8.
Unfortunately, as well as reducing adverse yaw, Frise ailerons will increase the overall drag of the aircraft much more than applying rudder correction.

F ( model or product F ) by the OKB ) because it offered the advantages of improved landing performance and better visibility from the Frise ailerons.
10.
Manually operated split trailing-edge flaps were fitted, and the controls surfaces consisted of differentially operated Frise ailerons which were mass balanced by lead strips within their leading edges.
