Horten Ho I - wood 1/144

Studies of the stability and controllability of flying wings would continue with our first sailplane. We were hoping to establish the center of lift on each wing half, and also to see if it was possible to steer the aircraft with wing tip drag rudders, instead of the traditional vertical fin-rudder arrangement.
 My brother and I was also hoping to improve our own piloting skills on the H I, as our total flying experience amounted to less than one hour in a primary glider.
 We planned a mean chord of at least one half meter, and a root chord large enough to accommodate the pilot This meant a wing with steep taper. A keel structure contained the seat, 10 cm below the bottom wing surface, and the canopy protruded 30 cm above. The root thickness was 60 cm, which, with a 20 % airfoil thickness resulted in a root chord of three meters.
The resulting triangular wing had an almost straight trailing edge, with two elevators in the center, flanked by two ailerons. The washout was 7 degrees, with most of the twist outside Y= 0.75 (the last quarter of the half span).
 The elevators were moved by pushrods, the ailerons by cables, all attached to a conventional stick. The rudder pedals were linked to drag rudders near the wing tips. They could be operated separately for directional control, or together as spoilers something that had not yet been introduced on other sailplanes. With no workshop available, and no financial support, it was necessary to build the aircraft in our home with personal funds.

I attach great importance to the statement that the symbols of the Nazi period ( Swastikas ) serve only a faithful reproduction of the models. A political attitude can and should not be derived from it. The generally applicable laws and regulations, which allow an exhibition of Nazi symbols, will therefore be satisfied.
