I have flown it on a still night to the height of 40 foot trees. It has the battery under the black canopy and flight times are ‘ok’. If you merely hover around, expect times of around 5 minutes.
As has been said in other reviews, if anything breaks other than the propellers (extras are included), you’re out of luck, because the quad’s frame IS the integrated circuit board. This thing is SO light and small, it can drop onto carpet from 10 feet and be ok. Drop it onto hardwood flooring or a hard tile floor from that height, you may not be so lucky.
This is the Electric Powered, 2.4 GHz Radio Controlled, Ready to Fly Estes Proto-X Nano Quadcopter. Now Available in Six Body Colors.
The transmitter uses two AAA batteries that are NOT included. A micro screwdriver is required to remove the battery cover. The transmitter is also VERY small and can be a challenge to anyone with large hands.
You must turn on the transmitter first … then flip on the quad by a tiny little switch on its underside. Set it down on a flat surface and it will acquire its artificial horizon. I discovered that occasionally you’ll need to reset the horizon, and that is easily done by holding the throttle/rudder (left stick) all the way to the right and down, and flip the aileron/elevator (right stick) all the way left and right quickly 4 or 5 times quickly. The front blue LEDs will blink two or three times telling you its auto-level has found the horizon.
