Pros
1. The appearance is compact, designs have contemporary feeling, whole looks very light;
2. The flight dynamics;
3. Lighting design is beautiful;
4. Level 3 speed setting, suitable for different level players;
5. Capable of really impressive stunts like high speed acrobatic flight and high speed rotating
6. Vehicle stability is good, when a single blade is cut off , h31 can barely keep hovering.
7. Waterproof (untested)

Cons:
1 Throttle curve curt, flight, height is not good control;

1. The aircraft broke resistance is not as good as office video.
1. I cut off a blade in the flight tests, the quad can keep the hover, but difficult to control;
2. Tests, afer falling from a height (20 m or so) the aircraft cannot take off normal (suspected gyroscope is damaged, cannot take off after the throttle back, but forward together)

BTW:
I test the waterproof in the next video.welcome to click here.
The factory said the reason for waterproof is that on the circuit board of quadcopter is coated with a layer of waterproof similar coating material. So can be waterproof.Prove effective after test.
