Stream has been designed on Stranger basis. The main purpose of creating a new wing was increase of maximum launch weight up to 450 kg, preserving at the same time Stranger's flight performance
Stream wing has as wide speed range, as the Stranger, note that the former's minimum speed is a bit lower (50 km/h for a single-seater variant). Controllability of this wing satisfies needs of an "average" pilot. It is not as control sensitive, as the Stranger, but predictable at any speed and forgives abrupt pitch control. Roll efforts are normal and allow easy changing of bank angle from 45° to 45°. Launch is without any peculiarities - after the take-off, while the wing has not acquired trimming speed, there is some slight reverse effort on the control bar, which can be balanced, if necessary. After the take-off the wing is trimmed at cruising speed 80-85 km/h. Pitch effort at all speed range (from 50 to 110 km/h) have right gradient.
