Excellent video, thank you very much!! We were able to bring my son's drone back to life after an accidental crash the day he got if for his birthday. Glue only lasted so long and now, thanks to your video, it has a brand new arm and it's as good as new again!
Offering a general comment to those that may benefit from this arm replacement in the future. After owning my 720E for several months and 20+ flights, the last two resulted in "fly-aways" and crashes, the final one resulted in a broken arm. In hindsight, I believe the prop had begun to loosen; it might have come completely off and resulted in the crash. My advice is to check your props to ensure they're well-fastened prior to each flight! Good luck to all, MP
I had mine go into point of interest mode after I press the go to home button. Ofcourse it crashed hard at full speed. I had it on low speed. I am wondering if its a phone issue can you tell me what type of phone you was using?
It was great to see how this repair was done as I have two broken arms. I can now do this repair in confidence myself. Thank you for creating video for all us do it yourselfers!
Good luck.
I appreciate this information. One part that was skipped is about 7:15 - 7:20. Putting the arm lock back on has to be done a very certain way for the spring hinges to work.
FYI, the replacement arm wire lengths should be the same length as the snipped wires on the old arm being replaced. Wire has weight and keeping the drone balanced in weight as per OEM would seem a good idea to me. This would allow you to forego unsoldering off the circuit board and just joining the new arms wires to the old wires still soldiered to the board. Confirming the weight of the drone both before and after the work to be the same would insure that the drone would be balanced to OEM. Thanks for a great video.
Can't say how much I appreciated your video. Gave me the confidence fix a broken arm myself.
Thank you for posting such a detailed video.
Great help. Tank you for explaining so easily to understand
Howdy, Brother! Just a quick thank you for sharing this valuable repair lesson. Fly-On, Cowboy!! 🤠
Great video! I appreciate the description of screw length and placement. Very helpful. Thank you!
Thanks again for the video
Thanks for the video. Exactly the information I needed and the same arm.
Thanks for this man, it really helps
Great video thanks for the help
Good job. Thank you.
What a relief! Thanks!
Thank you for doing the video, well well explained and easy to follow. Thanks again :-)
Great video thank you!! 👍🏼👍🏼
Fantastic video. Very helpful
Glad it was helpful!
My HS720 unexpectedly malfunctioned after just 2weeks. Didn't come in contact with any obstacles. I contacted Holy Stone and fortunately they sent me a brand new replacement.
Nice repair video. Hope mine doesn't malfunction again!
Nice. They seem to have good customer service.
Yes...thanks! Haven’t flown yet, but did contact Holy Stone with a question. Amazing service!!
Thanks for this. My new HS720E was flown less than 2 minutes before I had to kill the motor due to a mishap. It fell maybe 4 feet, and that was all it needed to break. I would return it, but I accept the fault. I'm chalking this up to a $300 learning experience. Thanks again.
thank u so much
Thank you for this video. I have a motor burnt up so I am just going to replace the whole arm with new motor. Thanks again...
Thank you!
Thank you for the video
You're welcome.
OK major major thank y for this fantastic video. Like you I crashed my drone and thought it was curtains. But after watching your video, I ordered the part and replaced the rear left arm did, all the soldering, took it outside, armed the rotors and bingo everything works perfectly. Again thank you for this clear, concise, and developmental video which is superior in its instructional value. We should all chip in and get you a present :-)
By the way, I was wrong down below in my comment. The wires on the new arm are already tinned and SO easy to solder!
Thank you. Glad it helped.
awesome vid thanks , just ordered my new rear arm and soldering kit
Good luck!
Thanks for this video. I had exactly the same problem, and followed your instructions. New arm is installed and working as good as new. Much appreciated
We’ll done. Glad it worked out.
This is an awesome tutorial. I had to replace the exact same leg on my 720 after I flew it into a tree. 😆 🤣 😂 I was very surprised to find it broken as well. Ordered a new leg from Amazon, watched this video & fixed it myself. Only thing I did different was ,I soldered the wires to the clipped wires instead of at the base of the board.... worked great! Thank you so much! I am a new sub to your channel..
Awesome video - was able to follow easily and replace our arm after a random fly away at full speed into a tree. Thanks for doing this!!
Glad it helped!
Thank you it worked well for me.
I bought one with a broken leg by coincidence was the same leg behind left.
I bought in the box a complet drone HS720E for 66.oo + 16.00 shipped a replacement leg from holy stone it took 2 weeks for the part arrive.
I am very happy with the outcome.
Once again thank you for the video.
Broke the arm off my drone filming a video in Miami. Thanks man.
Thanks for sharing. I can't put into words my frustration with youtube.
Great video thank you like you said the other video that was posted was just very fast
Thank you! Very helpful and informative, never have fixed something like this before! My replacement arm (same one you broke) comes in next week, I’ll let you know how it goes!
Good luck!
I used JB weld with metal Flight was great
thanks for this. broke an arm flying it inside the house the first day. lesson learned. glad i didn’t buy a mavic as my first drone
I hear ya.
Yeah this flying it in the house nonsense scares my wife and the cat and chops up all kinds of things including my hands!! No more indoors! ;-)
It's not your fault that you flew into the house, this is a drone, it drifts, does not hold the hovering point, can arbitrarily fly wherever he wants, does not have a pause button to instantly stop all movements in a difficult situation, turn off the GPS, and he will at least obey management. On Mavik, you would not crash into a house, especially on Evo Robotics, which hangs for half an hour at one point and can drift no more than half a meter.
you too huh? lol
Great tutorial. Thank you. Sucks about the crash tho.
thank you. after several months, I finally broke an arm. footage was great, bird was smooth and steady all day mostly tripod mode stuff. Switched to high speed holster flying. I misjudged by 10'. battery ejected upon impact, fortunately, it did not go into the lake. by about 2 feet !. I have 3 drones to repair now ! DE22 camera came loose, and HS700E motor needs to be checked after a hard land. time to order an arm !
Dang. Good luck with the repairs.
Good day sir thanks for sharing and how dis assimbly the drone dis s new friend thumbs. Great tutorial.
Great video, worked like a champ. The tricky part is getting all the wires stuffed back far enough that the case goes on and clicks in place. The nice thing about the design is the solder pads are big enough that you don't have to go through the hole to get a good joint and connection. Just bend the end and touch it. I bought a broken spare drone for par parts that now that I know I can do this, I will fix it and have an operational spare. Thanks!
Where does a person buy a broken drone for parts?
Thank You for this video it is better done than Holy Stone's and you had a better idea by leaving a small part of wire . Appreciate it. My crash was more violent I had a rotor explosion at 275 feet up ( it was not controllable) and despite my best efforts still end.ed up with a broken front arm. Yes I was lucky I did cut power.
Sorry to hear about your crash. Hope you can get it fixed. Good luck.
@@OurThrivingLife I could had avoided the problem if perhaps I did a more through preflight inspection , I also own a HS 720 2k and I have found micro cracks in the hubs due to cold weather flying. I have to use a Magnifying Glass with bright light to spot them. I bought 6 sets of Props so no big deal changing them and small price to pay for awesome winter Ariel Photos and video footage.
Mine got destroyed due to high wind against my home while inspecting my logs (log home). I did find a 3d print of the arm so It only cost about $1 to print out and worked quite good. Thanks for your video.
That’s awesome.
Thank you for a great tutorial of getting into the innards of a HS720E. Yesterday I had a bit of an accident with my drone and in the process damaged the mechanism which moves the camera gimbal through 90 degrees. I have been informed by Holystone that I may have disconnected one of the wire connecting the camera to the main board. The camera itself still works, so I’m crossing my fingers that the operation works, if you have any further suggestions please feel free in coming back to me. All advice and help will be gratefully received.
thank you for this. saved me from buying a whole new drone
Super video. All of them are. BUT please get closer to the mic. My volume is maxed out and you are off mic. When you went close up to demonstrate, it was perfect. Thanks!!
My left rear arm broke too... BUT in such a way that I was able to Crazy Glue it back. Will get a new one, but at least it flies for now. And yes... it could have been a 1300 dollar drone! ;-)
SUGGESTION: It is easier to get the wires to stick if you "tin" them first. OR you could splice them but then you''d need a band of electrical tape around each splice. Not sure if that weight would make a difference in flight dynamics.
W video
I believe I saw the video where it got destroyed.. Tough to watch!
How do you install the blades what order should the A & B blades be fitted???
The 720E and 720 are very different inside. You won't be soldering onto a board, you will be splicing wires together. If you own an E, you will see the difference when you open the drone up. Splicing is the easiest way and practically the only way to connect the wires on the E.
Thanks for the video. Husband got his stuck in a tree and it fell when he cut off the motors . Broke both arms on left side after the fall :( got the arms but he’s a little overwhelmed as last soldering fix project didn’t work out so we’ll with a computer chip. He’s thinking he needs flux and he’s afraid that he won’t solder right to make a good connection
Flux makes soldering a breeze
Nice video and well done. Have you also provided the soldering points with shrink tubing? Greets from Germany
Awesome video helped a ton! But I broke the same arm/leg as you did I replaced it but now it's pulling super hard that direction its actually unfly able. Did anyone else have this issue? #pleasehelp
Unless you have a huge open backyard it’s best to go to a park or large open area to get your first few flights in and get a feel for things… then by all means transition to your backyard.
It did have a crash and landed on the front props do you think its the motors or the board
Where can I find a replacement for the top cover of the HS720E body? Thanks!
where can i get hs720g replacement parts? amazon reviews say the ones the are selling on there do not fit the hs720g
My HS720e battery got stucked, I’ve tried to force it out and it’s not coming out, what did you suggest I do 😢
I just followed your video but replaced the arm one the other side, the one Holy Stone did on their video. I just finished everything and put it all together and now the drone just flashes red lights on all four arms. Did you or anyone experience this? Is there maybe a hard reset?
Awesome video well done ! Do you know if the front arms on a HS720 are the same as a HS720E ? Thanks
This repair is not for a beginner. The rear arms contain two longer black wires that have antennas attached to them. These wires are soldered to the board located under the brown looking glue at the back of the board. These are coaxial wires that have a ground and a positive connection on the board. Trying to splice these wires will only end in failure. You must strip them back far enough to re-solder them to the board in the exact location.
at 7:30 that back black wire is actually an antenna wire (coax) so it has 2 conductors...a braid ground and a center conductor. Did your drone work after you soldered those two all together???
Hey. Do you have a link for the arm on amazon please as I ordered the wrong one and it doesn't show pictures of the wires? Thanks :)
Like most on this thread, I greatly benefited from this vid and could practically 'smell' a successful repair. After attaching the arm and before soldering, I checked to determine if the arm would extend and retract properly. Dang it...nope it won't! It will move to both positions, but will not 'lock' in either! Anyone have a clue what the problem might be and how to fix? FYI, I got the new replacement, right rear arm from Amazon. Thanks in advance, Mike P
Hmmm. That’s odd. Are you positive that they sent you the correct arm?
@@OurThrivingLife BIG thanks for speedy response. I was deliberate when I ordered, but I'll have to confirm. I don't recall in the vid there was mention that the arm had to be in a specific position when attaching and inserting the pivot pin; and the plastic retainer seems to fit either way. I'll double check on these 3 possible corrections and update you. Might be a day or two; got a rough case of seasonal allergies!
Confirmed I orderly the correct arm; I successfully reattached it, but only after I held it in the extended or "open" position and inserted the pivot pin; then it operated correctly. Unfortunately, I can't get the drone to connect to the transmitter or "fly". The s. iron I had was only 35 watts and it took forever to reconnect the 7-wires. I may have overheated some of the adjacent circuit board or components and thus killed the whole dang thing! I'll trouble-shoot it a bit more. If it doesn't respond, I'll make a decision to either get a new 720E or a totally different drone. Hope I don't have to do that as I had a total or 3-batteries, and was satisfied w/ the HS. Win, lose or draw... BIG thanks for your vid and help!
I broke this drone and bought the DJI Mavic mini 2. Highly recommend the DJI
Never did see you attach the new arm into the body of the Drone
This is an expensive piece of plastic, which breaks if you blow on it! And when I looked inside there were a few torn threads - sloppy manufacturing - will never buy again far too fragile!! but great video thank you.
I agree with you. It breaks far too easily. It's a good little drone for the money, but not in the same class as Mavic or other more expensive drones.
I too will never buy another Holy Stone drone. BREAKS LIKE EGGSHELLS!!
@@OurThrivingLife Mine broke within a minute of first turning it on!
did u notice where the antennas are? it has 1 for 2.4 and 1 for 5ghz. I would like to know where they are so maybe i can improve with an add on :)
I notice my 720e has is on the back left arm when u open it
Hi do you onow if the hs720g arms fit the hs720e??
Sorry. I don’t know.
nice job i just broke mine and well the motor burnt out lol so i need another motor for the HS165 2K video, hey how long does ur flight last in the air with both battery’s mine does 20 With both batteries lol. 10 and 10 but i think it’s less lol
Mine will go about 15-20 mins. per battery,. Good luck with the repair.
Hello... Is there a way to reset the drone's controller please?its hs720g
Sorry. I don’t know.
I have a 720E. When I took it apart there was hot glue all over the soldering connections. I notice you did not dress this in the video. Did yours not have this ir had you already removed the glue?
same with mine
um do you have any alternative links for the spare drone parts? mine says it’s unavailable
Try this one: amzn.to/39S5mZo
Hi sir im Jason from the UK I have a hs720 also and have a question for you, would you know why a hs720 drone would want to flip forward all the time it won't hoover at all I try to take off and the drone just flips forward
That’s odd. I would reach out to Holy Stone. They have been good about replacing drones that don’t work properly.
How do you fix the motors inside the rotors? I crashed mine and now the rotors won’t operate?
You could replace the arm, which includes the motor.
Trying to order a new arm, should I look from the front where the camera is, or from behind, to know what is right or left?????
Looking down, and facing same direction as the drone, front is where camera is.
Mine also broke the same arm but at the base.
Bummer. These thing break way too easily.
Awesome job brother i did the same thing but it attack me cut my hands up wen i lifted it it came rt at me and i broke the the propeller motor i think not the arm
Attack of the killer drone!
Lol no doubt but they replaced it with a new one so all is good next time I'll stand a lil futher back but thank you for the great video and the Insight how to change out them arms great job love you videos I'll keep watching you got a fan here thank you have a blessed day
This is so helpful! The HS vid just went too quickly and did not have verbal instructions. This was great! This will be my first time to solder. I saw you were not having to use my solder, and we mostly able to use what was already there. When you did have to use some solder, were you using 63-37 tin lead rosin core? Do I need to buy flux? Any tips for soldering?
I mainly just used the solder that was already there. On one lead I used a little drop of solder, but no flux.
@@OurThrivingLife thank you for your reply. I’m hopeful it will work that way for me as well. I feel more confident now that I have seen your video.
@@OurThrivingLife did it end up working well after the fix?
@@spazchicken1 Yes. Worked fine.
@AMY ANDERSON Awesome.
Unfortunately this video is out of date. HS now coats the solder joints with a white polymer that is totally impervious to a soldering iron. So, look inside your drone before purchasing a replacement arm.
What do you think about shrink connectors instead of soldering? I'm leery of removing their welds and making my own. I don't know what else is soldered there or what is around it. You made it look super easy, but my skills may not be up to yours. Did you strip the insulation off the wires before soldering or, did the act of soldering "burn" off the insulation.
I love using shrink connectors.
Shrink connectors may not fit since there's so little room in there. I've got a 720E and hope I don't have to do this anytime soon
Please where did you order from?
Amazon.
Nice effort BUT you can see jack when it comes to the soldering. Anyone with no experience with electronics will be clueless as to the fix. Good luck!
Can the hs720 arm fit on the hs720e
Yes. Same arms.
Thank you very much
How did you solder the back long black wire? Mine has like a yellow glue on it and there is no where to solder to.
That sounds like the antenna. If so, it sticks out of one of the arms. It is just glued.
No it's the long black wire that goes in the back. Both rears have one. But mine have a yellow white covering on it. Like glue or some sort of shield covering the sauter. My long black wire was connected here and I just cut it at the glue. don't know how to solder the new one on though.
@@michaelkidd7821 Dang. That’s a tough one. It’s been a while since I did mine. Maybe someone who has done this recently can chime in.
@@michaelkidd7821 I have the same situation. The long black wire solder connection is covered by glue (insulation?). In addition, my daughter who has some experience with electronics says that that black wire is actually coaxial but in the video there is no accounting for soldering the inner and outer conductors. i.e. the black wire requires 2 solder point. That is a bit more complicated than shown in your video. I am picking off the glue to get a better look at it
@@brianwarner1165Yes you are right he did not mention the coaxial ,the outer braided wire is a ground
Im using a soldering tool and the wires cant connect
use flux
Hi i lost one of the screws that holds the arm in will it be OK with one screw ? If not what do i do ?
I would contact Holy Stone customer service. They’ll probably send you a couple extra screws.
Well, its a good video but my drone just decided to go off on its own and smash its arm. They sent me a replacement and it turns out I need to know how to solder now and own a soldering iron and, indeed, even find a screwdriver that's capable of not threading these screws. Suffice to say the "screwdriver that came with the drone" doesn't apply to me as none came! I just can't execute this and I'm surprised the company is actually directing me to this video to repair it. Pity. In the time that's passed I could have returned it and had it back by now.
Why did you make this video? Detailing last 5 years leading up to the crash? I got that! How about getting to the subject?
??
There are extremely toxic ads being played along with your video.
Instead of soldering, couldn't you just clip the wires on both sides, strip a healthy bit, wrap them around one another, and tape them with electrical tape instead of going in so deep and risk damaging everything by soldering?
That’s worth a try, but things are pretty tight in there. It might be tough to fit all the spliced wires.
I crashed my drone for the second time and one of my legs and wires broke so that one arms light not working when turning the drone on.
Dang. The do seem to break very easily. Hope you can get it fixed.
@@OurThrivingLife hey do they ever make any propeller protective guards for the hs720 drones? Because i looked through amazon and ebay for them and i do not see anything for the 720s but they have 700s types.
@@emorytraylor I have not been able to find any, either.
I am concerned as i do not have a soldering gun.
Don't buy them them ,,,
Did you make this video? Instead of detailing The Last 5 Years of your life leading up to the crash why not get to the subject?
Nice tutorial. I have a bad landing but the mechanics is working in fact o can control with the remote but the wifi is not working. Any idea if there is a module for the electronics circuit that I could replace? Or anything I can check?
I have a red light on the arm I replaced? customers remote is dead can't really test it, will see, update remote takes AA batteries, it flys fine though that arm light LED is Red pretty sure I wired it correctly, but what makes sense is that I soldered the small wires for the LED on backwards?
