The
first of the famous multi-role biplane line. It differed from successors by
thick (14%) wing to provide maximum lift at low speed - and absolutely
disappointing performance. Aircraft was made extremely robust (17g
for case Ak) and easy to assemble, but on expense of bad airdynamic
and more than 120kg overweight.
Aircraft had very bad climb even for primary trainer. It may
be remembered as an example of extremities in design, when too much is paid for
reliability and simplicity.
