Soares,
No preste ninguna atención a Stik. El Pitts es una avispa enojada. El Yak es un cisne! (apologies to all native speakers of that elegant language).
If yo uare very lucky perhaps SSD might be persuaded to send you the text of his article from Pilot about three years ago, in which he so splendidly captured the character of the Yak-52.
