The 4DRC F6 4K GPS Drone (hereinafter, probably just called the 4DRC F6) is a mid-sized (12.90" sq. x 2.30"), surprisingly light (192g {6.77oz.}) drone that features GPS stabilisation, a rechargeable 2S (two cell) 1,600mAh Li:Po (lithium polymer) flight battery, and the ability to tilt the camera's lens over a 45° range -- from pointing forward and slightly down to pointing farther down.

This isn't a flashlight, household lamp, Christmas light set, or other thing that glows, but it *DOES* have a number of LEDs on its fuselage (this word is definitely *NOT* pronounced "fyoo SELL' uh jee" as Drake Parker from the TV program "Drake and Josh" would pronounce it; the word is pronounced "

, so what the hey

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 and created a new website just under a year and a half ago specifically for flying machines of this nature!!! I was also attracted to something that this drone has that many others don't...

1: It has GPS -- simply meaning that it can stably hover despite any mild wind and knows where 'Home' is.
2: It has brushless motors (I tend to avoid brushed-motor quads these days because of their very short life!)
3: It has a gyro -- that means it's easy to fly even for a "craptastic" pilot like me.
4: It has all of those wonderful LEDs
5: It has an

optical flow sensor; this allows the drone to stay stable in the air even when GPS isn't present -- such as when flying indoors.

6: It has folding pylons (arms); this makes the 4DRC F6 easier to store and transport.

The 4DRC F6 is in the lower-end of being HOBBY GRADE, rather than just being another run-of-the-mill pisson toy grade drone.
It's not puny for one thing (it isn't huge, but it isn't microscopic either); and it sports BRUSHLESS motors that deliver incredible amounts of power and have a far longer useable lifetime than their brushed counterparts.

It sports a 4K camera with a 5.8GHz transmitter to furnish a live video feed to the app; both still photos and aerial video can be taken with it!

The 4DRC F6 does have a bit of a cheap feel to it, but many products of, "Hoo Phlung Pu" origin so often do.

This quadcopter is a bit more complicated to get it to take off than your average toy-grade drone...here's how to get it off the ground:

As with any rechargeable product, charge the drone first, and then you can pretend to fly a large dragonfly (well, that's what dogs would think it was if it were designed to be flown in a small living room -- you CAN fly it indoors, but you'll want a decent amount of space such an empty two-car garage at minimum!)

First off, load the app called, "4RDC PRO" (the Android version from Google Play) onto your 5G WiFi cellular telephone handset.

1: Unfold the pylons (arms) starting with the two front ones. Once that is done, unfold the two rear pylons. Place the drone on the ground.
Press and hold the POWER button on the drone (it's located on the upper surface of the fuselage) for a couple of seconds until the two white LEDs on the front come on.

2: Turn the radio on by pressing and then releasing the circular button located just below and to the right of the left-hand joystick.

At this point you may deploy the "antennae" if you wish -- or leave them folded. They appear to be decoys added to the radio for cosmetic purposes.

3: Go into your phone's WiFi settings, and connect the one named 4DRC_4K_GPS_{string of letters and numbers}.
Then launch the app.

4: At this point, you'll need to perform a geomagnetic calibration of the drone. Press the button labelled, "CALIBRATE" in the app, and follow the onscreen instructions.

When all of the drone's LEDs turn steady-on, you're ready to take off.

Pull both joysticks downward and inward (or downward and outward) to start the motors at idle speed. Now, push up on the left stick or press the Auto Takeoff button on the remote near the upper left corner, and the drone should now blast off and possibly leave an expanding cloud of dust (if you launched in a dry, dusty area anyway).
Congratulations, you're now a pilot!!!

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

On the remote control, press & hold the "OFF/ON" button for a second or so, and then release it. On the drone, press & hold the "OFF/ON" button for a couple of seconds (until the white lights on the front of the drone have extinguished), and then release it. This should neutralise both of them.

Fold everything up, place the items back into their form-fitting compartments inside the case (the radio goes near the right side of the case; the drone fits near the left side of the case), zip the case up, and go on your merry way.

The battery in the 4DRC F6 is rechargeable.

To charge the Li:Po battery in the 4DRC F6, plug the furnished charge cable into any free USB receptacle on your Pee-Cee or Mac computer.

Plug the smaller end of the USB cord into the female MicroUSB receptacle on the side of the back of the battery itself.

You should see a red LED on the back of the battery. Once the LED turns off, the charge cycle is complete and the battery may safely be unplugged from the charger.

Fully charging the 4DRC F6's battery should give you approx. 20 minutes of flying time.

To change the AAA cells in the radio, use a small screwdriver to gently push in on the button at the top of the battery door, slide the battery door off, carry it to the top of the basement stairs, and kick it down those stairs into the basement crawling with thousands of hungry silverfish that need to have a wee -- they'll think it's something yummy to eat and start chewing on it, but quickly find it unpalatable, so they all pass micturition on it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

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

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

Finally, slide the battery door back on; it will emit a soft "click" sound when it snaps into place.
Aren't you glad you didn't kick that battery door down the stairs to all those hungry, hungry silverfish that really need to go pee-pee now?

This R/C drone is meant to be used as a toy in a large dry area outdoors or a large indoor venue, not as a flashlight meant to be carried around all the time, thrashed, trashed, bashed, and abused; so I won't throw it against the wall, stomp on it, viciously chuck it at one of those wall-mounted porcelain uranators to see if it becomes broken (the drone, not the uranator!), 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 analyses, launch it into the upper atmosphere of Gamalon V** so that chairman Sonji gets all bent out of shape about it, or inflict upon it punishments that I might inflict upon a flashlight.

This drone has foldable pylons (arms) and folding props; this makes transport and storage a whole lot easier.

BigDroneFlyer1964 likeeeeey!!!

The drone uses 2.4GHz RF radiation to communicate with its radio, and its camera uses 5.8GHz (802.11ac or just 5G WiFi) to relay its photographic and videographic data back to your smartphone or tablet.

There is an optical flow sensor on the bottom of the drone; this helps to maintain the drone's position at lower altitudes. The ambient light level must be fairly high in order for this optical flow positioning system to function though, so please do not expect it to function on night missions.

I just love the living tweedle out of the carrying case! Everything (and I do mean ***EVERYTHING***) that the 4DRC F6 comes with fits neatly into cutouts in the foam for them (or into a noncloseable pocket on the inside of the case -- which is great if you wish to bring along a third or fourth flight battery): the drone itself, the transmitter, all spare props, two flight batteries, and charger cord).

The mobile phone holder on the radio can accomodate handsets up to 91.40mm (3.60") wide

On the downside are these issues.
1: Video is not saved on every cellular telephone handset; spcifically my Samsung Galaxy S5.
The video *IS* saved to my Motorola Moto E4 but is corrupted and unusable. I use a screen recording capture app called Mobizen to save my flight videos.
2: There is no option to save your flight videos to a micro-SD memory chip.
3: Punchout (throttle punch) is totally P-whipped; considering that this drone employs brushless motors, I'm quite disappointed in its performance in this regard.

Before I give it that dreadful, "Zero Stars! Whip Out Your Pecker or Sit on the Poddy and Uranate On It" rating, I'm going to give this drone one more chance using a Motorola Moto E4 cellular telephone handset as my FPV device, which I'm expecting on the late-afternoon of 11-22-20.

ALL OF THE FLIGHT VIDEOS ARE ON THEIR OWN WEB PAGE
SO THAT THIS EVAL. WOULD NOT BECOME TOO CUMBERSOME!!!

TEST NOTES:
Test unit was purchased on Ebay on 11-18-2020 and was received at 9:25am PST on 11-21-20.
I purchased a second and third battery right off the bat.

** From the Star Trek: The Next Generation episode, "Final Mission".

UPDATE: 12-12-20
As sluggish and docile as this drone is, I'm actually beginning to really like it!!!

UPDATE: 12-30-20
Near 2:00 into a flight that I made on 12-29-20, the drone inexplicably started toliet bowling, soon became unresponsive to inputs from its radio, and soon thereafter summarily spiraled out of the sky and crashed onto the tarmac.
After making some (mainly cosmetic) repairs, I attempted to relaunch but the drone refused to generate a stable WiFi hotspot. The hotspot would intermittently show up on my FPV device but I was not able to connect to it.
I power-cycled the FPV device and installed a fresh battery into the drone itself and the results were the same.

It still flies when using the controller only, but it has no GPS and video/photo capability is lost.

Therefore, that dreadful, " Failed or was destroyed during/after testing
