About this Plan
Fly-By. Sport model for .35 power and full-house radio control.
Quote: "Hi Steve, the next plan is a fun airplane appeared in an RCM publication called RC Limited, in 1968. It was a one time magazine. The airplane was called Fly By"
Quote: "Approximately a year ago a friend of mine asked me to help him with the construction drawings of a scale airplane which he wanted to build. He spent many hours with the design and now and then I helped him. Although he has not yet built his plane, the experience I gained was well worth the time I spent working him. It was about this same time my wife said to me: You have been Ipir-z everyone build airplanes. Why not design and build your own? So, thanks to my wife, the Fly-By was born. Out came all my old drawings, and about week later I had finished the outline of the mode,.
I wanted a small ship, but big enough most equipment. I had a few other considerations too. Due to unavoidable circumstances, I needed a ship that was small enough to fit into the trunk of my car. You see, the rest of the car contains two children, one wife, and one dog. I also wanted an economical airplane (a friend said I shouldn't use the word 'cheap').
This was to be a good, full-house Sunday flier. Using a small engine such as a .35 would insure more nights per gallon, too. I now had all my ideas - the next step was to combine them into one ideal ship.
The Fly-By is small, having only a fifty-one inch wing span. With a .35 en-gine the ship moves along smoothly even at 5%. pounds. I am using the Digitrio 4, with Orbit type servos. By the way, this is just about the fastest servo I've seen. It makes the Fly-By very responsive, especially on ailerons.
The Fly-By has proven to be a very strong ship, Although it is an easy ship to build, the fuselage does require special construction. You will notice that there is no hatch in the battery compartment. This is because I feel it would weaken the front end.
One word of advice before you begin construction. Don't begin to cut any wood until you have laid out all the parts to be cut from the same stock sheet of balsa. Many parts of the ship are cut from a single piece of stock balsa. This is the feature that makes this ship inexpensive to build. I will explain further in the construction details exactly what parts are to be made from the leftovers.
Here are a few of the design features:
1. Three inch inside body dimension for most equipment.
2. Strip ailerons for ease of construction.
3. Standard size wood.
4. Splice at the tail end of the body. This will give you a 42 in body from 36 in stock wood. Don't let that splice fool you - it's strong!
5. A semi-symmetrical sixteen percent airfoil for good lift.
6. Sheet fin, rudder, and elevator.
7. Light weight sandwich type stabilizer.
All right, let's get started with the construction. Cut the sides from 1/8 x 4 x x 36 inch sheet. (See photo #1,) Before you cut the doubler, lay out both sides of the doubler with the front of the doubler in the center of the sheet. This will enable you to get two side doublers from one piece..."

* 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.
