Here’s and in-depth review of the Cheerson CX-10D Nano, available here:
The CX-10D seems like a great little Nano quad with altitude hold capabilities! Fun, stable, small and light not to get in trouble with or hurt anyone while learning. I would highly recommend this for anyone who wants to get into quads. You really should learn on something like this first. Once your comfortable flying this for a while you should then move up to a larger more expensive quads.
I’m giving away drones here!
