DIY: Quadruple Flying Distance - WLtoys, DJI, Hubsan, Syma Transmitter Mod

- Quick guide on extending any 2.4Ghz transmitter by over 4 times the stock range! This will work on any 2.4Ghz soldered chip soldered to the center transmit copper and outer shielding on Hubsan, WLtoys, DJI, and many other transmitters. The procedure is relatively simple if you have fine hand coordination.
I extended my range from 100 yards to 560 yards. I had to stop because I ran out of distance with line of sight to the quad. And this was with the dipole antenna turned parallel to the wave travel, vs perpendicular (better wave reception) As you can see in the video, the transmitter is not locked on the quad at times, mainly because the cloverleaf has to be straight up and down to lock on the quad and I was doing a lot of running. When straight up and down, it would bind and stay bound. Anyway, this is under bad conditions, too. The ground can normally allow waves to bounce toward the quad, but gravel/dirt is a poor substrate for this because of the irregular surface and moisture, which absorbs the waves.
Anyway, point is, I didn't have FPV enough to actually fly it around, but the spotter I was on the phone with verified flight controls. In free air, I estimate the range could be an additional hundred yards or more. If you build a directional antenna or use a patch antenna on the transmitter side, I suspect range would be increased far beyond what I have going.
Flying around in the hills, I can fly beyond the scope of my flying abilities by line of sight. :D

Awesome. You are the first person to do a clover leaf build with inches! Yeah...Thank you. You made it so simple to make a 2.4GHz clover leaf and in turn using your easy to follow instructions, I made a four lobe skew planar antenna in 15 minutes. Thanks again. You should rename your video Clover leaf antenna build for Americans.
I just now made a 4 lobe skew planar (LHCP) 2.4GHz using your method. I am going to test it out as soon as the wind stops. What I did was to just make two of the circular figure eight lobes that you made in this video. I already have several 3 leaf clover antennas. What I wanted was a back up 2.4GHz (RX) antenna for my Yuneec Q500 external antenna mod. The $20.00 retail skew planer looks just like the one that your video taught me to make for free. Well my soldering looks sloppy. But I hooked it up to my drone, and it connected right away. So I can not wait to fly with it and see if I get the same range as my store bought antenna. My transmitter is already modded with the Itelite dbs range extender flat panel kit. So no need for clover leaf. Great mod. It was so easy. Mostly because of your method, and the fact I had another skew planar to look at reference while soldering. Thanks again. I will leave a link to my video here. So you guys can see how well your method worked for me. Thanks again.
Great job explaining things and showing distance accurately! Great job overall thank you, very informative
RC flight Seeker Thanks, glad you enjoyed! :)
Excellent video. Thank you very much for all your work. I'm definitely doing this for all 3 of my quads. Good job!
Knight Wolf Glad I could help. :)
Yeah man! Good ol' antenna mods! Great video!
I've done this on a bunch of my quads, including my own WLtoys V666, Syma X5C. Mould King Super-S, 2 of 'em in my Hubsan X4D and 3 of 'em in my Devo 7e!
I buy lots of RP-SMA pigtails and Wifi Antennas! LOL
Longer range and more reliable signal without amplification, and having it connectorized it opens up options for better antennas and amps and such as well.
+Michael Thompson Absolutely, it just shocks me that companies don't take advantage of this themselves. Minor modifications on a DJI or Hubsan can push these out to 1000m without violating FCC laws.
RavingMadProductions
It's production costs and liability mitigation unfortunately.
This is a real good modification to the transmitter but I would have used some heatshrink tubing to help strengthen and to
protect the connections. Excellent modification job and doing the video review!
+Dennis Petersen Thank you! Consider using matching antennas for better range ( dipole-dipole or clover -clover combinations).
Thank you for the excellent video, very informative! Which websites would you recommend for a novice that would like to learn more theory about drone modifications?
Cool.... shows the antenna not the just output power is the key to longer range. Good job considering all theory and no test meters used. Theory works;-)
"I uhh... I don't do pink..." Lol nice video, hopefully I'll be able to do something like this for my Dromida Ominus since I plan to put a home-made micro FPV system on it for some close-quarters flying. Gonna be fun!
NoahWL1 Hehe, just wanted to clarify it wasn't mine! :) But thanks! Totally do the mod, it's been amazing. I did test with a dual dipole setup, and although horizontally it is fine, the cloverleaf transmitter with the dipole receiver actually works better. Which is weird, because it goes against antenna wave theory. I'll have to look more into it.
I thought CL sent radio waves in a corkscrew sort of way, so it sort of beats out dipoles, especially when the antennas are rotated?
Will your antennas work better (longer range )then if I replaced it with the sheld wire pulled down over itself to make a sleeve antenna on rx. And tx?im looking for the most range not to fly out of sight but so I don't lose them .will yours have more DB gain?
Great mod and a good explanation! It makes me wish I could do this on my Hubsan X4, but it has some sort of internal antenna on the board. :(
Philly Drones Oh man, it's a pretty quick and dirty job. There's a lot of signal loss and leak, but I was eager to throw it together, so I figured for this quad I'd go ahead and just get 'er done. I think done correctly with the correct dipole setup, this could easily reach 3/4 mile on stock transmitter.
hi... very Nice Mod... pls let me know, which quads are compatible with V666 TX. i have jj1000 and JJx6... what r other thn that....
ey eny one nows how to calibrate every time i try to get up from the ground it just fly to the right and the control indicator off the trottle ist allways crazy the number just keep on changing??? mi quadcopter its a v666, plis help
Your coax sure look's better than the wire connected to ebay 5db antenna's I got a few month's back.. I Love the bottom piece's you made out of coax, I would pay for a couple of those shipped to calif.
+anyshitt If you are still looking for a couple of these pieces, message me. I live in Cali and might be able to help you out. :)
I have a 9 channel radio link receiver and I'm building my own quad .. Do you think the Syma remote will work with it?
how to put the direct propeller on the engine?
real nice video man. will def make this mod. thank you so much.
btw, how do i remove the propeller cover xD
Andree Persson Thanks man! It is def worth it. :)To take the prop cover off, turn the quad upside down, you will see 4 brackets on the carbon fiber rods each held on with two screws. That's the key to removing the cover. :D
RavingMadProductions thats sick range u get man.. but how do i make the video do the same range?
RavingMadProductions ive looked the stuff up now during my lunchbreak. seems like the names for the items differ in sweden. could you link every item used in the video in the description? would be very helpful because then i could just compare the pictures!!
I actually always thought these clover antennas were only for 5.8ghz frequency (for FPV), but I've got the same setup in terms of transmitter and quad which is on 2.4 and no FPV. I've done the same mod but used a 6dbi booster antenna off a modem and an RG316 SMA cable which I replaced with the cheap and thin dipole antenna on the transmitter. Can I simply buy a clover antenna from ebay and attach it to my modded transmitter? Would i need to also have a clover leaf antenna on the receiver (quad) for it to work? Please help a noob.
How would a you mod a rx/tx that utilizes PCB antenna's? I have a skyviper and I think that the rx is MIFA and the tx is IFA. I can send you a pic of the rx if that would help
I love videos like this for sure but if you are someonee
like me, still learning phase, and haven't yet decided what equipment to
purchase for creating the "perfect package" according to my own
preferences and objectives. In a nutshell, I want racing drone speed
and performance, explorer flight time and range (say 3200 meters),
safety features like gps with rth or locate beacon, and have respectable
hd video capability. Basically, a mavik pro that isn't necessarily
all that pretty nor does it need collapsible architecture for minimizing
storage size....high tech sensors like obstacle avoidance are cool but
not in my budget so squash those features. Of course fpv equipt having
the range I mentioned....which brings me to the question of frequency
selection. Seems fpv goggles are all 5.8gh which is great quality but
lacks the range and penetrating ability of larger wavelength
frequencies. Range is the biggest challenge to understand in terms of
selecting a particular design setup, necessary components all of which
need be same system compatible.
You mentioned "repeater" in the video during the antenna construction part, something I have briefly looked into as a possible method for accomplishing long range rc.
Any thoughts, ideas, advice, explainations, etc. you can share would be helpful. I would love to see what you might put together to meet the objectives I have.
Excellent work! My question is: I have ordered the cloverleaf antennas for V666 from Banggood. Do you think they work as good as your home made ones? Also from your description i gather this doesnt apply to FPV at all or does it also increase FPV at all? Thanks
Ruidoso New Mexico Because they are precisely bent, they should actually work better than the ones I crudely bent at sub-marginal angles. :) But you are correct, this is a flight transmitter/receiver (tx/rx) mod only. The V666 already has SMA connectors on the video transmitter (Vtx) and video receiver (Vrx). Because of this, you just need an additional two clover leafs to extend video range to match. :) So two total clover leafs on the quad, and two on the transmitter/video receiver = 4 total for increasing both flight and video. Hope that helps. Take care. :)
RavingMadProductions Right on. My V666 seems lost on a slow boat from China for the past month but....I noticed I accidentally ordered an extra antenna for a total of 3. Maybe I can use 3 somehow until I get a 4th.
All my BG V666 parts orders have come in but I ordered the actual V666 from tinydeal one night when BG had the V666 at $245 (for some reason) It was a big mistake as I later noticed even though BG said it was $245 when you put one in the cart it lowered down to the normal price. Anyway I ordered from TD because they had a low price (135) which was a bait and switch anyway because the shipping was outrageous at $45. So for $45 I am still waiting here one month later with not even a tracking number yet and Paypal dispute open, and all my V666 parts for mods laying around. :)
Thanks for the vids.
Ruidoso New Mexico
Aww bummer, that sucks man! I hope it comes in soon. International shipping can always be sketchy, so I try to order from companies that give the estimated delivery dates and ship huge amounts of stuff. Anyway, keep me posted and good luck!
No problems on the vids, I love posting them. :)
RavingMadProductions Just saw that Banggood had the V666 in stock at USA warehouse for $149 so I ordered should be here this week so I can put my antennas on. Tinydeal was horrible but looks like paypal will get my money back. Antennas, bearings, motors, batteries all laying around here for weeks.Hoping to also extend the FPV range when it gets it here.
Oh wow, price has dropped even more! That's pretty good. Glad you were able to get your money back, that sucks that you had such a bad experience. I'm always nervous buying from oversees supplies unless they have a ton of good reviews. Let me know how those antennas work, I might consider a set for my FPV system.
it's possible?
What lenght of RX dipole anthenna? And looking for a iBCrazy for details of "cloverleaf anthenna"(lower leaves of clover must be in the same plane). Sorry my english. )
Sanches's games Happy to help. :) The Rx dipole antenna was 52mm total (26mm either side).
In terms of the clover, I would check on RCGroups forum for build details of iBCrazy's build. Otherwise, you can buy them for next to nothing on BangGood.com.
Sanches's games Here's a good build video, too.

hey Bro, It looks like most off the controllers that I peek into dont have a ground /shield soldered for the center mass. it looks like one shielded wire soldered to the board. what then?
+anyshitt Absolutely sure? Most antennas need the shielding soldered to transmit any real meaningful range. If they don't have that, it's not a controlled you are going to gain much benefit doing this mod anyway.
hi,, i want your advise for v666 motor upgrade can you send me a link for brushless motor .
Dev Dagar Unfortunately, the V666 does not support a brushless motor upgrade because it down not have Electronic Speed Controls (ESC) built in. You can swap out control boards and transmitters, but it would be easier to just go ahead and by a whole new quadcopter.
Hello, Can you write a complete list of components please?
+Mrsuite33 I mention pretty much all the parts in the video. The only real components that are hard to find are the SMA connectors. But they're just that, SMA connectors compatible with RG58 coaxial cable. Please see the first 4 minutes for components. :) Good luck with the build!
Can you go into a little bit more detail about the antenna that you put on the quad itself. The video is a bit out of focus when you are describing the build of that component. My question specifically ( and if you could post a picture that would be awesome!) is when you bend the wire to 90 degrees and attach another wire at 90 degrees in the other direction, you say not to cross them. Can you show a picture of what this looks like when successfully done? This is my first time ever modding anything and I am completely new to the entire process.
Thanks!
+David Orsi Hey, great question. It's fairly simple with the dipole antennas. Basically you have two metal components in the coaxial cable. The center core (transmission wire) and the outer metal shielding. What you are doing is bending the core wire at a 90 degree angle. Then you bend back the shielding and wrap a separate wire around the shielding as if you were wrapping wire around a pencil. The lead in the center represents the core wire. Basically you have the center core wire at 90 degrees and a separate wire wrapped around the shielding just below the core wire's 90 degree bend (so as not to let them touch). Hope that helps! :)
I have one of those, motor gear to wear very fast, metal motor gear worn fast.
has a solution? tried to put direct propellers on the engine, put the engine heats up much and burning the controller board.
Paulo Limm The gearing reduces amperage pull at the circuit board, which prevents damage. The only way to do direct drive would be to use smaller propellers spinning faster. Keep in mind there is an efficiency loss though, and you can only move so much air with a small propeller. You could grab propellers maybe 1/2 or 1/3 the stock size and perhaps that would work. I think you will lose max lift and speed though.
ok. thank you. how can I fix, rapid wear of the engine gear?
put lubricant on the gear, it was worse.
Paulo Limm You will have to replace the gear altogether once it starts to wear down. I'm surprised you have had problems. I have well over 40 flights onto my quad and the gears are perfect still. I'd just order a set of gears off banggood.com. :)
hey RavingMadProductions i pulled apart a wifi modem and I have taken some parts from that however, there are some differences.
the connector i have from the modem is an sma male and the antenna is an sma female, will this still work?
also there is a wire already attached to the connector, would it be alright to cut this out, strip away the rubber and then solder onto the controller? Also how to deal with the 'ground' point?
If not could you give other directions, thanks
p.s english not my native tongue, go easy
tinypic.com/view.php?pic=fonm07&s=8
picture of the wire
Conor Oates Right, you have a great little source for an antenna connector. The wire and connector from the router looks to be female to me. You determine it by the center transmitting pin. See this diagram here for male vs female:www.wellshow.com/wp-content/uploads/2010/01/sma-pcb-plug-jack.jpgEither way, it doesn't matter that much if you put a male connector on the transmitter and use a female antenna. Most antennas are male though, so it's more of a convenience thing. It won't affect transmission. :)And yes, go ahead and just unsolder that wire from the board. There SHOULD be a shielding around the center pin, which you can see is actually soldered to the board already. You would then solder that to your ground on the transmitter. The center pin goes to the transmitter solder point on the board. Here is the same picture labeled that showed the transmitter and ground wires:i57.tinypic.com/33msavc.jpgGood luck! :)
cheers dude, really appreciate that :)
np. :)
Here is my range test with the 4 lobe clover leaf antenna that I constructed based on your 3 leaf clover design method. Actually a 4 leaf or 4 lobed circular polarized antenna is called a skew planar antenna. The homemade one that I made using your method out performed my store bought antenna. Here is the video of my range test with that antenna: th-cam.com/video/kMJPYxy7Gds/w-d-xo.html
that was awesome ,my drone like yours! but i really afraid i break it ven i do it like u.....
+Ramang Seu It does take a lot of very careful work! Practice on some fine wire first, then it will be easier.
What type of coaxial cable are you using, the ones i had were very thin
You don't do pink dam man that's a bold statement ... just kidding but really pink don't stink ok ok enough laughing your vid is awesome man can't wait to try this my self on a cheeper remote I'm actual looking in to moding a few dx6i's & a dx8 by spectrum fingers crossed it works out worth a sht... LoL
It doesn't have to be perfect, right?
Im not sure about that weird units(feet, inches)
+Pablo Elizondo No, but it should be as perfect as possible, as wave theory dictates that wire length affects the quality of the given frequency you are working with.
Me encantaría volar mi V666 a máxima altura (150 mts.) pero solo llego a 50 o 60 metros porque es peligroso perderlo con un mal viento o porque se salga del rango de la señal del transmisor . Aunque tengo dificultades de comprender algunas cosas por el idioma entiendo algo de lo que aquí explicas. Tu vuelas bajo en drone V666, Quisiera verte que lo volaras a 400 mts. de altura con esa antena para animarme a construir las mías.
Te comparto algo de mi experiencia con el V666. Saludos desde Villavicencio - Colombia

Why are you calling it soder not solder
+frank jones Because.......that's how it's pronounced. Pls look it up on a dictionary with voice examples.
Why not just get an rpsma 2.4 ghz antenna from Hobbyking? They are less than ten bucks.
www.hobbyking.com/hobbyking/store/__35649__2_4_GHz_Circular_Polarized_Antenna_RP_SMA_Transmitter_only_.html
And a ten dollar extension cable.

Sure takes a lot of work out of the setup. And if you really want to increase range as long as you are LOS you can use a 2.4 ghz patch antenna.
Randall Huston You are absolutely right, you totally can, but part of my videos is doing things for ultra inexpensive, so I made one for about $0.10 worth of regular shielded wire. :)
