The Ultimate is a bit more agile and can get a little more radical that the Skybolt. But the Skybolt is a bit smoother and more stable.
That's not to say it can't do aerobatics
Yup, and with it's longer tail, the Skybolt tends to track better and have little to now yaw at runup... where as my Ultimates tend to yaw fairly well during takeoff.
It's trivial to grease or three point a Skybolt's landing. It's much harder with the Ultimate.
The Ultimate snaps much better.
