About this Plan

Swayback. Free flight power model featuring unusual 'elliptical dihedral' wing construction. Atwood .049 shown.

Quote: "If you want a Half-A free flight job that is out of the pylon rut, different from other high-thrust jobs, keep reading - you'll find that Swayback draws plenty of favorable comment from expert or beginner, the elliptical dihedral wing, vertically mounted engine timer and unusual dethermalizer setup getting the nod of approval from most. They will all approve the fast, straightaway, almost vertical climb and the flat floating glide. Besides the maximum flights and contest wins, you'll have the personal satisfaction of building and flying a sleeker looking airplane than the average bare-minimum, squared-off contest type. The first step in construction is the wing building jig. Look over the two shown in the drawing and decide which type you prefer. If you have access to a band or jigsaw, I suggest the solid type. The alternate type will do the job but requires more care in aligning. In either case, you will need to trace the wing dihedral curve, full size, on a piece of cardboard, carefully marking the centerline of the wing on the cardboard..."

Quote: "Hi Steve and Mary, This file was a struggle to come up with a decent scan. The original is red on gray and requiring about a 500% increase in size. I locked up my computer twice when working on this file. The full size drawing is a black and white TIF at 400 dpi which came from a light gray scale scan. Gene"

User comments

Hi, I am sending photos [main pic, 005-011] of the free flight model Swayback (oz8080). I recently got an RDT Timer BMK E36 + and wanted to build a regular E36 model. But in the end, I decided to use a historical model as a template, and after a long browsing of the Outerzone website, I discovered a beautiful and quite unusual Swayback model. Since I don't have a suitable internal combustion engine, I used a 24 gram brushless motor, a 15 A regulator, a 2s LiPol 300mAh to drive and everything is controlled by a BMK E36+ timer. Construction was not easy due to the unusual construction, but seeing this model in the air is really great. I'm sending more photos, choose what you see fit.. Best regards,

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.
