Quote: "The Middy Duration model, designed by JS Evans. THIS small model was officially tested by the Aeromodeller Staff - which means a great deal! Even after the ministrations of this body, whose tender feelings where models are concerned have long since atrophied, the 'Middy' came through all the strenuous tests with flying colours, having proved itself virtually crashproof.

The model was tested on four strands of 1/4 in x 1/30 in rubber, and on average turns clocked a regular 45 secs. The amazing thing about this model when trimmed for right-hand circular flight, is the way it consistently makes three circuits, then glides in very flatly to a point seldom more than 20 ft from the launcher - a great boon to one's poor old feet.

The model flies very well indeed on the four strands of rubber used, but the performance is considerably improved when powered with six. To sum up, the hallmarks of this niodel are simplicity, stability and consistency. We have no hesitation in recommending it to our readers as an excellent general purpose model, especially suitable for the beginner to the hobby, who wishes to build his first duration model.

Construction and Flying: The fuselage is built in the same manner as an ordinary slabsider, ie two sides are built on top of each other on the plan. Cut all cross-members first, four for each station. When the two sides have been built on the plan and the cement has set, they may be separated with a razor blade. It is best to put in the centre members first, using cardboard jigs or cardboard formers to preserve the shape; wait till the cement has set, then insert the remaining front and rear spacers, drawing each end of the fuselage together with rubber bands, using ode at each station as the cross-members are inserted.

The wings are constructed in the usual manner . a tracing should be taken of the port wing so that when reversed it will form the plan of the starboard wing. The rest of the construction follows conventional practice, the only point where great care is needed is with regard to the wire wing mounts which must be let in exactly as shown on the wing rib section in order to preserve correct incidence on both wings.

For normal flying in a small field, power with four strands 1/4 in by 1/30 in rubber, but for a really snappy climb six strands should be used. Trim for right-hand circular flight and flattest gliding angle in the usual manner, little or no downthnist should be required. If the plan is strictly adhered to no packing for incidence should be necessary; the dihedral angle may be increased if extra stability is needed on windy days by bending the wire wing mounts upwards."
