Mini Atlas. RC pattern plane, for .40 power. This is a reduced-size version of the classic Wolfgang Matt Atlas (oz5517) .60 design.
Quote: "FOR some time I have been building .60 powered acrobatic models and living with their large size, transport difficulties and the general high running expenses of a performance model. The modern generation of Schnuerle-ported high performance .40 cu in engines however, make it quite possible to obtain really good acrobatic performance with a more manageable size of model and RCME has already published plans for several to prove the point.
With these points in mind. Wolfgang Matt's World Championship winning Atlas (oz5517) design was immediately the aeroplane I wanted to reproduce as a basis of my own venture into .40 acrobatic machines. Even allowing for the lighter weight of .40 engines and the fact that such motors offer outputs as high as a two year old .60 the original size aeroplane would be too big and complicated to construct and in any case, a smaller size airframe was half the exercise. Therefore I scaled down the outlines and preserved the sections and moments to produce a 'Mini Atlas', naturally with due acknowledgement to Wolfgang Mart.
Fuselage. The construction of the fuselage is straightforward and should present no problems for the average modeller. The basic procedure is set out below. Cut two identical fuselage sides by taping together two sheets of 3/16 x 4 x 36 in medium balsa. Mark the position of the 0.8mm ply doublers onto the fuselage sides, making sure of producing one left and one right hand side. Bond the doublers to the sides using contact adhesive. When PVA glue the four pieces of 1/2 in triangular section on to the fuselage sides, followed by F2, epoxy glued into position square to the fuselage side..."

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.
