About this Plan

This plan file includes a text article with some history...The D.Q.A. 704 was designed in the Summer of 1964 by Stu Babcock as a test bed for Babcock Controls new BC-21 and BC-22 single channel systems ...we were not only thoroughly convinced that Babcock's new single channel escapement and proportional systems were ideally suited for the sport flier and newcomer to radio control, but that the ship used as a test bed was one of the best flying, small-field single channel airplanes we had run across.

Corrections?

Did we get something wrong with this plan? That happens sometimes. Help us make a correction

DQA photos [see more pics 003, 004]. Came in at 9 7/8 oz but tail heavy. With nose weights should hit the design weight of 11 oz. Would recommend extending the nose a 1/2" or so for more battery room and for balance. The fuselage is short compared to the wing span.

D.Q.A. 704 stands for Damn Quick Airplane, and the 704 is how much it cost to build, not counting engine and radio. Mine was covered in red silk for the wing and jap tissue everywhere else. It's one of the original "park flyers" because that's where I flew mine. Nobody complained about the shriek from the Cox Pee Wee 020. I used the exact same Controlaire Mule transmitter shown in the photo, with a Citizenship "sugar cube" receiver and escapement. It needs every bit of the seemingly excessive downthrust for the Pee Wee, which was a little too much motor. Nowadays it would make a fine electric with about a 300 motor, and I would leave the landing gear off and skid it to a stop on the grass.

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.
