JUNE 7, 1923 LIGHT 'PLANE Those wishing to get in touch with others interested in mattersrelating to gliding and the construction of gliders are invited to write to the Editor of FLIGHT, who will be pleased to pub'ishsuch communications on this page, in order to bring together those who would like to co-operate, either in forming glidingclubs or in private collaboration. THE Gnosspelius light 'plane, which was fully described inlast week's issue of FLIGHT, made further flights during theweek-end. After a few minor alterations suggested by the flights made during the previous week-end, the machine isnow considered to be ready for complete tests, and she will probably be sent to Martlesham, where special facilities exist intended to get as many accurate and reliable figures aspossible relating to speed, speed range, climb, manoeuvr- ability, etc. • • *, WITH reference to the design for " Turkey Buzzard," acorrespondent has written in to point out that it seems likely that trouble may arise owing to one or two details in thedesign which do not appear to have been sufficiently carefully considered. For instance, our correspondent thinks, and weare inclined to agree with him, that the J in. square diagonal spruce struts in the main plane and ailerons, which keep thetrailing edge cord taut, are not stiff enough to resist the fabric HHHHH H 0 13 13 13 H H H 13 13 13 H 13 m m 131313 E S S H S The L.F.G. gliderPhonix 3 : This machine is anengineless flying boat, and isstarted by being towed behind amotor boat.

At the same time the climb is good and the landing speed very low, while the controllability appears to be as good as can be desired. • • • AFTER a short delay the " Wren " designed by Mr. Manning,and built by the English Electric Company at Preston, is to be put through further tests by Squadron-Leader Maurice Wright.It seems probable that by the time this week's issue of FLIGHTis distributed further flights will have been made, although a good deal naturally depends upon the weather, as it is now tension and that of the cord. Reference to the wing drawings published in our issue of April 26 will show that these diagonal struts are to be lashed to the rib stiffeners, and that, conse- quently, their free length is nowhere very great. Neverthe- less, it would do no harm to make them a little stouter, just to make sure. * * * THE second criticism offered by our correspondent relatesto the end ribs in the ailerons and the adjacent edges of the main planes. On the drawings no indication is given that it isintended to make these different from the standard ribs. As our correspondent points out, there would not appear to bemuch point in making ribs which will stand a direct load of 264 lbs. if they are to be allowed to collapse under lateral Baron von Freyberg making a flight in the Harth-Messerschmidt glider, on the coast of the Baltic. ••-•" 303 ;; . ^ , c2
