sensor in the quadcopter. The flight characteristics of the Hubsan X4 are probably best described as floaty. Sadly the difference is in my opinion negligible at best. But when Hubsan announced the X4 product line, that dream Id given up on of an all-purpose quadcopter with a good enough camera came back. Out of the three variants announced over a year ago (excluding the X4 Pro, which I consider a whole other story at least two are finally starting to show up at retailers: The camera equipped H107C and the FPV ready H107D, this being the former. A noteworthy example of what I mean is the battery, which is now proprietary. Flight time: 7 mins, charge time: 70-80 mins, transmitter rates: 2 (customizable). Its mostly a bust and no one is more saddened by this than. Instead of having a direct, forceful response it has a slower, measured response. The camera is the one thing I personally wouldve wanted to see improved versus the original. What kept bugging me about the original even as I got better at flying it (and probably the reason I eventually got rid of it) was the camera. If nothing else, I want to give them credit for trying something new.
