Parts and Construction

Parts and Instructions
This model contains 365 parts (pictured).  Most are standard plates and a few bricks.  At upper left are the Technic beams and the axles and gears have also been separated.  Of special note is that there are twelve 16L beams in this model.

My instructions from 1977 were printed in poster form.  The main instructions are one big foldout sheet with 13 steps, and the alternate model instructions are another sheet which also shows "blueprints" of the main model.  There are no parts lists for each step like you would expect from Technic.  Later editions of this set would have a conventional instruction booklet with individual step parts lists.   There are also photos of how to motorize both the main and alternate models with the optional 4.5V 870 Motor.

Like all Expert Builder sets, this model also came with a booklet showing many ideas of how to make alternate models by combining the parts of this set with other sets
The following images show the construction at intermediate stages.  Construction follows a reasonably simple bottom-to-top method with succesive layers of bricks and plates.  The control linkage prevents the model from sitting on a flat surface during construction which makes some steps quite difficult.

Alternate Model(s)

The alternate model is a huge airplane.  In most cases, there are very few, if any, parts left over from the main model and therefore the alternate model uses the same parts.  In this case, none of the four huge 6x16 plates used for the wings are used in the normal model, so they are simply extra unless you build the airplane.

This airplane features a gear system which ties the landing gear to the two blade propellor.   The gear is raked forward at an angle and the wings have diagonal struts for support.  The horizontal stabilizer looks a little small.
