The improvements over the ASH 25 are given as:
- a larger span
- new wing sections with a coefficient of lift that is about 0.2 higher[5]
- a maximum take-off weight of 850 kg for the Mi version
- automatic control surface connections for the entire aircraft
- enlarged cockpits
- larger canopies to improve visibility and to allow easier entry and exit for the rear pilot
Variants
- ASH 30
- The un-powered prototype glider.
