I cannot help with any firsthand information. I am also considering a purchase like that and have been researching it. I can't find any reviews of the SkyFly, but there are a number of people very impressed by their T-Hawks, espeically the durability, and I haven't found any real negative comments on it, either. That one is looking like a good bet to me.

Hopefully somebody can chime in about the SkyFly. It looks like it has better landing gear than the T-Hawk. The controller looks like it has two sticks. Not sure how it works, though. The T-Hawk's controller incorporates pitch and turning into a single stick, which I think is a good thing.
