This isn't a flashlight, household lamp, Christmas light set, or other thing that glows, but it *DOES* have a bunch of LEDs on its undercarriage, so what the hey.

This is only the twentieth {?} R/C helicopter (well, quadcopter or even drone!) to have graced these pages (out of at least a thousand other products) over the last fifteen-plus years this website has been online, so please play nice and don't bite my head off to tell me that I forgot some important detail.

I love things that fly; that's why I took the bate and also why I added a seperate section titled "PRODUCTS DESIGNED TO FLY" on my website a number of years ago. I was also attracted to something that this drone has that many others don't...

It has a gyro -- that means it's easy to fly even for a "craptastic" pilot like me.

This is a medium-small, lightweight (I), easy-to-fly 4-channel remote-controlled outdoor (and indoors with a large enough space) drone. Its remote uses RF (radio frequency) radiation.

It sports a camera; both still photos and aerial video can be taken with it!

This toy is remarkably easy to use for a drone...here's how to get it off the ground:

As with any rechargeable product, charge it first (see directly below), install the flight battery, and then you can pretend to fly a dragonfly (well, that's what the kitty cat would think it was if it were designed to be flown in a small living room).

1: Place the drone on the ground so that the tail faces you.

Move several feet away from the drone (at least six feet away).

2: On the remote control, turn the "on/off" switch to the "on" position. A fairly loud, single "beep" should issue from it.

3: The yellow-green light on the remote will now come on and start blinking. Push the left-hand stick on the remote control forward and then let it go back. This "arms" the drone. If you did this correctly, that yellow-green light will go from blinking to steady-on and the R/C should emit a series of three tones in rapid succession.

4: Gently push the left-hand stick on the remote control forward a second time -- but do so more gingerly this time so that the drone doesn't just blast away -- it has a good deal of thrust, so the possibility of it getting away in this manner does exist.

5: The UDI U818A 2.4GHz 4-Ch. 6-Axis Gyro R/C Quadcopter w/ Camera should now lift off the ground. Congratulations, you're now a pilot!!!

For additional instructions & tips on how to fly, please read the instructional material that comes with the product.

To take an aerial photograph, press & release the button on the front of the Tx near the lower left with the 'camera' graphic printed next to it.

To shoot realtime aerial video, press & release the button on the front of the Tx near the lower left with the 'video camera' graphic printed next to it. Press & release it again to neutralise the recording of video.

There is another button on the lower right face of the remote: this button has the phrase, "Light control" printed next to it. All this button does is toggle the flashing tail boom lights and the headlight on and off; it might behoove you to neutralise these lights during daylight flights to help the flight battery last a little longer.

Turn the remote control off when finished using it.
Same switch as before, but slide it in the opposite direction this time.

The battery in the UDI U818A 2.4GHz 4-Ch. 6-Axis Gyro R/C Quadcopter w/ Camera itself is rechargeable; however the batteries in the remote will need to be changed from time to time.

To do this, unscrew & remove the phillips screw from the battery door on the underside of the unit, using a small phillips screwdriver (the #0 from my set of jeweller's screwdrivers worked well here). Set the screw aside.

Remove the battery door, carry it to the top of the basement stairs, and kick it down those stairs into the basement crawling with thousands of hungry piss ants that have to piddle -- they'll think it's something yummy to eat and start chewing on it, but quickly find it unpalatable so that they drag it to the queen, who also finds it distasteful so she pisses on it and instructs the worker ants to do the same...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Remove the four used AA cells from the compartment, and dispose of or recycle them as you see fit.

Insert four new AA cells into the compartment, orienting each cell so its flat-end (-) negative faces a spring for it in each chamber.

Finally, place the battery door back on, and screw the screw back in.
Aren't you glad you didn't kick that battery door down the stairs to all those hungry, hungry piss ants with full bladders now?

To charge the battery in the UDI U818A 2.4GHz 4-Ch. 6-Axis Gyro R/C Quadcopter w/ Camera, take the thin cord that's attached to the "wall wart" charger, and plug the small end into the rectangular receptacle at the end of the battery's cable.

Plug the "wall wart" into any standard (in north America anyway) 110 volts to 130 volts AC 60Hz two- or three-slot household receptacle (or "outlet" or even "wall socket" if you prefer).

When the charge cycle is in progress, the red LED on the charger will turn on and operate steadily (e.g it should not blink). When the charge cycle is complete, this LED should turn yellow-green.

You may then safely unplug the battery from the charger, and unplug the "wall wart" from the AC receptacle.

Fully charging the UDI U818A 2.4GHz 4-Ch. 6-Axis Gyro R/C Quadcopter w/ Camera's battery should give you 6 to 10 minutes of flying time.

This RC drone is meant to be used as a toy in a dry area outdoors (or in a large open room indoors), not as a flashlight meant to be carried around all the time, thrashed, and abused; so I won't throw it against the wall, stomp on it, try to drown it in the {vulgar slang term for a fudge bunny}bowl or the cistern, run over it, swing it against the concrete floor of a patio, bash it open to check it for candiosity, fire it from the cannońata (I guess I've been watching the TV program "Viva Pińata" too much again

- candiosity is usually checked with a scanner-type device on a platform with a large readout, with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; and the cannońata is only used to shoot pińatas to pińata parties away from picturesque Pińata Island), send it to the Daystrom Institute for additional analyses, or inflict upon it punishments that I might inflict upon a flashlight.

So this section of the drone's web page will be significantly more bare than this section of the web page on a page about a flashlight.

The range of the radio in the Tx (RC hobby talk for "transmitter") is not stated at all, but should be at least ~152.40 meters (~500 feet); frequency is stated as 2.4GHz.

The unit has a 4-channel remote control; this allows for forward / backward / up / down / left / right movement (movement on all three axes -- X, Y, and Z). It also has a fully proportional control system; simply meaning that the motor speeds can be varied depending on how far you move the joysticks -- it isn't simply "full power and no power at all" like some other R/C products.
