Frankenstein (oz1510)

About this Plan

Frankenstein. Free flight cabin power model, for 1 to 1.5cc motors. From Aeromodeller, December 1949.

Quote: "A strong, easy to build, pleasing looking sport free-flight model. Designed for the Mills 1.3 and motors of similar capacity, it is very simple to trim and puts up consistently steady flights of three mins, on a 40 sec motor run. Due to the light wing loading, the model is partial to thermals and resultant excitement has been experienced. It is crash-free to date, save for one spin. which did no damage. No contests have been entered as the designer's district has a dearth of clubs, and in any case Frankenstein is a sport model rather than a contest design.

Fuselage. The nucleus of the fuselage is the part consisting of the two ply formers and the engine bearers and it is essential that this should be strongly made and perfectly true. The first thing to make is the former which carries the undercart fixing. Having cut out the wooden part bend a strip of dural to the shape shown on the plan, place it in position on the former, then drill two parallel straight lines ofsmall holes through both the metal and the wood. Cut a piece of 14G brass tube to the width of the former and place it in between the lines of holes on the opposite side to the dural plate. Now sew the whole thing together with wire and drill holes in the dural opposite the ends of brass tube.

The front formers and engine bearers are then made and the 'nucleus' is assembled carefully with good glue. Next build the fuselage sides on the plan from balsa strip and cement them on to the formers. The cross members are inserted and construction finished off by adding gussets, celluloid, side cowling of sheet of balsa, tailskid and sheeting, etc. Cover with Burmese tissue.

Wings. Build up the two wings one at a time on the plan com- mencing with two main-spars, then leading and trailing edges and finally the subsidiary spars. The two wings are now fitted together with gussets and 5 ply dihedral braces, two on each side of the top and bottom main spars and one at the trailing edge spar..."
