I honestly like the my UCD 60 with YZ FZ 1.20 better than the twist. The only downside is transporting is a bit more of a hassle. I fly the UCD at half throttle max and thats to pull out of a hover. Hovering with the UCD is much easier than with the twist. With the stock tank I get 30 minute flights because I never have to use much throttle. I have not performed it yet but I can tell that a cool transition from low level knife edge to a hover is going to be easy. I don't know if I will ever get to do it though because I put all my stuff up for sale so I can get a JR Heli Bundle.
