About this Plan

Moonbeam 2. A 50in V-tailed slope soarer, published in RCM&E in July 1967.

Quote: "A simple 50 inch span R/C Slope Soarer with a vee tail, designed for pulse proportional or simple single channel with escapements. Moonbeam Two, by John Kay.

This is the second in the series of a simple single channel slope soarer, and using the suggested sequence of instructions the Moonbeam airframe can be completed in a weekend. A butterfly tail was chosen as it was felt to be the best way to obtain smooth flying using a single surface. The original model was flown with Derek Olley Fleet pulse proportional equipment using a double ended 'Adams' actuator operated by a transistor switcher. Ballast and batteries are provided by 4.8v 500 DKZ DEAC, and under normal flying condi-tions no additional ballast is necessary. Ready to fly, the Moonbeam should weigh between 20 and 25 oz.

Although the model was intended to be flown with pulse proportional actuators, such as the Adams or converted Mighty Midget, operating through a torque rod, there is adequate space to fit a normal escapement. For ease of construction the following tools are suggested:

24 in Steel Straight Edge.
6 in Engineers' Rule.
3 in Engineers' Set Square.
Zip Razor Plane.

Fuselage. Start by making sure that the edge to be worked from is straight. Mark out the fuselage and the position of all formers using a set square. When the sides are cut out, pin together and sand to ensure accuracy. Add braces, actuator rails and rear ply doublers using impact adhesive. Cut out all formers, drill and fit 18 gauge bush to former F5. Cut off surplus material and keep the remainder as it is used as a rear bearing in the fuselage. Join F5 and F6 together using impact adhesive, and Balsa Cement the formers F4 and F6 to one side of the fuselage.

While this is drying, cut out sheet for top and bottom of the fuselage. Join the fuselage sides together and check that top and bottom are square, and when dry add nose and tail blocks together with the remaining... "

Quote: "...my original met its demise among the heather in N Wales not, I might add, because of the way the model was designed but because of the way I built it ...I have taken the plan and have redrawn it in Auto-cad. I have sized it so that it matches the dimensions in the article but have not included the details of the isometric view of the tail nor the escapement installation. Apart from that it is per original. I am pleased to share the tracing with you here - enjoy."

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.
