I don't know what "Alaska" is talking about. My Saito 1.80 will pull the 1.20US out of a hover and go straight up until you can't see it anymore!!! The "ONLY" dig against the big Saito is fuel consumption - it guzzles. But if you want UNLIMITED fun you got to pay for it. If you want cheap operation then use something like the MVVS 1.60 Gasser.
