About this Plan

Genesis. Radio control sport model. Wingspan 41 in, for OS 10 power and 2 channels.

Quote: "You've just got time to build this sleek sports model to slip into the back of the car for those summer picnics. 41 in span for 2 functionR/C systems & 0.9-15 motors. Genesis, by David Brand.

WHILE suffering from a recent illness I had this vision of Bill Burkinshaw attired like an avenging angel demanding a reason for not supplying him with an aircraft for publication before it was too late (RCM&E always gets their plan). After this vision had extracted a design promise from me, my health improved rapidly so I was obliged to put pencil to paper immediately on convalescing.

Having marvelled at the performance of acrobatic slope soarers operating off pure lift I decided that it must be possible to design similar lightly loaded and very clean aerobatic aircraft for small engines. One drawing pad, three 1/2 scale balsa silhouettes and two full size cardboard cut-outs later, Genesis was born. Why Genesis? Because in an enthusiastic moment I thought it would be the first of many.

May I point out to anybody who might be a little concerned by its sleek lines, that this is an easy aircraft to fly. It is extremely smooth and positive without being oversensitive.

By using the usual expedient of varying the ratio of wing depth to chord over its span Genesis has very good low speed characteristics.

Finally the weight of the prototype with 280mA Ni-Cads and two channels from my MacGregor Digimac IV came to 1 lb 15 oz, achieved quite easily by using good quality medium and soft balsa wood, contact adhesive and balsa cement.

Fuselage construction: Cut the fuselage sides and the centre section doublers from medium 3/32 balsa sheet. Mark out and cut the fuselage doublers from 1mm ply, glue these parts together using contact adhesive making up left and right fuselage sides. Attach the 1/2 in and 1/4 in triangular longerons to the sides using balsa cement.

Cut the formers 1 to 4 from 1/8 ply. Join the fuselage sides with F2, F3 and F4, when thoroughly dry, draw the rear together and glue a piece of 1/4 x 1/8 tail spacer between the ends. Draw the front together and glue F1. Bolt the engine mount to F1 using 6BA bolts and blind nuts. Temporarily attach the engine to the mount in order to assist in aligning and fitting the fuel tank. Attach the servo rails and servos. Please note that the elevator servo is mounted on the left side of the fuselage in order to make room for the aileron servo attached to the right side of the wing centre section.

A small combined elevator joiner and control horn is used for the elevators. I used the Veco type. The control horn is positioned inside the fuselage. Cut out the horizontal stabiliser and elevators from 1/8 medium balsa sheet..."

Quote: "Hello. In 1979, as a teenager, I built this model but never flew it, and, what is worse, I can't even remember what happened to it. So, I really wanted to build it again and have been searching for it for over 30 years! Nostalgia is a slippery slope! Some weeks ago, I saw the plan being auctioned on EBAY, and I bid on it feverishly. I won the auction, and a couple of days ago it showed up in my post box! I would like to share it with everyone, and thereby save it for posterity! I scanned it at 600 dpi. Keep up the good work! Regards, Howard"

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.
