I've always liked biplanes, and particularly admire those by WACO. Years ago I designed and built a glow-powered model of the UPF-7. I flew it for many years and thought it was one of the best-flying models I had designed. The WACO 10 is somewhat simpler in design, with nearly identical straight wings and a truss-design fuselage. This electric-powered version also flies well and is relatively easy to build.

As for the construction, the top and bottom wings are nearly identical; they have the same ribs, spares, center sheeting, and wingtips. However, the psan of the bottom wing is slightly shorter than that of the top; the bottom has 2 1/2 degrees of dihedral and ailerons; the top wing as no dihedral. Begin by making the 28....

On the flying field I see so many jets and helicopters, it's great to see beautiful biplanes like this getting coverage. These classics are great to fly!

First let me say I am happy to be able to view current Model Aviation articles on line and then read up to date comments by modelers.

I have a Waco 10 kit in my shop that I have been sitting on for at least 15 years...maybe I will get it out and work on it now!

I prefer biplanes and that turns out to be a great thing because so does my wife. If I bring home or build a new monoplane or helicopter she will likely say, "nice, did you need that, don't you have one like that, or where are you going to put this one?" But if I bring home even the homeliest biplane she will generally say, "What a nice bipe, I like it!" So I keep bringing them home.

Yes. I saw many times that Film, in my life, but the wifes are Beatifull always.... the mine her name was SUSANA died in the 2010.

Good morning: My name is Gordon and I am by nature a polymath(likes to do many different things), and I am working on a prototype of an aircraft that I will try my hand at building this Spring/Summer. I am a newbie to this Association, and wish to say how impressed I am from what I have seen and read. Simply astonishing...simply....astonishing. I think everyone en mass should take a bow. Best regards, Gordon
