I had a chance to see the Dynaero MCR-01 yesterday at Malmi airport. Here are some interesting pictures about it:
Double slotted flaps:
Interesting finding: the upper slot is rigid part of the flap. It does not move by itself, and the mechanism is as simple as on plain flap or the single slotted flap found on Cirrus or Diamond. When the flap is retracted, the slot hides under the wing. Very clever design.
