I have about 20 flights now on an Sebart Angel 50e and my experience is much the same as Andrew's. I had a bit of trouble with a touch of wing rock coming out fast from downline manoeveres but was able to dial that out in a few flights. One additional observation I would make is that the instant you centre the sticks when in any kind of rotational manoever the plane rotation (in whatever axis) just stops dead. It is like flying a plane with absolutely no rotational inertia.
I am very impressed with the iGyro. Just wish that I had not lost the jet in which I was intending to install it.
