About this Plan
Renate. Radio control aerobatic model. Wingspan 44-1/2 in, for .20 four strokes and four functions.
Quote: "JOHN BRICKELL describes his 441/2 inch span aerobatic model for four function radio and .20 four strokes.
This model was developed after visiting a very cold and windy Southern Gala, where the only aircraft that turned my head was a small own design model powered by an OS FS-20. Although a bit boxy for my liking, this model led me to one alternative, if a small aerobatic model was really what I was looking for, I would have to design and build my own. After a fair bit of drawing board bashing, Renate was designed. The following is a procedural guide for those of you who wish to build and fly Renate.
It is always best to start with a kit of parts, this allow all cutting to be completed and leaves a clear bench on which to start construction. After gluing formers 2C and B together, construction proper can begin by fitting the engine bearer to F1. If blind nuts are being used lay the fuselage with doubler uppermost on the workbench then glue F1, top tank bay decking and F2 to the fuselage, making sure that F2B and C fit into the appropriate slot. Check finally that F1 is square to all the other surfaces.
The servo deck is next to be fitted, followed by F3 and F1b and the lower tank deck. When all this is dry, glue fuselage side number two into place, check that all is square and leave to dry. Assuming that everything is OK so far the tail end of the fuselage can now be glued together.
The front decking is cut from 0.4mm ply, fitted dry and held in place using masking tape, this is done so that the fuselage sides together with the position of F1 and F2 can be marked in. After shaping, glue the front decking in place using contact adhesive. Be careful not to spread the adhesive where it isn't needed, it is very hard to sand off. Finally, add both of the balsa stiffeners between F2A and F3.
The tailplane can now be added along with F3, 4, 5, 6, making sure these are all true and in line. Trial fit the ply decking marking F3A and F6 and fuselage sides. When cutting the decking, leave extra on the front, allowing this to be sanded level with F3A. Rear decking is fixed with contact adhesive as the front.
The fin is now glued in place and the rear decking tack glued to it using cyano and fillets made to suit. The tail wheel is then made up and fixed to F7. Bottom tank bay is next, followed by fuselage bottom grain, crosswise of course.
Cowling and Canopy: With the engine in place and the prop and spinner fitted, tape C3 to the spinner with a 1/8 in spacer in between. Glue the cowl sides between C3 and F1 and then glue C1 to the sides. Fill in the scrap balsa, screw C2 to C1, fit C4 and glue balsa sides in place, fill the rest of the spaces with scrap balsa..."

* 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.
