About this Plan
Wayfarer - RC sport biplane model, for .40 power.
Quote: "One of the finest bipe's you'll ever fly - performs all the maneouvers in a realistic manner. Outstanding slow speed characteristics. Realistic performing sport biplane for .40 to .60 engines, by Don Dewey.
During the 1965 RCM Design Contest, we received a set of plans from a Dr DJ Gerner for a model that was later destined to become one of the all time favorites ever presented by RCM. Before presenting it for publication in the May 1966 issue, we constructed a prototype from the author's plans and virtually flew the pants off of it. This model was the Hobo (oz7166) a quickly built and easy-to-fly sport biplane for reeds or 3 channels of the new proportional systems.
The Hobo was an almost immediate success. It was a fun-type biplane that was extremely easy to fly, yet was rugged enough to withstand any type of rough field takeoffs and landings. Its slow speed characteristics were virtually phenomenal and it could be landed at a speed far slower than the normal stalling speed of most aircraft of its type. During the next two or three years, we wore out one Hobo and built at least two more, all of which were flown for many, many hours. All of the original Hobo prototypes required no takeoff corrections at all, and after exploring the sky at your leisure with a stable and easy to fly biplane and, as the author put it, "when you got tired of chasing the wind and playing tag with the birds, you could throttle back and come in for an effortless landing that would make the hot shots envious."
As proportional systems became more and more reliable, not to mention smaller and lighter in weight, we used the Hobo as a test bed for each of the new systems that came our way. The original prototype by the author weighed six pounds plus with the older and larger systems and, as the micro miniature proportional system became available to us, the weight of the plane lessened and we noticed an even greater increase in its performance characteristics. After a couple of years of flying with various radio systems, I decided to use the original Hobo's unique construction features in a new design that would retain its excellent handling capabilities and low speed characteristics while increasing its performance with the addition of ailerons and a reduction in the overall weight.
Thus, the Wayfarer was born. This model proved to be even more than we had anticipated when I started sketching the plans. In fact, the prototype is one of the best flying sport biplanes that we have seen at RCM. With 800 sq inches of wing area and an all-up weight of five pounds with the Kraft Series Seventy-One proportional system, it excels in the performance category with anything from a .40 to .60 engine. We used an OS Max H.40P engine on the prototype and found the airplane capable of all standard maneuvers while retaining the original and exceptional slow speed characteristics.
The overall wing loading is in the 15 to 16 ounce per square foot range which added considerably to those slow speed characteristics. Yet, under full power, the Wayfarer will climb out with the best of them and perform virtually all of the vertical maneuvers with ease..."

Article pages, text and pics, thanks to theshadow. Also previous scan version.
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsMy best friend and I built these as per plan, the horizontal stab failed on each of them. We beefed them up and they flew great!

Wayfarer Photos [more pics 005-012]. This plane was constructed per the RCM plans with the exception of adding electric propulsion and a nose similar to the Acro-Star (oz6256). I installed a NTM 4248-650KV motor, 60AMP ESC, 4-cell LIPO (3300mah), and a 14x7APC prop. Flies great with this setup. In order to allow the greatest amount of battery movement to balance the plane, I moved the elevator and rudder servos to the rear. This worked out fine. Thank you for hosting this wonderful site.

* 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.
