Rh Bevel off the under side of the front edge of both planes. Fasten the planes to the spine with rubber string, rubber bands will do, this will allow easy adjustment back and forth on the spine. There are many experiments that can be tried with this model. Move the foreplane back, try; move back plane foreward, try; move foreplane foreward, try, and so on. This model and all other models are just the opposite of teeter boards. If too much pressure comes at one end, up it goes, if too much at the other, up that end goes, while the same thing applied to the teeter, that end goes down. It then seems clear at the start that we must have balance fore and aft, as well as right and left, with the kite we must balance right and left, but if the up and down does not quite tally we can counteract by adjustment of the bridle, but on gliders and model aeroplanes, there are no bridles. The little ship must go "all by its lonely".

Another adjustment is possible, and probably will be necessary, and that is tipping of the planes. By the use of little wedges, the front
