    hi, i have question, i plug 3v buzzer but it sound very quet like ultrasound, i try buzzer with different battery`s and it sound loud, what is problem?

  2. tunedis95 on September 5, 2021 at 10:26 pm

    Sweet. Figure I would learn how to fly this toy before flying my FPV quad. I’ll be doing this same mod, including weight reduction. Add a go-pro, add a bigger battery, and balance impellers. Hope these little motors hold up. Should be a nice little setup

    Can You Mod The Battery ?

    You seem to use "soddering irons" over there. The rest of the world use soldering irons.

    The led on transmitter still flashing an not pairing with the quadcopter. Someone help me?

  6. Tony Grown on September 5, 2021 at 10:31 pm

    Perhaps measuring and cutting to proper wavelength? 2.4GHz figure mid bandwidth is 2.44Ghz so 1/2 wave 2.30 in. 1/4 wave 1.15 in. Use a bit of antenna theory here. Oorah!

  7. Tazgo84 on September 5, 2021 at 10:33 pm

    Thank you for the help the antenna I have is bad can’t get it more than 100ft but i will try your way… also I have notice the battery dose not last too long like 5 mins or less maybe can I improve it ?

  8. Canny Li on September 5, 2021 at 10:34 pm

    Good idea, let me got a lot to help production.There is a way to find lost machine, when you lost, turn off the remote control switch, then open again, when the machine with the remote control when they close to the code, will know that the attachment.

    Hi,

    I love your idea.

    I succeed changing the UDO 818A tx controller antenna. Watch here:

    Can I suggest a different way to get that buzzer feature? Search for "wireless 5 in 1 key finder". It’s probably sold everywhere under a whole load of brandnames. It consists of a 5 key handset and 5 key fobs. Disassemble a fob and inside you’ll find a teeny circuit board which includes a CR2032 battery and buzzer. Glue that inside the U8181A shell (it can easily carry this weight). The point is that now your buzzer has independant power, like a black box! In my case one common occurrence in a crash is that the main battery falls out, but with this method that won’t stop the buzzer from working – _and_ you don’t have to lose the LED on the nose.

    My U818a is coming in the mail today.  I plan to make these modes very soon after opening it.

  12. Martin Watson on September 5, 2021 at 10:37 pm

    i was wondering if you have a solution to my problem, the black wings wont spin to their full potential causing the front to flip back on itself and thus not fly. do you know whats the probkem?

  13. Jim Spruell on September 5, 2021 at 10:40 pm

    I did the receiver antenna extension and it really improved the control distance. I didn’t do it exactly like BubbleBeet, I ran the extension out front where the LED light wire used to be and then around the front of the frame to the side. I drilled small holes in frame to run the wire through.  If the wire is just dangling, it may get into the prop. The transmitting antenna length for the controller is very critical and is probably not worth the effort to fool with that.

  14. Joseph Gadberry on September 5, 2021 at 10:44 pm

    You can cut the rings off the cover and use the center piece only to protect the hub and wiring.

    Heres some new flight footage video with the mods installed, SUPER HIGH ALTITUDE and getting stuck in a tree multiple times.

  16. Viktor Božičević on September 5, 2021 at 10:44 pm

    Hi, can the extension wire for the range performance be soldered inside of the transmitter rather than quadcopter? And does this wire has to be the same gauge (thickness) or could be thinner? I’m not a professional in rc, but also have this quadcopter and would like to make a simple mod for more distant flying. Can someone please reply??

  17. smcfadden1992 on September 5, 2021 at 10:45 pm

    Have you ever flown it without the protective shell? If so is it any faster?

  18. Abhimanyu Kv on September 5, 2021 at 10:46 pm

    Bro that buzzer is headless mode

  19. Thunderstorm Parkour on September 5, 2021 at 10:49 pm

    upgrades for the drone’s camera??

  20. UrAvgRasian on September 5, 2021 at 10:50 pm

    Don’t use the stock micro sd card it’s too slow that why the video comes out choppy. I recommend Kingston or sandisk they can process faster giving you a smooth video.

  21. WarbirdPylonRacer on September 5, 2021 at 10:51 pm

    Doesn’t turning the lights off and on enable and disable headless mode?

  22. thedemonfoxnine on September 5, 2021 at 10:53 pm

    Hi I’ve got the udi u818a quad and I’m having problems getting it to link with the control? How or what can I do to get it to link together?

  23. ohhowhappygardener on September 5, 2021 at 10:57 pm

    That’s some pretty slick mods.

  24. Clyde Evans on September 5, 2021 at 10:58 pm

    I have extend my antenna on my Udi what’s good long range in my control extender antenna works good..🎮😆

  25. Travis Mobley on September 5, 2021 at 11:03 pm

    you do realize the shoulder button does more than control the lights right?

  26. Horacio Monterroso on September 5, 2021 at 11:04 pm

    As far as I can understand, adding the buzzer means losing one of the position lights. This is not a good idea

  27. Jeff Pharris on September 5, 2021 at 11:05 pm

    I have a UDI 1818A-1  & I could not get the buzzer mod (which is a great idea) to work, I have 3v buzzers but do not get any sound out of them when plugging it into either of the LED plugs. Any thoughts on the possible differences, almost acts like there is not enough current supplied on the board to power the buzzer.

    Thanks
    JP

  28. MIgardener on September 5, 2021 at 11:06 pm

    haha loved it! Things got trippy at 200 feet. 

  29. Joseph Gadberry on September 5, 2021 at 11:06 pm

    I don’t understand what the antenna length would have to do with the video.

    Hi, I’m a UDI 818a owner with a couple months experience. I have recently cut off the plastic, and what a difference it makes. I was wondering if any experienced RC guy can point to me a good book to learn and perform DIY and maintence. Thanks for the upload.

  32. Chicagoman36 on September 5, 2021 at 11:08 pm

    I want to upgrade my Camera on this to better pixel one hope they keep upgrading camera for this drone so we can upgrade camera only if we want

  33. Daniel Penton on September 5, 2021 at 11:10 pm

    Did the antenna mod after watching your video; WORKS GREAT! Much better range on the UAV and no interruptions in the videos now because it lost the signal. I was able to watch the full 12 minutes of flight time (3 minutes longer than average) without gaps. Thanks for the great tip.   question, why ebay versus amazon or for lack of a better example, why not Radio Shack for the buzzers? 3 weeks seems like a long time for buzzers, just curious. thx again

  34. T-Man on September 5, 2021 at 11:10 pm

    Im kinda scared to remove the prop guards though, im not that great at flying yet

  35. Jonathon Solway on September 5, 2021 at 11:13 pm

    Great video thanks for sharing tips with us 👍

  36. tim .413 on September 5, 2021 at 11:15 pm

    buzzer ye ok but antenna makes no difference yank

  37. Viktor Božičević on September 5, 2021 at 11:21 pm

    Hi, I unplugged red and blue LEDs from pcb and tried flying my UDI quadcopter without them and now when I want to plug them back, I forgot what are the corresponding sockets for each of the four connectors. Could you PLEASE send me photos or diagrams where to connect them?? My mail is: viki.bozicevic@gmail.com

  38. Nomadman on September 5, 2021 at 11:23 pm

    BubbleBeet
    Nice job! Thanks for taking your time and giving us Newbies some great ideas. Have you done anything on upgrading the battery? I saw one guy on YouTube remount the bottom leds and stick a 1200mAh 3.7v side to side. Looks like a perfect fit and he said he gets 2 x flight time. Thanks again
