hi, as there are some more pilots who want to know why, we made an "official" statement to explain the reduced aspect ratio and
reduced cell numbers:
"In short words: it is simply not necessary to carry the higher aspect ratio when you find performance elsewhere.....
cheers, Manfred
There are 5 years of development know-how between the ARAK2 and the ARAK1. We used this experience and thoroughly optimized the ARAK2 with finely tuned trim, modified brake geometry, new materials and a slightly reduced aspect ratio. As a result of this development, the performance of the glider increased even though we reduced the cells.
Reducing the number of cells results in lowered weight of the glider an pack size. In addition, general handling becomes easier and despite an overall increase in performance compared to its predecessor, starting behavior improves.
In addition to the developments already mentioned, a performance-oriented trimming has been implemented in the ARAK2. This results in a more dynamic flight behavior, rapid response to control inputs, and increased agility. Therefore, the ARAK2 is designed to be an impressive mid-B wing suitable for ambitious pilots."
