RE: 28% Extra special
Be shocked.
The plane is both heavy at 20 lbs. and if balanced at the forward c/g location is nose heavy. Combine the two with excessive elevator deflection and a snappy plane is assured. I'll bet it also lands fast and has a steep power off glide angle.
The original 28% Extra Special should have easily come it at 18-1/2 pounds or under with a DA. Even with a G-62 the plane would not weight 20 pounds. The latest version of the Extra should easily finish up at 17.
