About this Plan

Dirty Birdy 40. Radio control pattern ship, for 40 power. Wingspan 58 in, wing area 565 sq in.

Quote: "The Dirty Birdy 40 is a new fun fly and pattern ship, designed by Joe Bridi in the image of the contest winning Dirty Birdy 60 (oz4915). Although the Dirty Birdy 40 really moves out with a hot .40 up front, it's a gentle and rock steady plane in flight. Response to the control surfaces is smooth. A minimum of surface deflection is all that's necessary for it to perform as you'd want it to. As a result, the plane is reliable and predictable; one you'll really enjoy flying.

Our building sequence begins with the fuselage. Because of the flat fuselage top block, the fuselage is built in typical Bridi fashion; upside down. Then the stab, elevator, fin and rudder are built. Finally, the wing panels are assembled, the wing halves joined..."

* 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.
