For the development of the glattCAD D.H. 88 Comet, a number of important parameters were analyzed and determined by software. They were incorporated in the construction. The Reynolds effect was counteracted with the implementation of a moderatet wist from the root ribs towards the tips at the expense of aerobatic capability. Fow slow loops, this causes the glattCAD Comet to fall out of the figure at the apex.

This can also happen during inverted flight. That these maneuvers do not really want to succeed is the price paid for more aileron effectiveness and safety. You can live with that, because the original Comet was not intended for such maneuvers either. In order to improve the dynamic stability around the z-axis, the tail surfaces have been slightly enlarged to improve the chance to react on an engine failure (combustion engine).

The theory´s correctness has been confirmed in practice with excellent results !
