototypes used a tuned pipe which runs through the nacelle on the bottom of the fuselage. The pipe is not really needed since the plane is light enough to fly wellwithout it. But if you want the full barnstorming performance the Crusader II can deliver, go with a pipe. You may need to modify the nacelle to accomodate the size of your exhaust system. If your pipe is larger than the one I used, you may need to make the nacelle larger.

If you have never used retracts before, now is a good time to start. Since the wing is built in one piece, it is very easy to install the main gears and hook them up. Since the top of the fuselage is removable, the nosegear installation is a snap..."

* 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.
