will a US.60 hover
The only thing I can't do EASILY with my US 60 and Saito FA-100 is a knife edge. One of these days I'll figure out the mixing I need to do a decent knife edge. This is a maneuver I never had a problem with with the US 120 with an OS FX 1.60.
The only problem I have with hovering is my ability. Most of the time it either keeps going virtical on me or it torgue rolls and I loose coordinatiion. Recovery is easy and very positive.
