This isn't a flashlight, household lamp, Christmas light set, or other thing that glows, but it *DOES* have a white LED on the front of its canopy and a white LED backlight in the radio's LCD), so what the hey.

Please play nice and don't bite my head off to tell me that I forgot some important detail; this is only my fourth experience with a non-coaxial heli.

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 two things that this heli has that many others don't...

1: It's much larger than any of the "micro" helis I have flown before -- I specifically wanted a larger model.
2: It has a gyro -- that means it's easy to fly even for a "craptastic" pilot like me.

This is a fairly large, lightweight (as a helicopter in a metal & plastic body goes), easy-to-fly 4-channel remote-controlled outdoor (and indoors with a large enough space) helicoper. Its remote uses RF (radio frequency) radiation.

It has a gyroscope (very commonly abbreviated to just "gyro") in it that makes this heli exceptionally stable and lets slow-speed maneuvers and hovering be accomplished much more easily than it would be in R/C helis without a gyro.

This toy (some people might call it something other than a "toy") is remarkably easy to use for a helicopter...here's how to get it off the ground:

As with any rechargeable product, charge it first (see directly below), 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 heli on the ground so that the tail faces you. On the left side of the helicopter's body (on the metal part just below and behind the cockpit), there's a female receptacle. Plug the smaller of the two short cables (the one with the red plug) into the receptacle. It is "keyed" to fit only one way, so if it doesn't fit, turn it 180° and push it in. Slide the little red switch to the "ON" position. The heli will emit some beeping noises when you have accomplished this correctly.

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

2: On the remote control, turn the "on/off" switch to the "on" position. The remote will emit a series of beeps -- this is perfectly normal. After several seconds, the white LED "headlight" on the front underside of the heli's canopy will turn on.

3: Light fuse and get away...

4: Push the left stick gently and slowly up. The helicopter 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.

Turn the remote control and the heli off when finished using them.
Same switchs as before, but slide them in the opposite direction this time.

The battery in the helicopter itself is rechargeable and is not designed to be changed; however the batteries in the remote will need to be changed from time to time.

To do this, unclip the battery door on the underside of the unit; it's on a hinge so I don't have to tell you to 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 piddles on it and instructs the worker ants to do the same...and then rather emphatically say, "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, swing the battery door shut and push in on it until it latches shut with an audible "snap" sound.

To charge the battery in the helicopter, take the thin cord that's attached to the "wall wart" charger, and plug the small end into the charging box.

Plug the "wall wart" into any standard (in Europe anyway) 110 volts to 240 volts AC 50Hz or 60Hz slot household receptacle (or "outlet" or even "wall socket" if you prefer).b If you live in north America, you'll want to procure a European to American outlet adapter -- no step-down transformeer is necessary.

(Please be certain that the helicopter is turned off at this point).
You'll see a cord with three wires and a white connector on its end. Plug this one into the receptacle for it on the charger.

When the charge cycle is in progress, a rednLED 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 off.

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

Charging is advertised to take 45 minutes when the battery in the helicopter is essentially fully discharged (flat).

Fully charging the helicopter's battery should give you 6 to 8 minutes of flying time.

This RC helicopter 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 cannoñata (I guess I've been watching the TV program "Viva Piñata" 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 cannoñata is only used to shoot piñatas to piñata parties away from picturesque Piñata Island), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that I might inflict upon a flashlight.

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

Stated range of the radio in the Tx (R/C hobby talk for "transmitter") is 50 meters (~150 feet); frequency is stated as 2.4GHz.

The unit has a 4-channel remote control; this allows for forward / backward / up / down / rotate left / rotate right and slide left / slide 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.

This heli is rather large and powerful; it could be termed a "
cat slicer" or even a "cat killer" if it were flown indoors in a pet-owning household, so please excersize at least a modicum of care when flying it in the house.

Brief maiden flight of my Wltoys V913 4-Ch. Sky Dancer Single Blade R/C Helicopter 09-24-15

Flight took place over a vacant lot near the intersection of Ellinor Ave. and Summit Dr. in Shelton WA. USA on the afternoon of 09-24-15 (or, "2015 24 Sep." or even, "September 24, Twenty Stick-Bent-Stick" if you prefer).

Weather conditions at flight time were partly cloudy, temperature of 74°F (23.3°C), and winds reported as being from the WNW at 4.7mph (4.06kts, 7.57kph).

That thing that you see at the top of the video is part of the heli's fuselage; I had the camera mounted to the skids.

It was a bit too windy to fly, so the heli did a power dive into the street, causing two of the connect buckles to fly off. I ordered a set of replacements; they should arrive by 10-05-15 after which flights can resume.

This video is 10.969975357835 megabytes (11,022,911 bytes) in length; dial-up users please be aware.
It will take no less than fifty five minutes to load at 48.0Kbps.

Product was purchased after the V912 was damaged beyond repair; the V912 was given to me as a birthday gift on 09-16-15.

Because the connect buckles came off at the termination of its maiden flight and replacements will not arrive for nine or ten days, the dreadful, "" icon will be temporarily appended to its listings on this website -- but TEMPORARILY of course because I'll be flying this bird again real soon unlike my V912 which was mortally wounded and will never fly again.

UPDATE: 10-02-15
The replacement connect buckles arrived on 09-30-15, and I wasted no time installing them (with photographic assistance from holtneil on RCGroups.com -- thank you!!!) and giving it avery brief test flight just to be certain that it could hover and turn, so that dreadful, "" icon can now be removed from its listings on this website.

UPDATE: 10-05-15
On a flight that I made on 10-03-15, the heli crashed directly into a telephone pole, causing the canopy to disengage, the flight battery to fly out, the flybar to become broken, and two of the connect buckles to pop off & become lost. As a direct result, I can no longer fly this bird that dreadful, "" icon will be put back on its listings on this website.

Replacement parts have already been ordered; ETA is just short of Halloween 2015.
