Installing Fat Shark Predator FPV Goggles to DJI Phantom Quadcopter with GoPro Hero 3 Camera

[@kevincalvey9281]

I don't typically comment on youtube but I felt this was such a great tutorial I just had to throw some gratitude your way. I have a Phantom inbound right now and want to do exactly what you did, GoPro Black run through to the Fatshark Predator! I especially appreciated the scrolling text providing specifics on where and what you had to purchase extra. GREAT tutorial and thank you again!

[@RC31800]

Best video on Phantom FPV setup on KZbin I think!!

[@hervegaerthner6524]

Thanx a lot. I bought a DJI Phantom+Hero3+Fat Shark Predator 3 days ago. your video is the best I found : so great to see the Gopro video in the goggles...and no need to make holes and no need to open the Phantom. Thanx for sharing, best regards.

[@ghonis]

Hi Chandler, For the individual red and black wires, 1/16" diameter is a good size. A 1/4" diameter heat shrink can be used over both. I use an assortment pack of heat shrink tubes I bought years ago from Radio Shack with 1/16", 1/8" and 1/4" shrink tubes.

[@ghonis]

Hi Steven, Yes, the GoPro records the captured video to its micro SD card and at the same time transmits the video to the fatshark goggles. I haven't noticed any lag or reduction in quality. I set the GoPro to its 1440 resolution mode because it is in the 4:3 display ratio and displays better in the fatshark goggles than in the 16:9 1080 resolution.

[@voltron979]

That was one of the best explain videos on how to do this the very right way..! Thanks for that Mr.Gary !

[@Nitehawk-tl3jv]

Thanks for the great tutorial. I have had a Hero3+ and just picked up a DJI Phantom but wasn't sure how I wanted to set up a live feed. Your video made it look like it is something I should have no problem imitating. Thanks again.

[@ralphmatile2723]

Thanks for taking the time on this, it was extremely informative and helpful!

[@tgifhounds]

I just discovered the Phantom tonight and accessories like this tonight and am very intrigued. Thank you for the great "details" on how you go about this.

[@andrecato]

Gary, Thanks for the great insight. Very well constructed, explained and convincing! Thanks again for your efforts!

[@coopytroop]

This is one of the best Phantom-related How-To video's I've watched! Great Work and thanks for the help!!!

[@coopytroop]

P.S. have you since installed a gimbal of any kind? I'd love to see a how-to including the fatshark and the gimbal connected done by you.

[@ghonis]

Hi Ben, No, I haven't installed a gimbal and have no plans to.

[@coopytroop]

Fair enough. Well great job again on the video anyhow. All the best!

[@Bondibites]

Very well done, thanks for taking the time to put this together so thoroughly.

[@GeorgeZoto]

Thank you for the detailed instructions! Maybe include a short clip of flying it too next time ? Thanks!

[@ghonis]

George Zoto Hi George, Glad you liked it. I have a KZbin video of it flying here: kzbin.info/www/bejne/jKiQgHqoZd-Sb6s

[@ghonis]

Hi Colby, I am a novice flyer with the Phantom so I fly in GPS mode. I fly in wide open spaces and haven't noticed any lag time or delay.

[@MrBabyboy4896]

Great vid. I think I'm going to try that set up on my Hali 500 but I think I'm going with another type of antena. I have seen some that are flat with good operation reception.

[@ghonis]

Hi Audley, I have since replaced the original antennas with 5.8GHz Circular Polarized Antennas (SMA) for RC 5.8G Transmitter/RX FPV FatShark RC.

[@d.hansel854]

I wonder in time will the DJI quad copter people have this mod already incorporated on their quad copters? It sure would be nice if they would have the wiring done so you can use either the FatShark goggles or the SkyZone goggles. Thanks for a nice video. How about some feedback....

[@mbnyus]

Fantastic info, thank you for the detailed video.

[@ManofWater]

interesting, I'm using field monitor think i may try the goggles soon

[@baileymoto]

Great video. Extreme newb here wanting to get into FPV and this has sealed the deal for my planned set of parts. Thanks.

[@ColbyStewart1965]

fantastic video! Very well done! How do the goggles work; is there any lag time or delay when flying FPV? Thanks again!

[@lancethrustworthy]

Thanks. You've started to shine a light on the FPV situation with DJI. I understand there are concerns about the Hero 3's WIFI frequencies interfering with remote control. What frequency is the Fatshark system operating on?

[@ghonis]

The Fatshark Predator Goggles use a 5.8 GHz transmitter.

[@YourTechGuide.]

how you liking the phantom so far?

[@ghonis]

The Phantom was easy to learn to fly and I haven't crashed yet:)

[@stephenstrassen1135]

thanx so much great info and will help me a lot as i can see from others this is the best way to go.. personally id of put the antena facing to the back to give a little site of which way it is facing ie a tail by visual ha but that me. will be doing this once i get mine. have you got any footage to show thanx again ..

[@CuriousKitchen]

Thanks for the awesome video. Would I be able to record and stream through GoPro at the same time with your modification? Thanks so much.

[@ghonis]

Hi Binesh, Good question. I don't know. I haven't tried to stream video live from the Hero 3 camera using the WiFi connection and at the same time use the FatShark goggles.

[@westr70]

Seriously well done DIY. Heck I could even understand it.

[@jackwhite7184]

I haven't yet bought my Phantom and am scoping out what peripherals to get. I'm definitely adding the Fat Shark Predator V2 FPV goggles to the list. This may be obvious to someone who already has the Phantom, but how does one control the camera for capturing videos and still photos while flying? Thanks!

[@ghonis]

Hi Jack, I have only been taking videos with my GoPro. I start the video before liftoff by pressing the start video button on the GoPro, and press the button to stop the video when it lands.

[@TheZankaloni]

Hello, I love your work. But can you please send us a link for each of the items you have used here? Cheers!

[@ghonis]

Sorry, KZbin doesn't allow links.

[@leaboy2]

Thanks for the video. Do you have any video showing the reduction in vibration using the stabilizer that you have installed? I was looking into using a gimbal, but if this stabilizer does a fairly decent job with smoothness, then that would save a few pennies. Thanks again for the video.

[@ghonis]

Sorry, I don't have a video showing the reduction in vibrations after installing the stabilizer.

[@bhouck1000]

Hi Gary. Very nice youtube on the fatshark and dji phantom. My question is,dies the fstshark system interfere with the dji,s radio control system. Im going with your setup when i get my stuff together. Thnx again Brian.

[@ghonis]

Hi Brian, The Fatshark Predator Goggles use a 5.8 GHz transmitter. The Phantom 1 uses a 2.4GHz Transmitter, so there is no interference. The Wi-Fi used on GoPro HERO cameras, also operates on 2.4GHz and may interfere with the transmitter, so most keep the GoPro's Wi-Fi turned off when operating the Phantom.

[@sdw48er]

Is your Phantom an FC40? That's what i have, and my remote transmits on 5.8. So i can't use that frequency for video. It so, what video frequency are you transmitting on? And can you supply a link to the kit you bought? So i can get the same setup. Thanks Gary

[@ghonis]

The Phantom I bought from B&H Photo is a DJI Phantom Quadcopter with GoPro Mount Version 1.1.1. You can do a search on their website using "DJQGPM".

[@NoPathsNeeded]

Kinda odd how a video titles how to install has 12 minutes of randomness before you even start to install. Regardless, the last 2 minutes were great. Thanks!

[@craigslaughter9284]

Hi Gary, Just saw your video. Very good. Just one question please. Is it possible to turn the recording off and on using the reciever while in flight? Id like to learn how to do that if possible.

[@ghonis]

Hi Craig. I don't know of a way to do that. I use a large card for the video and have video captured for the entire flight. I can then edit the video as needed.

[@mumforddale1]

so when you plug the phantom up the tx comes on when its pluged up?so when you dont want to fly fpv all i have to do is not plug it up right?

[@Canyon76]

Hi and thanks for this. Is it possible to fly with the 600TVL that comes with the FatShark as well as the GoPro using the 600TVL as the FatShark viewer to sort of fram the shot and then positioning the Phantom so the GoPro can take the photo? I'm thinking about just setting the GoPro to record and then fly... I'm also wondering if this particular setup would be capable on the Phantom 2 (as well as Vision without GoPro) with GoPro and just adding separate battery for the FatShark transmitter? Thanks.

[@ghonis]

Hi Airwolf, I think that would be possible. The 600TVL is certainly light enough. Maybe you can give it a try? I have no experience with the Phantom 2.

[@ahorafilm]

Hi Gary, where can I buy only the small power part at the end of the power cable ? please let me know . thanks Marco

[@ghonis]

Ahora Film Entertainment Hi Marco. I don't know.

[@SuperMontanamike]

Gary, Why can't all videos on youtube be like this? Well done! I'm assuming you're an engineer. By the way, you called the transmitter a transformer...without an obligatory correction via subtitles.....lol ;) Great Job!!

[@CuriousKitchen]

Gary, Is the loose wire in the Phantom the auxiliary wire you mentioned in the video? Thanks so much.

[@ghonis]

Hi Binesh, Yes, that is the wire. You can see a closeup at 11:32 in the video. Gary

[@BenHayat]

Wow Gary, what a nice and well done review. Very clear to the point. Thank you Sir! Question: The cable that goes from transmitter to GP, does it charge GP battery too? Or does the GP use it's own battery during flight?

[@ghonis]

Hi Ben, I don't know. I always keep a battery in the GoPro and what limits the flight time is the Phantom battery.

[@BenHayat]

Gary Honis Thanks!

[@1rtuft]

Great tutorial !!! One question, does the USB cable to the go pro power or charge the go pro ?

[@ghonis]

I know it doesn't power the GoPro. You still need to have the GoPro battery installed. I doubt if it charges the GoPro battery. The GoPro Hero 3 battery has a pretty long battery life at around 1 hour 40 minutes and the Hero 3+ lasts over two hours.

[@TheCessna153]

Hi Gary good video! My question is about the IOSD Mini,how do you use that with the go pro footage because the cable goes straight from the transmitter to the GoPro3,so the IOSD would have no involvment. Thanks

[@ghonis]

I have never installed the iOSD mini. My understanding is that the IOSD mini requires can-bus. On a Phantom 1 to get can-bus, you either have to install pmu-v2, or you install the phantom upgrade board. I'm waiting for a concise installation guide before adding OSD and there is not much room inside the Phantom 1.

[@TheCessna153]

Ok thanks,I have found a installation video for the P2.

[@scampaboy]

Hi great video I'm going to go and buy one of these now. Just a quick couple of questions, if you dont mind, the power supply cable that you bought how simple is it to make something the same? I live in a place thats hard to get any electrical deliveries customs is pain in the bum. If its not possible to make could you just solder direct to the auxiliary power cable and make it so that the tx is always connected non removable.

[@ghonis]

Hi Richard, Yes, you could just solder the power cable, but it is probably better to have the connector that is used for connecting to the transmitter.

[@scampaboy]

Gary Honis thanks !!!

[@aabhrprints]

Ho w s you think that could be possibly mounted on the new DJI inspire one? If at all?

[@ghonis]

I have no experience with the DJI Inspire One. You would need to ask Fat Shark.

[@ACLV100]

I am new to the FPV and noticed that you connected to the USB port of the Hero. I prefer the Sony Action cam. Will the USB port of that work too?

[@ghonis]

Sorry, I don't know. I am not familiar with the Sony Action cam.

[@stockriderman]

So, is it for flying only or would I be able to do fpv flying and recording video? What about FPV + time lapse photography setting?

[@ghonis]

The GoPro records the captured video to its micro SD card and at the same time transmits the video to the fatshark goggles. I set the GoPro to its 1440 resolution mode because it is in the 4:3 display ratio and displays better in the fatshark goggles than in the 16:9 1080 resolution. I don't know about time lapse photography while flying fpv with the googles, haven't tried that. I think the GoPro would need to be in video mode.

[@sdw48er]

Hi Gary my Phantom runs on 5.8 GHZ. What frenquency does your Fatshark goggles run on. I don't want to get any interference between the Phantom's transmitter and the video. Do you have any problem with that?

[@ghonis]

The Fatshark Predator Goggles use a 5.8 GHz transmitter. My Phantom 1 uses a 2.4GHz Transmitter, so there is no interference. The Wi-Fi used on GoPro HERO cameras, also operates on 2.4GHz and may interfere with the transmitter, so most keep the GoPro's Wi-Fi turned off when operating the Phantom.

[@VarietyandTruth]

What is the cable called that attaches from the go pro to the antenna giving the ability to live feed the go pro through vision goggles? You mentioned it was on the readymaderc website but I can't find the cable. Mini USB something

[@ghonis]

If you use "Hero 3 cable" and do a search on the readymaderc web site, the cable to connect the Hero 3 to the transmitter is the "GoPro HERO3 Camera Cable (ImmersionRC/FatShark Style)" cable.

[@VarietyandTruth]

Gary Honis I checked it out and found it, however, I cant find where they accept paypal. I've sinced search ebay and found one here: www.ebay.ca/itm/GoPro-Hero3-Camera-Cable-Immersion-FatShark-Fat-Shark-FPVPCHGPH3FSAV-/251378009454?pt=Radio_Control_Parts_Accessories&hash=item3a874c056e I am wondering why in the picture, one of the wires is not connected to the plug in component.. ?

[@KjetilGunnesmo]

Thank you for sharing, just what I needed! :D

[@MikeMorrisonMeteorologist]

Gary, I noticed that you didn't use the power filter connector. Is that filter necessary?

[@ghonis]

Hi Mike, No problems without using a power filter on the Phantom 1 so far. I've read that some installing power filters eventually removed them. I would think since DJI has designed the circuit board to provide the auxilliary power lead, that they have taken any filtering needed into account. If you had interference lines in your video, banding or dropouts, that may be the time to try a power filter. I have no experience with your Phantom 2 which uses a different battery, so keep that in mind.

[@VikDesai]

Awesome video. Does this also allow you to record from the gopro at the same time as fpv?

[@ghonis]

Hi Vik, Yes, The GoPro Hero 3 camera can record video to its microSD card at the same time that video is being transmitted to the FatShark Predator FPV goggles.

[@chandlerkennell870]

What size heat shrink wrap should I get?

[@scampaboy]

Also the other question, I have a go pro 4 is it possible to connect or would i be limited to the standard camera?

[@ghonis]

Hi Richard, I'm not familiar with the GoPro Hero 4 model, as I have the GoPro Hero 3.

[@snowbikemike420]

I have the Phantom 1 and I recently bought the Phantom 2 but to my dismay they have a new battery pack system. I haven't opened it yet, but do you believe there may be an auxiliary power cables on this model as well? I would love to run my Hero3+ with a gimbal attached as my FPV.

[@ghonis]

Hi Mike, I don't own a Phantom 2 but I did read on the HobbyKing discussion forum that the Phantom 2 has "2 aux power options". See message #4384 on page 293. Maybe you could ask there about their locations?

[@snowbikemike420]

I found an australian youtube video with the Phantom 2 attached to the Zen Muse gimbal and a GoPro Hero3+. He attaches a special cable to the Fat Shark transmitter from the video link of the gimbal inside the Phantom. The video link supplies the transmitter with both power and live video feed from the GoPro while recording to the sd card. I have yet to try this but I am searching for this cord.

[@CuriousKitchen]

That was a great instruction video. Thanks so much for putting it. I am a newbie on this whole UAV thing. Where did you purchase the Fat Shark? I googled it and there are so many places. Is there some place you recommend?

[@rezekd1]

I recommend you to buy it on HobbyKing. They have great prices for high quality when it comes to FPV set.

[@ghonis]

Hi Binesh, I bought the fatshark googles from GETFPV. They shipped the fatshark two days after I placed the order and provided USPS tracking information. Gary

[@CuriousKitchen]

Gary Honis Dejan Režek Thanks guys. I will check both websites.

[@CuriousKitchen]

Gary Honis I got myself a Fat Shark system from HobbyKing as you had suggested. It is pretty cool. Just want to ask one more question, do you know what't the range of Phantom before it loses communication with the controller? Thanks a bunch Gary.

[@etab83]

After watching ur video I opened the quad and was unable to locate that auxiliary power cable I have version 1.1

[@ghonis]

Sorry to hear about your missing auxiliary power cable. You can look at the slides in the video at 11:29 and 11:41 to be sure where it is connected. If you do a google search using "No aux power lead on my Phantom", you will find that some others have had that problem. You may want to contact the vendor or install wires on your own, but that may void the warranty.

[@MisterAntDawg]

Can you use the fatshark goggles live feed and film using the GoPro simultaneously?

[@ghonis]

Yes, the video is captured to the GoPro''s SD card while the fatshark goggles are being used.

[@josjo8574]

I LOVEE you video explanation, I have the last version Phantom this past Nov 2013, but somone said I can not use googles, can you please verify this??, I like to be able to use googles and take them off and use regular monitor if need to. Can you please help me on this ??? thanks a million.....

[@ghonis]

I don't own version 2 of the Phantom, but my understanding is that you can use Fatshark goggles and a Hero 3 camera if a cable is changed out. See the video at bestquadcopter. Having said that, I read of video interference problems with the "Vision" version of the Phantom 2 and the Fatshark goggles because they use the same frequency (5.8 GHz).

[@halloosin8]

Thank you, this was really helpful.

[@TheDobleEE]

Hello!. Does the goggles work with Dji Phantom 2??? Thanks for the info!

[@ghonis]

I don't own a Phantom 2. You should ask Fat Shark about how their googles are used with the Phantom 2.

[@IEnjoydebeer]

gary,, very good video.. no frills. I am thinking of getting the Teleporter goggles. Do you think it's worth the extra $80 to get the Predator's? I plan on using my Hero 3 or 3+ as my viewing camera anyways so the little included camera is not an issue for me.. thanks for any help. Danny

[@IEnjoydebeer]

btw, I'm not interested in Head tracking or anything very much more costly or techy… just wanna get in the "cockpit" hah… so it's about the resolution or "viewing experience" i'd get in either goggle.

[@ghonis]

Danny, I think the extra $80 for the predator is worth the extra video resolution (640X480) versus the teleporter at only 320X240.

[@IEnjoydebeer]

Gary Honis hey, i got my predator's in the mail!! as I'm new to all of this, could you give me any advice or detailed instruction on charging the fatshark battery. any tips on charging these LiPo batteries would be welcome.. so excited!!

[@IEnjoydebeer]

Gary Honis also,, any specific order to turn all this on? like the phantom.. transmitter first then copter second.

[@IEnjoydebeer]

Gary Honis update.. just plugged them in fresh out the box, found a channel that worked. I'm in my bedroom at nite w lights on… doesn't seem that sharp of picture… not sure if gonna be better in the daylight??

[@scole901]

does the gopro run on 2.4 or 5.8, what is the control frequency of the phantom, 5.8?

[@ghonis]

Both the Phantom 1 and Phantom 2 use 2.4 GHz for the transmitter frequency. The Phantom 2 Vision uses 5.8 GHz for the transmitter frequency. The Fatshark Predator Goggles come with a 5.8 GHz transmitter so there is no interference with the 2.4GHz frequency of the Phantom 1 transmitter. The WiFi used on the GoPro Hero cameras operates on 2.4 Ghz, so I keep the GoPro WiFi turned off when I use the Phantom 1.

[@jeffnekuza3679]

Will these work with the new phantom 2 vision plus ?

[@ghonis]

Hi Jeff. I don't know. I have no experience with the new Phantom 2 Vision Plus.

[@hackyou360]

250 MegaWatt would be kinda heavy shit, you could fly away forever not losing the video signal hahaha :D Very informative video though as I bought a phantom this week second hand and the predator kit - it helped me out alot getting started :)

[@blakeflannery7973]

What is the price on all the products and can I use a tablet instead of the goggles

[@ghonis]

Hi Blake. This is what I paid: DJI Phantom from B&H: $479 Hero 3 GoPro from Rocky Mtn. : $330 Fatshark Predator V2 kit from GetFPV: $280 3 cables from ReadyMadeRC: $15 I don't know if you could use a tablet. I use a 7" monitor connected to the video out of the Fatshark.

[@baileymoto]

Which version Phantom (v1 or 2?) is this?

[@ghonis]

It is a version 1.

[@A3Kr0n]

Gary Honis It would probably work on both versions, right? DJI was nice enough to provide a cable dangling underneath my Phantom 2, and it sends the video through the Zemuse gimbal. Now I have an Airy Go Pro FPV cable I'll never use because I didn't know any better.

[@stevewainwright3344]

Unfortunatly, all the new phantoms have been switch to 5.8 on the transmitter So i would have to go with 2.4 i guess. Which limits what products you can use. Since most are running 5.8 on fpv It forces us new Phantom owners to go with a stationary sys. (meaning that i have to have a wire running to the goggles from a seperate reciever) Since all of Fatsharks wireless goggles run on 5.8.

[@MichaelPalmer70]

how do you tilt the camera while wearing the goggles?

[@ghonis]

Hi Michael, I don't have that capability since I do not have a gimbal installed.

[@MichaelPalmer70]

Gary, Thanks for the clarification!

[@dirtshower250]

Very well done!

[@jrgrey2000]

Very informative video thank you...

[@bhouck1000]

What happens to video signal when you bypass the power filter

[@ghonis]

I haven't had any video signal interference to date.

[@rittmaierbyron]

Will the gopro hero work with fatshark.

[@ghonis]

Hi Byron, The GoPro Hero budget model may work. I have no way to test since I don't own that model. The GoPro Hero budget model can not be removed from its protective case like the other GoPro models, so you would have to figure out a way to mount it on the quadcopter. The case has a back door that you would need to keep open for the USB cable connection, or maybe instead cut a hole through it.

[@35bigbri]

watt about the sj4000hd cable..?

[@ghonis]

Sorry, I don't know anything about the SJ4000 HD Camera.

[@35bigbri]

I want to yous my sj4000hd on my fatshark v2 googles need a cable..?

[@romanomm77]

About Range?

[@mumforddale1]

great vid i think im going to do the same bro thanks!

[@YasserButt]

very well explained!

[@howardjohnson9110]

I did enjoy it. Thank you

[@2cool0]

how much does this cost?

[@ghonis]

At this time you can still buy the Fat Shark Predator V2 googles for around $280 and Version 1 of the DJI Phantom is still available from B&H Photo for $479.

[@2cool0]

hmm nice....have you heard of the airdrop pocket drone? i wanted to get that too.....it's very similar to the dii but it is a lot more portable

[@salehalnabet8891]

Great work thank you

[@mumforddale1]

you dont have to take every thing off right?

[@ghonis]

Yes, you don't have to take everything off although using the velcro makes that easy to do. The Quad would be a little lighter that way. You don't even have to unplug the power wire to the transmitter, but doing that may allow the Phantom's battery to last a little longer. If you are not flying FPV, you could just leave everything connected.

[@Micp2912]

Gary, great video, very helpful, don't listen to the idiot comments on here. Do you like the fat shark model you picked or would you get something diff? Would you change anything if you could?

[@ghonis]

Hi Anthony, the Predator model is working well. When I bought it, I was interested in the DominatorHD because of its higher resolution, but I notice on the Fatshark website that it is still not available with an expected availability date of April 2014. If you are considering a Fatshark model, you may want to check future DominatorHD user reports before spending the extra money.

[@Micp2912]

Yea I'm trying to plan everything for my phantom Fpv before I buy anything. I was also looking at the dominatorhd. Is the resolution on yours good enough or would you spend the money for a hd? Right now I'm flying it stock w/ a 2mp cam but am excited about the upgrades. Im researching your setup with the addition of dragon link. Also trying to get views on the gopro black, if it's worth spending the money or just get the silver. Thank you for sharing, also what state do u you live in?

[@ghonis]

I am satisfied with the Predator goggles and don't have plans to upgrade to the DominatorHD model.....yet, anyway. If they were available at the time, I may have gone with the DominatorHD. The video graphics on my computer display are phenomenal with the higher resolutions of the black GoPro. The higher 1440P to 4K video resolutions are not avialable on the silver edition. TVs with the 4K resolution are now beginning to be sold. Going with the black edition would future proof your purchase if video resolution is important to you. I'm in PA.

[@mjones53]
