After you finish this build, here’s a link to the setup guide. It has two important changes you should make to this build, so at least watch the first few minutes of it. https://youtu.be/WMDED6j1-Ic

Buy the Five33 Switchback and Motors at:
* Five33 (USA) – https://flyfive33.com
* Five33 (EU) – https://flyfive33.eu/

Buy the Aikon F7 Mini HD at:
* RaceDayQuads – https://bit.ly/3um4OCM
* Pyro-Drone – https://bit.ly/3ehUI09
* Catalyst Machineworks – https://bit.ly/33g8gmL
* Banggood – https://bit.ly/3um7Bfe

Pyro’s and CMW’s listing for the Aikon F7 is the V3 version. I use the V2 version in the video, and there are some slight differences between them–specifically the way the 5v/10v solder bridge works. I’m including the links to the V3 just in case the V2 is out of stock and you decide to go with the V3.

Buy the Redux Air 32 bit ESC at:
* Redux Air – https://bit.ly/3elWAF4
* ThrottleUpUSA – https://bit.ly/3tm60oo

There are allmost no dealers for the Redux at this time; and the Redux may be out of stock for a while. A good alternative is the Aikon 20mm ESC (bonus: you won’t have to make a custom wire harness to go between FC and ESC if you get the Aikon).

Buy the Aikon AK32 ESC at:
* GetFPV – https://bit.ly/3enRacZ
* Pyro-Drone – https://bit.ly/3nSzNDX
* RaceDayQuads – https://bit.ly/3um68Wg
* Catalyst Machineworks – https://bit.ly/3ek3gUo
* Banggood – https://bit.ly/3tjHuUV

CMW and RDQ links are to the 35A ESC. Other links are to the 50A or 55A ESC. Obviously, I suggest the higher rated ESC if it’s available.

    Those look like rebranded Tmotor IV gen ? Is that 1950kv?

  2. billybbob18 on May 21, 2021 at 2:55 am

    To access that difficult screw, use a low profile phillips wrench…. if one that thin exists; If not, create it…

  3. Mason Nelson on May 21, 2021 at 2:55 am

    Weird thumbnail, too much creepy face

  4. ExplodingEvo on May 21, 2021 at 2:55 am

    I just buy expensive stuff because I have problems I avoid by wasting money.

  5. Manuel Figliola on May 21, 2021 at 2:56 am

    Hey Josh, cool video, as always! Make small cut-outs in the battery pad to make the scews accessible! πŸ˜‰

  6. Patrick Boyle on May 21, 2021 at 2:56 am

    Josh! I know you get unwanted advice about how you build all the time, and I’m probably not even the first to mention this so I am sorry! When you are soldering at 21:33 you really should let the whole mass of solder come back up to temperature & become liquid again before you let off the heat. That seam between where it re-flowed and where it stayed solid is a cold joint and can crack.

    Love ya bud, I think you have the best drone content in the business

  7. no-trick-pony_lockpicking on May 21, 2021 at 2:56 am

    Thanks I learned that I want that friggin flux pin xD Didn’t think it would make that much difference! :O

  8. Rich fpv on May 21, 2021 at 2:57 am

    Flux is your best friend!

  9. Sascha on May 21, 2021 at 2:58 am

    Nice build Joshua, thx for sharing it! how about the weight of the drone, could you please tell us? thx!

  10. Anton Koba on May 21, 2021 at 3:03 am

    How about Predator Nano cameras?

  11. JohnnyD RC on May 21, 2021 at 3:03 am

    Hi Josh Great video on your own build, I have to admit I’m jealous. I just finished a build of my new 6s 4in. I really like this one you did , Maybe someday I will try out ghost, But until then I might just try out the frame. Can’t wait to see more video on this one.

  12. Kyle Fpv on May 21, 2021 at 3:04 am

    what is the best solder to use when building?

  13. Dan D on May 21, 2021 at 3:08 am

    Thanks for the endless help and information. I have a few soldering tips as someone who is JSTD-001ES certified. You shouldn’t need to add flux. The problem is that you tinned the ESC pads with too much solder. The extra solder creeped down the wires and also limited the amount of solder you could add during the actual soldering of the joint in order to avoid totally overfilling it . Not adding enough fresh solder is why you found you didn’t have enough flux from the solder and had to add flux. Tin the pads much thinner and you’ll find you won’t need to add flux and you won’t get the solder creeping down the wires.

  15. Stephen Gibb on May 21, 2021 at 3:10 am

    A lot of these new esc’s are coming out seem limited to 48khz to 96khz and unless the deadtime is much shorter also you surely are loosing motor braking performance.

    I feel like for best handling at extreme racing manoeuvres you want as much motor braking performance as possible.

  16. Wesley Wilson on May 21, 2021 at 3:12 am

    Can I just pay you to build one for me?

  17. J F on May 21, 2021 at 3:15 am

    What’s the dry weight for this build?

  18. Anno Fpv on May 21, 2021 at 3:15 am

    Any link for connector motor to esc?

  19. Ruben van Eupen on May 21, 2021 at 3:17 am

    What is the dry weight (quad without lipo and hd cam)? Also, what mah to choose if you go for 4s lipos?

  20. Ed Jmz on May 21, 2021 at 3:18 am

    Good building but you FORGOT to put Leds????

  21. jtcustomknives on May 21, 2021 at 3:19 am

    You know real quad builders soft mount their motors πŸ™„

  22. Howie Phuckterpusc on May 21, 2021 at 3:20 am

    what propellers do you recommend for this build tho ???????????? and what battery

  23. Samuel Armstrong on May 21, 2021 at 3:21 am

    49 dollars for a frame? What a deal πŸ™‚

  24. eddy current on May 21, 2021 at 3:24 am

    Soft mounted a cap brilliant

  25. N. Scott Stevens on May 21, 2021 at 3:25 am

    Counting the pins to be sure you have it right..,shit Joshua, you are just like the rest of us

  26. H2O- FPV on May 21, 2021 at 3:26 am

    It came out nice and if u need to change the direction of the motor now with m90 u dont need to dissolder just unplug and turn it and plug it again and that that cool.

  27. 4DCResinSmoker on May 21, 2021 at 3:28 am

    That MR-30 is pretty big. Would there be a smaller option?

  28. Henry Darr on May 21, 2021 at 3:29 am

    I’d cut the gummy to the shape of the base plate and drill apertures so I can see the screws with paint or thin cut tape to see if the screws are walking out.

  29. UDI Drone Racer FPV on May 21, 2021 at 3:29 am

    Good build, but the antena will not survive one day.

  30. N. Scott Stevens on May 21, 2021 at 3:30 am

    You aren’t special, you just love to build and fly like the rest of us

  31. Gabriel Pass on May 21, 2021 at 3:31 am

    What’s the weight of this build??? This looks sub 250g without a massive battery.
    Is that right?

  32. Michael Atkinson on May 21, 2021 at 3:32 am

    Wait, people _don’t_ like the red electrical tape? That’s an odd thing to complain about. I think it looks good! Also it’s your build, do what you want!

  33. Lucas Chapman on May 21, 2021 at 3:34 am

    anyone got a price out so i don’t have to?

  34. Petr Maliarov on May 21, 2021 at 3:35 am

    Hi! what is the weight of this drone?

  35. Chris Miller on May 21, 2021 at 3:35 am

    4:16 Yes, but does it come with red electrical tape??? πŸ™‚

  36. EnglishTurbines on May 21, 2021 at 3:36 am

    I saw you cut that Ghost antenna mount…πŸ˜³πŸ˜³πŸ˜³πŸ˜³πŸ˜―πŸ˜―πŸ˜―πŸ‡¬πŸ‡§….. Where’s my Fridge scene..?…lol..

  37. Alexander Rietz Vesterhauge on May 21, 2021 at 3:37 am

    Sure titanium screws are lightweight but can we talk about how disproportionately awesome they look in that red color????

  38. Michael Santoro on May 21, 2021 at 3:39 am

    Ur funny

  39. MrToralfen on May 21, 2021 at 3:39 am

    16:00 Haha:D

  40. JC FPV on May 21, 2021 at 3:41 am

    My BH 1507 3100kv runs absolutely beautiful on 3s but scream on 6s

  41. Taku Morrison on May 21, 2021 at 3:43 am

    JB … when is the video of you flying this build coming??? CHUUR!

  42. Joshua Bardwell on May 21, 2021 at 3:44 am

    Please! Watch the beginning of this video (https://youtu.be/WMDED6j1-Ic) to see two important changes you should make in this build.

  43. Caden Moore on May 21, 2021 at 3:47 am

    I have the bardwell f7 and I’m using Steele v3 2345kv motors for 5 inch, what 4in1 esc should I use? I was looking at the XROTOR 32bit, bardwell 4in1 (I question this one because it’s 30amps and was built for the f4), the succex 50 amp and aikon ak32. Which would be best?

  44. TailSpin RC on May 21, 2021 at 3:48 am

    Those MT30 plugs are so cool, new to me.

  45. Shaun Husain on May 21, 2021 at 3:48 am

    Hilarious intro…. relatable 🀣.

  46. modgod on May 21, 2021 at 3:49 am

    Man.. when you pin out upside down its so frustrating.. its the reason I prefer direct solder.

  47. Erik Jensen on May 21, 2021 at 3:50 am

    Hey, at least you got the screws to match the tape.

  48. ShuhDonk on May 21, 2021 at 3:51 am

    Which arm version did you use? SFG, Lite or Longback?

  49. eddy current on May 21, 2021 at 3:52 am

    if your running a fair race you have bad tactics
