An Experimental Machine

In order to determine whether the tandem-wing arrangement, as employed with the "Flying Flea," possessed the many advantages claimed and largely borne out by theory, Luton Aircraft Ltd., built an experimental machine having two wings in tandem but with an orthodox tail unit and normal controls, and this was subject to flight trials lasting over a period of some two months. 

None of the vices which characterise the "Flying Flea" showed itself, but a certain amount of mutual interference took place between the wings at certain flight attitudes, noticeably in the climb, which reduced the aerodynamic efficiency to an undesirable extent. 

The experiment had proved that if a light aeroplane was to be produced for the novice pilot and at a price that could be afforded by the many interested amateurs, it must be designed along orthodox lines, provided with effective but gentle acting and well synchronised controls, essentially stable in flight and on the glide, and with simple take-off and landing qualities so that the aeroplane practically performs these manoeuvres of its own accord. 

(Then followed) the development of one of the Newest and most Successful light aeroplanes, the Luton Minor.  Manufacturing costs must be reduced, not by eliminating one or more of the essential surfaces, but by simplicity of construction throughout and by the generous employment of building jigs.
