• 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
