This isn't a flashlight, household lamp, Christmas light set, or other thing that glows, but since I love things that fly, what the hey.
I have only evaluated a few remote controlled (RC) flying toys before, so please bear with me here.

This is the model TW-781. It is a very small, lightweight, easy-to-fly remote controlled aeroplane. It fits in the palm of your hand, and is very light in weight (just 9.0 grams). It is designed exclusively to be flown indoors; its construction is such that you won't gouge holes in walls or break lamps when you crash (note I said "WHEN", not "IF", because you WILL crash it at least a few times while learning to fly it!!!).

SIZE

This toy is remarkably easy to use for an aeroplane...here's how to get it flying:

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 thinks it is).

1: On the bottom of the aeroplane's fuselage (this word is definitely *NOT* pronounced "fyoo SELL' uh jee" as Drake Parker from the TV program "Drake and Josh" would pronounce it

) (body) under where the cockpit is, there's a tiny on/off switch.
Use a fingernail to slide this switch toward the front of the aircraft to the "on" position.

2: On the remote control, turn the "on/off" switch to the "on" position.

3: Hold the aeroplane level (or place it on a very smooth floor if you installed the landing gear), and push the left hand stick on the controller up (toward the front).

4: If hand-launching, gently throw the aeroplane forward; it should now be flying. Be certain to aim the remote control at the aeroplane at all times.

5: Push the right-hand stick on the remote to the left to turn the aeroplane port (left), and push the right-hand stick on the remote to the right to turn the aeroplane starboard (right).

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

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

The battery in the aeroplane 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 back of the controller off, very gently place it on the ground, and kick it into the garden so the hungry, hungry praying mantids will think it's something yummy for their little insect tummies and subsequently strike at it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

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

Insert six 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.
Aren't you glad you didn't kick that battery door into the garden with all those hungry, hungry praying mantids now?

Here is what a praying mantis looks like.
I found this guy on the morning of 09-08-06 clinging to the basket of my scooter.

To charge the battery in the aeroplane, slide the door on the lower portion of the top of the remote control open.

In the compartment you just exposed to atmosphere

, you'll see a thin cord with a small plug on the end.

With the aeroplane turned off, plug this into the small receptacle for it on the bottom of the aeroplane's fuselage (body), under the cockpit.
This connector is keyed to fit the receptacle on the aeroplane only one way; please do not force it or you may irreversibly damage the aeroplane and it won't fly for you again once its flight battery goes to pot.

Turn the switch on the remote control to the "ON" position. Both red and yellow-green LEDs on the remote should now come on.

After a maximum of 30 minutes, the lights on the remote should turn off. When this happens, turn the remote control's switch to the "off" position, gently unplug the cord from the aeroplane, stow the cord in the remote control's compartment, and slide the door back closed.

This should allow a flight time per charge of the aeroplane's battery at between ten to 15 minutes.

The Micro Cessna 781 RTF R/C Aeroplane aeroplane is meant to be used as a toy in a dry area, not as a flashlight meant to be carried around, rained on, thrashed, trashed, and abused, so I won't try to drown it in the toilet tank, bash it against a steel rod or against the concrete floor of a patio, let my mother's big dog's ghost, her kitties, my kitty or my sister's kitty cat piddle (uranate) on it, hose it down with my mother's gun, run over it with a 450lb Quickie Pulse 6 motorised wheelchair, stomp on it, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, pee on it, or perform other indecencies/potentially destructive test on it that a regular flashlight might have to have performed on it. So this section of the web page will be significantly more bare than this section of the web page on a page about a flashlight.

The transmitter uses IR (infrared) LEDs, not radio signals, so you do not want to fly this aeroplane outdoors in the sunlight.

The remote control's maximum range is 10 meters (approx. 33 feet).

This is the remote control.

And this pic shows the blue LED in the aeroplane's fuselage.
