Comparing the two ARF's, I have to tell you the same thing.
Wild aerobatics = Ultimate
Smooth Aerobatics = Skybolt.
Although, since the Skybolt ARF is about 2# lighter than its Kit counterpart, the ARF is a bit more maneuverable than the Kit
BTW, check out the World Models Ultimate 120R also (if you decide on an Ultimate)
