I had problems with the propellers coming off, a little dab of thread locker in the prop hole fixed that then let it sit for a few hours then fly it. I got 3 750mAh batteries this increased the flight time. I found the sensors are quite sensitive so you have to be prepared for sudden moves away from objects, altogether a fun machine but not for beginners because of the IR sensors. The body is pretty flimsy though.

Very fun to fly but 4 stars because the sensors don't work very well.

Relatively easy to fly, although onboard stabilization software susceptible to gyro and accelerometer drift typical of these parts.

When part arrived, lower left motor cable was pinched during factory assembly, and slightly pulled out of connector. This lead to quad tending to pitch uncontrollably. A quick recrimp and redressing of cables fixed that. CHECK the connectors when you take it out of the box

This quadcopter drifts a lot and trimming did not help much. The IR sensors will only work well in a large space, try using it in a room and it will be flying all over and end up crashing into something as it over reacts to items in the room.

The altitude hold works but became more of a problem when used in doors and there are furnitures and stuff around.

Ended up turning off all the sensors and noticed that it would suddenly climb on its own and lowering the throttle slightly caused it to come down to ground instead of stop climbing or lower its altitude slightly.

Quite hard to fly in a small area.

Nice looking ,on first flight took of to left hit corner of wall and broke one leg easily ; fixed with some steel epoxy . Need to initialise on ground with transmitter to set 0 altitude. It suddenly jumps up while passing over obstacle-altitude held by ultrasound ( table for example ) and can hit the lamps ( so not for home ) . Obstacle avoidance works OK only for large spaces like a small hangar as it swings fast away from obstacle only in low speed ( so if something near on opposite side - it hits ) if going fast - it will hit , weak obstacle avoidance from front ( maybe because of the protruding nose impeding infra-red signal)-practically it hits . It can become home-worthy if the algorithm of obstacle avoidance leads to stop movement rather than swing fast in opposite direction . May need to add top-ceiling sensors so not to roof. Fun in large spaces with flat surface ( no,furniture) not for home . No position hold , so it drifts all the time , forget using a camera as FPV - next to impossible to control in tight spaces .
