I thought there were way more gyros than in years past. Off the top of my head I think there were three, maybe four, Autogyro vendors alone. Magni had a tent for the first time this year plus their activities at the Ultralights area, and ELA, Sportcopter, and Silverlight were there as well. Didn’t see Titanium there, but maybe I missed them. Even Rotorvox had a presence.
The “warbird gyro” is a Pitcairn P-39, owned by EAA. Didn’t see it fly, though.
