- I wasn't happy with the FPV video performance of my Emax Tinyhawk. I felt the i was getting a lot of multi path interference because of the dipole antenna that i comes with from the factory.
i set out to replace the antenna with the new Luminer Axii micro antenna.
This video is a little on the long side but it will cover the method that i used to remove and replace the stock antenna with the circular polarized one.
This mod made a big difference for me. in the extremities of my house i had some sever breakup in my FPV feed. No my video is much better!

**Best newbie tip** Add solder to tip to prevent oxidation before shutting off. Thank you.
I work with people who have training on how to solder and I catch them not covering thier tips when done. Then I see them with a file scraping off the oxidation a day later.
Don't use a wet sponge, use the metal ones.
i love the shit i learn on youtube comments
So you leave solder on the tip after use and then clean it off before next use?
Correct.
Great video
Good call on using the little pigtail, no point in ruining that antenna. I think I will do the same on my Mobula 7 once it gets here.
Recently toasted my 10 day old Tinyhawk 2 (your insta print mount is on the way) and think I will use it as a training ground for learning how to build/modify. Thanks for the great content!
I got the tinyhawk RTF kit as mom first FPV, I've got two line of sight flight on it now (12 batteries run through it) next nice day I'm going to try the goggles for the first time 👍👍 thanks for share this mod 👍👍

Fantastic work, man. 😊
The only thing I thought about suggesting you actually did in the end: put the heat shrink. 😃
I always forget heat shrink. There's always time to do it right the second time.
Im definitely going to do this! Parts coming in.
It's well worth it.
My cat ate my vtx antennna on tinyhawk s yesterday, as a beginner this is a life saver! Thanks so much, brilliant tutorial!
😂 You cat will get better reception now!
@@TweetFPV hopefully 😂 I've ordered new antenna, in the meantime I've shortened the vtx antenna and exposed the wire from the ground outer shell about 12.92mm - the reception is acceptable for now.. but The naughty one also shortened the Receiver antenna 😭 - should I also expose the wire tip to 12.92mm to match 5.8G frequency? Thanks a lot!
Thanks for the Video
It helped so much abd without it i couldn't have done it
Awesome mod. Thanks
Very interesting and thank you for sharing 👌 Subbed! Hafa Adai from Guam 🤙🤙🤙
Great mod thanks for sharing
Thanks for watching!
Très bonne configuration , merci
I hope whatever you said was good. Either way thank you it was my pleasure!
Nice mod, I didn't feel like changing out the VTX, so this seemed like the next best thing....
It makes a prety noticible difference flying indoors in a high multipathing environment.
Amazing. Thank you.
Since we're dealing with high frequency RF signals here, it's important to avoid any sharp peaks from solder or shielding wires because even a few millimeter tip extra can behave as a poor antenna messing with your signal.
Have a couple MMCX iflight pagodas sitting around, been thinking about doing this to my TH-S.
It can make a big difference.
Good idea. Nice work.
Thank you!
I think I'll try that with my Freestyle 2. Thanks!
Go for it!
I'm try this. I don't have much experience soldering. But I have built circuits and other diy things soldering. Been awhile. This be a challenge so small
Thanks good vid
Thanks for the adapter for antenna!!! what i was think!!
N/p
Nice work!
Thanks!
Nice tools - the holder, tweezer, heatgun, but i think you should get a smaller tip for soldering these tiny boards.
I have one I don't like how long they take to transfer heat. I do all my soldering with this chisel tip at 850deg F
Nice Mod!👍
Ty sir, thinking about doing this with the new th2 unfortunately they didn’t fix the vtx ahahah
Yea, I understand why they didn't change what they had. The Vtx isn't bad and it's about right for the reciever range. But with a cp antenna it certainly will help with multipathing.
Way better than stock antenna! May have to upgrade mine soon. Does the brand goggles factor in?
The module in the goggle helps. The rapid fire module really helps with multipathing interface.
I am just getting into this hobby ,have about 50 hours in liftoff and 2 hours of flighttime on my tiny hawk (although that is only hovering on the baclony and getting the basics)
this was really helpful since i am getting my tiny hawk next week for indoor flying and i had kinda expected bad connections indoor on it so this will defenitely be a mod i will consider,
thank you very much for sharing,i would really apprichiate it if you have other upgrade tips for one of those mini quads? props,motors,vct?
Thx again :)
Thank you for the kind words. Just the antenna mod. The rest of the Quad is good just fly it for what it is.
Sure wish I had a Tiny hawk to start with. I would have learned to fly much cheaper. Its incredibly tough. The day I received it I flew 58 packs. Probably smacked a rock wall 10 to 15 x at almost full speed. Ill need a new frame in a week or two.but I haven't broken any props. Anyone looking to start out imo this is the best way. Its really hard to beat the Tiny hawk for speed.great handling and durability. Thanks for the videos.and I promise I don't work for e max. lol. Just a great little quad!
I agree the tiny hawk is probably my favorite rtf Quad I have ever had. Emax ddi it almost perfret on this thing. Only thing they should have changed was to include the 4 blade turtle mode props.
Have you tried to flash the project mockingbird betaflight setup to your tiny hawk yet?
@@TweetFPV I havent yet, and mine flies so well I may not, but I will use the throttle boost, and a few other settings for sure. I want the throttle below half to hover. I may put more of mockingbird settings in when I have time, but right now I'm busy ripping the neck out of it. I'm ridiculously obbsesive with it, yesterday I flew from 1pm till midnight with a few breaks. I am getting so much better so much faster than training with a 5in..
Ya had me at beer....
Beer makes building go better.
Nice mod
excellent I am sold on your channel ...
Haha, I'm glad you like it!
great mod, thanks. I just got the tiny hawk 2. The video feed is horrible, simply horrible. I tried to fly it in my shop. There is a ton of room and it would be fun to fly there during the winter. However I got 15 feet away and the video was breaking up very badly. We light the shop with about 100, 8 foot 2 lamp fluorescent fixtures. Old lighting. I believe the ballasts that run the lights are causing this horrible interference. That said I did the switch to 200 milli watts on the video tx ,and have the video tx set to the fatshark band that my attitude v2s are on. I returned home and went outside, the reception was much better. I think flying at the shop is out due to the massive interference. I'll give this mod a try. Another issue, is, my quad (v2) comes with the motors soldered to the flight controller, not plugged in like the TH 1. Looks like I'll have to remove the props and the 4 motors from the frame to disassemble it. Thanks again.
Yea unfortunately servicing is a but more difficult because of the soldered motor leads. Rapidfire will really clean up the video feed.
Gr8 mod. 👍👍👍
Thank you!
been there done that, did same antenna mod to my fpv proto x... its fun while it lasts but these mods just add extra weight on these little rtf quads and thats where things just go south for these little birds...
Yea I agree, these things ride the line of power vs weight. I still get the same flight times as before for the most part.
only a few grams difference pretty much though right? I would think that wouldnt effect it much. No?
Only a few grams of added weight and I can't tell the difference when flying except that my video is way better than before.
Get some good solder wick. It will save you a lot of trouble cleaning up old solder.
It looks like the pads on the PCB would accept a surface mount IPEX-4 connector right where you removed the old antenna. I don't think you really needed that pigtail you added.
Thanks for taking time to document your efforts.
Yea I'm pretty sure a ipex connector would have fit. I just didn't have one on hand. Plus for the average person soldering the extension or bare antenna is easier than a smd connector.
Heads up for anyone trying this Mod, They have the Axii micro without a connector for sale just has a pre-tinned bare wire.
Good info. Thank you!
@@TweetFPV Getfpv has them in stock. Excellent video Thanks
Good job. I did something similar and then just replaced the vtx. I made a vid. I cut the back side of the canopy out which allows room for the antenna to pass thru. No need for a connector. 👍👍
Which Vtx did you use? Feel. Free to post a link to your video here so others can see.
@@TweetFPV ...th-cam.com/video/m5JWEX7jQHM/w-d-xo.html
great mod. I put a card in my video linking to yours for anyone who wants to replace their VTX.
Excellent video tutorial.. have you Tried Project Mocking Bird V4 for these Tiny Hawks?
It's a game changer and an easy cli diff.
No, I haven't. I was using pmbv3 I'll have to check out the v4 edition. Thank you for the heads up!
nice
Hey man great video, I'm going to order the parts through your links, one questions though, will this antena work with the glasses that come with the rtf version or will I have to buy a different set?
It will work just fine with the RTF goggles.
Great video. I have the URUAV. Do you think I could do this mod to that kwad?
Possibly. I don't have the Ur65 anymore to see how the antenna connects, but it should be possible.
Hi TweetFPV! I have the TH2 and my question is, when replacing either of the antennas do I have to reconfigure anything?
Nope

Help! I flew my tiny hawk 10 flights and lost my camera mounting screws, and yes they had a tool pack but with only one screw. Do you know what the size of the 2 screws are? or do you know where i can order some replacements?
I’m running a beebrain lite primarily as a house flyer and I’m getting really good with the gold motors indoors. Do u think I should consider the tinyhawk s or is it just a small bump up from the newbeedrone beebrain lite?
The tinyhawk is so much better that any brushed drone I've ever flown.
My tinyhawk has 2 antenna. I ordered the same one you have but i noticed the other antenna is for the camera. Im new to all this and was going to connect it to that one
Yep 2 antennas is correct. One is for 5.8 video and the other is 2.4 radio signal.
Y is my radio antenna,on the board where it says SUBS, interfere with my video? Thats the one i broke. Any suggestions
I broke the other antenna. 2.4 mhz . If thats the antenna for the radio why dont i have any video? Can i replace it with a 2.4 mhz whip antenna like the original? Or can i put an omnidirectional on this one too? And finally is it soldered the same as you did here. Thank you for your help
Also i have a fix for the usb port find a charging wire for a tom tom gps its on a 90 degree angle works perfect to get in under the axii
cool, I've found that the E6000 glue i used is flexible enough that i can just push the antenna out of the way and squeeze the usb cable into the board.
I swapped mine out on my beebrain lite and noticed literally no difference , kinda disappointed. Maybe it’s just my cheap googles that are lacking, I have a matching lhcp on my googles also
I just got mine and plan on doing this. Important question please. Im a noobie. Lol. What is the other antenna where it says SUBS on the board? I broke that one and i have no video reception. Can i buy a new one or upgrade it too? Please help. Thanks
Maybe a small hole in the very top?
Do you know of a DVR recorder small enough to fit inside?
These micros are on the edge of being too heavy. I would think that a dvr would be too heavy.
Will this improve range outside as well? I fly around a large soccer field and loose video around the small hill. Also is this the lumiere shorty or regular length?
This should give you more range. And it's the shorty antenna.
I broke the other antenna. 2.4 mhz. Can i solder a replacement like the original just like you did here? Or can i also put an omnidirectional here too?
Also why no good video thru goggles since this antenna is for the radio? Thanks for your help. Noobie
Can you join my discord and post some pictures. It will help me accurately diagnose your problem. discord.gg/N9ndyR
How has your antenna held up since adding this one?
excellent, i have bashed the daylights out of it and i have had no damage!
I don't have any issues with stock antenna. Good model though.
Also wanting a buzzer and Barometer
The buzzer isn't really needed on this quad. The Dshot beeper function i find is plenty loud enough when indoors. If you want a beeper, baro, and dvr perhaps a 2" quad might be more what you are looking for?
Hello brother! I have three emax quads, and want to do this to my tinyhawk. Where could I buy the pigtail to connect the antenna? I purchased the micro AX2 5.8, but im a little concerned with the direct solder. I would rather do the pigtail/shrink tube method. I have been in the 3D heli scene for 8 years, bought a blade 350QX, and a blade nanoQX, Never thought the tiny FPV quads would be so addictive........ I thought the helis had a hold on me............Im so addicted. Thank you so much.
This is the pig tail i used in the video amzn.to/34aCQgk
Okay after banging my head against wall you solved my problem, correct me if i'm wrong... you did this to change from linear pole antenna to RH circular polarization correct? hope you answer, all our mini quads use linear and we use RHCP antennas on our googles = bad signal . correct?
Yea I did this to change from linear to rhcp. With a rhcp (or lhcp) it really helps. The nature of these quads is to fly indoors so there is usually a LOT over multipathing. The circular polarized antennas really help cut down on that. When we race indoor races the other people using the same goggles and recievers are shocked at how much better my fpv feed is.
Damn it! I tried changing my antenna and still choppy video for me. So my vtx has to be the problem. Thanks for the great videos.
take a look at this mod: th-cam.com/video/m5JWEX7jQHM/w-d-xo.html
Very true noob here but I have a question, should you change the other antenna also? I think people refer to it as the rx antenna? I don't really have a clue of what I'm talking about as you can probably see. Otherwise thanks for posting this, it was very informative.
No the rx antenna is fine and a whip is usually good enough since is a lower frequency 2.4ghz it has better range and penetration that 5.8ghz video signal. Rx and tx are industrial teams. Rx is reciever and tx is transmitter. Oh and just for fun wx is short for weather.
@@TweetFPV Great, thanks for the clarification. I have another question, I'm going to get the Eachine vtx 03s and the
"Caddx Turbo EOS2 1200TVL 2.1mm 160 Degree 1/3 CMOS 16:9 Mini FPV Camera NTSC/PAL" and I was considering swapping out the vtx antenna. I see some on Amazon that come in a two pack "nidici Foxeer Lollipop 3 FPV U.FL Antenna 5.8G 2.5DBi Super Mini RHCP Antenna UFL for RC Drone FPV Quadcopeter Multicopter TX/RX (85mm)". I only need one though right? Would the other just be extra? I don't know if they need to both be used to work together. I have the Eachine ev800D goggles. It comes with two antennas on the goggles, one patch looking thing and another round style. I'm figuring whatever VTX I have, upgrading the antenna would still be a great move. Thoughts? And thanks in advance.
Yea the 2 pack one would be extra. The only thing you need to pay attention to is if the antennas are rp-sma or sma. Google some images and make sure they match what your are connecting them to. The other thing is the polarization. If you run right hand circular polarization then make sure your goggles have the same. If you have a linear antenna like what's on a lot of micros you can run lhcp or rhcp it doesn't really matter then.
@@TweetFPV Thanks again man for helping out. I subbed already. How do I know if the goggles have RHCP? When I go to the specs on that unit it says includes 1x clover antenna and 1x Panel antenna. I will look at the rp-sma or sma as you suggested. The link to the goggles...www.eachine.com/Eachine-EV800D-5.8G-40CH-Diversity-FPV-Goggles-5-Inch-800*480-Video-Headset-HD-DVR-Build-in-Battery-p-859.html
And the link to the antennas I was considering is www.amazon.com/nidici-Lollipop-Antenna-Quadcopeter-Multicopter/dp/B07JFFP4LZ/ref=sr_1_4?keywords=lollipop+antenna+vtx&qid=1578698013&sr=8-4. I was just going to cut the end off and solder it directly to the vtx since I don't have the fancy adapter that you used.
Does the weight affect the flight time or the way it flies? I would like to do this mod to a few of mine..
Not a noticeable change In flight time or flight performance
Will it still work with the all in one package ? It will still work with the eMac provided goggles ? Big thanks !
Yea it will work with the all in one kit.
What did you use to secure your LED's to the frame?
Hot glue. Be careful the styrene frame melts easily.
what batteries do you use for the tiny hawk to get best performance and flight time?
Gnb 450 1s hv
im hopeing my tiny hawk comes in the mail tomorrow.
It's 2018, everyone raise your hand if you're waiting for a brushless whoop in the mail! hahaha
I'm excited to see what the 2s tinyhawk and the eachine trashcan are like.
@@TweetFPV Hey, it's only money, lol.
As of this morning, I am the proud owner of a Mobula 7. I felt like a kid getting a puppy after all the wait, lol.
The mob7 looks like a total rush to fly!
Will a U.FL SMT connector not fit in that very space?
Possibly. I used the extension to make this mod easier for people that aren't great at soldering things like smd components.
I now older vid...just saw it for the first time today ( 5/21) could you just have cut the older antenna and then soldered that newer disconnect one to it without detaching from board ? would that have been easier? curious. And can't you do the same for all micro quads that have a dipole type antennas?
Yea you can do that but it would require you to desolder the antenna from the board eveytime you took the frame off. That board is only going to survive a few heat cycles.
@@TweetFPV never thought of that...Thanks for the reply and subbed
@@FlyingBuzzard Thanls for the sub!
Does turtle mode work now, whith the antenna so far up? Any handling difference compared to stock?
No change in handling and turtle mode still doesn't work. The stock props don't provide enough thrust in reverse to flip the tinyhawk.
to bad, was hoping for a "double winner"@@TweetFPV
Anybody tried to add GPS to the Tinyhawk already? 😋 J/k, nice vid.
Haha! Love your logo Btw.
Thanks mate :)
can i bind with frsky taranis x9d plus?
Yes. You can bind this with anything that works with frsky in d8 mode.
Would this mod work using the original googles the rtf come with?
Yep. It's all the same.
Couldn't you just have spliced into it externally?
Heard some reviewers mentioned that the Tinyhawk will work with flysky receiver soldered on. Haven't seen any videos of anyone actually done that yet. Can you confirm if it will work? Thank you
There are provisions to solder on a different rx of your choice. It would need to be a very light and small rx.
@@TweetFPV Noted. Thank you very much
I just bought the Tinyhawk, and I only have a flysky radio so I picked up a micro flysky receiver to put on it. I'll let you know if it works!
Good luck. Let us know if you run into any problems.
@@FPVisioning Hope it will work. Keep us updated as soon as you can. Thank you
The antenna on my tinyhawk 2 is all messed up. I’m trying to find info on replacing it. But maybe I should just do this
It will certainly help with multipathing in an indoors environment.
can I do this mod with only the antenna and not the connector you used?
Sure you can use just the antenna.
If i wanted to direct solder that anttena to the vtx would i need to follow the same procedure you did cut the connector off pull back the braid solder ground and signal ?
yes, exactly!
@@TweetFPV thanks a lot
@@TweetFPV one more thing is anyway to put a different vtx in?
Cause they have micros that go to 200mw just wondered if thats was even doable cause it looks like its all one piece but cant tell
you can put a different vtx in this model you are just limited on space.
Hi I was thinking of doing this to my tinyhawk freestyle... the original antenna is cut... do I have to worry about the length of the antenna?
No, it really doesn't matter.
@@TweetFPV awesome thanks
Could I just get the longer one you think and not use the disconnect? And now what antenna would you get for your goggles to go.with that?
Yes, you certainly could use the longer one. If your get a rhcp antenna on the tinyhawk, then any rhcp antenna on your goggles will work. If you have a diversity setup a rhcp patch antenna on the goggles would make the complete set.
I'm not sure I got the kit. So the emax goggles that come with it. Is that a diversity setup?
I can't tell if they are true diversity or antenna diversity. They do have 2 antennas that you can swap out for any style you like. I have used them and can say I was very impressed with the image quality. Compared to the eachine 007 and 006 these are much better.
I think you need circular polarized antennas on the googles then, right?
For the maximum advantage yes.
thx for answering, means dipol would still work on googles. Interesting. Which google antennas would you recommend to match the AXII? I have got only the EMAX RTF googles by now. BR Olli

is this for better range or video ?
cause mine seem to drop out of the air afther im 10/15m away
Video. If yours failsafes at 10 meters you have a problem. Are you using the kit radio or something else?
@@TweetFPV im using a tarranis q7s the tinyhawk was my first drone and i asumed that was just my range, i recently bought a uruav wich can fly trough my entire house
Yea you should get much better range than that. Are you bound to it in d8 or d16 mode?
fine. very good video. thank you so much.
left to determine. Which is better emax tinyhawk or happymodel mobula7. With Happymodel Mobula7 you can use 2S to fly outside. And good luck. and Ukraine is waiting another video. super
Mobula7 is much better. I have both and I never fly the Tinyhawk because the video is terrible...and 2s is great outside.
I already have a snapper 7. Do you think its worth it to buy a tiny hawk?
How is it better than a snapper 7?
Thanks, Tweet
I have both the snapper 7 and the tinyhawk. I don't fly the snapper anymore. Reason being is the snapper is heavier and more destructive to its-self, my house, and "soft targets" with that aluminum frame. the tinyhawk is purpose built with each component being part of a "system" the snapper is just a bunch of parts, be it good parts. With that said, would i recommend buying the tiny hawk over the snapper 7... YES!! would i recommend buying a tinyhawk if you already have a snapper 7, possibly. the reason being for me because of the group of people i fly with and do indoor races with i don't want to mess up their houses when it comes to race day. The snapper 7 is just a bit more anit-socal than the tinyhawk..... Hopefully some of that makes sense.
So tinyhawk is only better in social? Is there any difference in fc or something?
Do you think its worth it to spend 99$ on another micro quad? Or recommend me something else to buy with 99$!!
If you have the snapper and are happy flying it spend you cash on liops. If you are somewhat serious about racing get the tinyhawk. I can think of a better indoor Quad for $99.
Thanks, Tweet
I’ll just buy lipos or vtxs.
If you haven't tried to setup project mockingbird on your snapper 7 yet I highly recommend giving that a go.
You would have much easier time to get the old solder away from the board with a wick. If you want even better results, get some high quality flux, too. Try watching some videos by Louis Rossmann to figure out how you should use the flux and wick to remove pretty much everything very fast.
What is the AUW now that you did this?
30g without lipo
@@TweetFPV awesome, thank you!
You drink PBR, but its in a glass bottle. I'm so confused.

Can it be also done without the beer?
Well possibly. I haven't tried yet so I can't say for sure.
Wow this looks somewhat simple but very difficult to do, at least for me 😅
There are easier ways. Last one I did I just direct soldered and cut a channel behind the camera to route the antenna out.
@@TweetFPV ok thanks. what is direct solder and how does it differ from what you showed here?
Same thing just without the ufl connector piece.
