Miss Denver (oz8084)

About this Plan

Miss Denver. Radio control sport model for .60 power.

Quote: "I would like to introduce you to Miss Denver - a very welcome companion at a Class C stunt event or an open pylon race.

If you have already looked at the plans you will see that this is a plane that is made to look like a stunt flyer and not the latest military weapons system, or, on the other hand, some box with a wing attached. Miss Denver was designed to look like an airplane used in stunt events or sports flying while utilizing the latest and fastest method of construction possible consistent with keeping a trim weight of approximately six and a half pounds.

What? A standard landing gear? Whoever took a lady to a contest that had three legs? You will find out, after a few flights, that Miss 'D' will handle every bit as well as a tricycle geared plane with a lot less money spent on propellers. Also, if you would like to have the tricycle landing gear crowd hide their heads in the sand, install a set of electric brakes using right rudder - right brake; left rudder- left brake, up elevator - both brakes, using extreme throw of controls to actuate brakes.

Miss 'D' was designed to win Class C stunt events but has proved also that an open pylon race is fair game. She has never placed less than second place in any contest entered. In the Mile Hi RC Contest at Denver, Colorado she placed first in Class III stunt. This contest had very formidable competition with German Fighter pilots for judges. In Wichita, Kansas, she took first in Open Pylon; second, Class III stunt. At the Colorado Fall Festival, she won top honors in Open Pylon as well as Class III stunt.

Miss 'D' was not designed overnight. To the contrary, approximately fourteen months of modifications were made from the date of the original conception. Not being an aeronautical engineer, I did not take it upon myself to design the airfoil, but made several wings using semi-symmetrical, symmetrical, tapered, and straight wings, using contest-proven airfoils. The wing used was decided upon for the following reasons:

(1) Any improvement a taper could make was far outweighed by the case of building a straight wing.
(2) The airfoil had these advantages - (a) good rate of sink at low engine rpm; (b) very stable, all stalls are clean, with no snap characteristics at any speed; (c) smooth, even flight inverted or upright, no jerking or bouncing about; (d) good speed transition.

The wing-testing program was carried out with the help of Bill Kessler of BK Model Products, using foam wings manufactured at his shop.

You probably noticed there is a fiber-glass cowl. This is no harder to build than a normal balsa cowl and has the advantage of being stronger as well as making access to the engine very easy.

Miss 'D' uses a radial mounted engine. I feel this is a definite advantage to the builder for the following reasons:

(1) Ease of mounting engine
(2) Completely clean fuel and battery compartment
(3) Unequalled strength

But most important, every engine and every different size propeller demands a different right thrust setting. More good airframes have been set aside because they wouldn't track properly through loops, etc. This was not the fault of the aircraft, but simply required a small thrust change to correct..."
