Want to learn how to build an FPV rig? This guide will walk you through your first FPV freestyle build. These parts were hand-picked to balance cost and maximize performance. The TBS Source One is a popular frame for it's low cost, high quality carbon fiber. It's easy to work with and provides more than enough space for your electronics. We've got a 32bit 4-in-1 ESC to bring you the smoothest flights and fewer solders as well as the popular TBS Unify video transmitter (VTX).

Tools

This build requires some soldering experience, but could also be a great way to practice. I highly recommend a flux pen, good 63/37 leaded solder and a quality soldering iron. Here are the tools and supplies you'll need. I've included direct links below in the part list.

  • Soldering iron
  • 2.0mm hex driver
  • Industrial Tweezers
  • Wire cutter/stripper
  • Scissors
  • Heat gun or lighter
  • Ruler and cutting mat
  • Multimeter

Additional Supplies

  • A variety of heat shrink tube sizes
  • Blue Loctite
  • Zip ties (small)
  • 63/37 leaded solder
  • Liquid soldering flux pen

Hardware

The frame kit and motors come with all the hardware you need, so you don't need to buy any additional hardware. I used blue countersunk washers and screws to add a little color, but those are entirely optional. What's great about a frame like this is you can embellish a little.

Frame Assembly

We're using the TBS Source One V3 which offers a couple new features over the V2, but most notably the arms mount below the base plate. This provides more space for the stack, but in our case we've got more than enough space. At least the battery strap won't rub against the components! The main thing to keep in mind is to orient the silver press nuts upward. Sandwich the arms with the small plate at the very bottom. Insert the screws upward and use the 4 tallest screws in the middle for the stack.

Alt TagAlt Tag

Motors

Alt Tag
Mounting the motors is pretty straightforward. Use the "For 4mm arms" screws and some blue Loctite to ensure they won't vibrate loose. I used some 1/4" Para-Max to sleeve the motor wires, but you can also secure the wires to the arms with electrical tape. If you do want to take that route you'll want to use some 14mm shrink tube to cover the ends of the sleeving.

Before you start soldering you should remove the flight controller from the 4-in-1 ESC to make it a little easier. Now I rotated the ESC board so the motor wires solder to the side and the battery tab points toward the back. This isn't the intended orientation, but I prefer to have my motor pads accessible. Plus you can add a capacitor and it'll be protected inside the frame. You'll need to paste some commands later during the Betaflight configuration to address the orientation change, but it's very easy to do and the commands are available below.

  1. Remove the nylon standoffs from the side you're soldering so you don't accidentally melt them.
  2. Flux and tin each motor pad ensuring each is completely coated with a bubble of solder.
    • These are pretty long pads so you'll want to push the solder back so it looks more like a loaf than a ball.
  3. If you're right-handed start from the rightmost motor pad and solder all 6 wires from right to left.
    • If you're left handed start from the left.
    • Cut each wire to length as you go, not all at once.
    • Take your time and press the wire into the solder slowly to avoid bridging the pads.
  4. If you used sleeving be sure to melt the shrink tube over the ends.

    Alt Tag

Power Connector

Alt Tag
Now it's time to solder the power lead. Unfortunately this stack doesn't come with an XT60 or wire, so you'll need to buy those separately. I took the opportunity to use all black. There's just something attractive about two black wires and a black XT60. Just make sure you've got the polarity correct!

  1. Solder the wires to the XT60 connector first and add shrink tube to cover the joints.
  2. Flux and add solder to the battery pads on the 4-in-1 ESC and solder the wires to the pads.
    • I soldered the wires to the pads horizontally, ignoring the vertical grooves.
    • Try to solder them so the battery lead points out toward the side of the quad. This will require cutting one wire slightly shorter than the other.
  3. Solder the capacitor on top of the battery leads.
    • The striped side of the capacitor is negative.
    • Make sure the capacitor angles upward so you've got room to mount the VTX behind the stack.

Binding the Receiver

Now that you've got power you can add the receiver and bind it. I used the FrSky XM+, but you'll need to choose a receiver that matches your radio.

  1. Solder 3 wires to the 5v, GND and SBUS pads on the receiver.
    • I borrowed some wire from the camera. It's got enough to spare.
  2. Solder these wires to the 5v, GND and R3 pads on the flight controller (FC).
    • Refer to the photo for wire placement.
  3. Add your flight controller to the stack and re-connect it to the 4-in-1 ESC with the included wire harness.
    • Make sure the arrow on the FC points forward.
  4. Bind your receiver
    • Be sure to double check that you don't have continuity between your main battery leads and use a smoke stopper if you have one.
    • Hold the bind button on the receiver while you plug the main battery in. (It's helpful to clamp this button down with tweezers to free your hand)
    • Put your radio into bind mode and make sure you're bound.
  5. Now that you're bound you can add some shrink tube to your receiver and put it in front of your flight controller.
  6. Attach small zip-ties to your front arms and shrink tube the antennas to the zip ties.
  7. Secure the flight controller with the included nylon nuts.

Camera

Next we can add the camera. First you'll want to screw the side plates to the camera and mount it onto the frame to measure the wire. Remove the purple wire and connect the wire harness to the back of the camera. Cut the wire giving yourself a little slack to adjust the camera angle. Refer to the photo for wire placement. "VI" stands for video input.

Alt Tag

Video Transmitter

Now for the last component, the VTX. Remove the 5V output and GND wires from the harness. We don't need those. We're using the FC to power the camera instead. This leaves just 4 wires. You'll want to use the B+ pad to power the VTX as well as the adjacent GND pad. Use "VO" for video output and use TX6 for the data wire. This allows you to control the VTX via your On-Screen-Display (OSD). Refer to the wiring diagram included with the TBS Unify transmitter.

Alt Tag

Camera Configuration

Now that you've wired the camera and VTX you can adjust your camera settings. Plug your quad in and check that you've got a video feed in your goggles. Then, plug the included camera joystick onto the connector behind your camera. Mainly all you want to do is disable the camera OSD. We'll be using the Betaflight OSD instead. Press and hold the up button to access the OSD menu. Disable each option and save.

Finishing Up

Now it's time to wrap it up! Screw the aluminum standoffs to the bottom plate and mount the top plate. Since I used countersunk washers I had to cut deeper grooves into the battery pad. Just make sure it lines up with the holes on the top plate. It's also a good idea to zip-tie the battery lead to the an aluminum standoff to reduce stress on your stack in the event of a battery ejection. Add your antenna and zip-tie it to the top plate, and finally you should zip-tie the motor wires to the arms to avoid snags.

Betaflight Configuration

If you don't already have them, you'll need to download Betaflight Configurator [Download] and the BLHeli_32 Configurator [Download].

  1. First go to the Firmware Flasher and choose "KAKUTEF4V2" as well as the latest stable release of Betaflight.
  2. Click "Load Firmware [Online]" and then "Flash Firmware" to update your flight controller. Once complete, click "Connect"
  3. On the Ports tab
    • On UART3 click Serial RX for your receiver.
    • On UART5 set the sensor input to "ESC".
    • Set the UART6 Peripherals to "VTX (SmartAudio)".
    • Click Save and Reboot
  4. On the Configuration tab
    • Under ESC/Motor Features select DSHOT600
    • If want to fly "props out" with reversed motors, select "Motor direction is reversed" below the illustration. (This is optional)
    • Under System configuration set PID loop frequency to 8 kHz.
    • Under Receiver choose your receiver mode. For the XM+ choose "Serial-based receiver" and "SBUS"
    • Under Arming set the Max arm angle to 180 (Only if you keep the accelerometer turned on)
    • Under Other Features enable: Airmode, OSD, ESC Sensor, Anti Gravity and Dynamic Filter
    • Under DSHOT Beacon Configuration enable RX set
    • Click Save and Reboot
  5. On the Power & Battery tab
    • Set the Current Meter Source to ESC Sensor
    • Set the Voltage Meter Battery Scale to 112.
  6. Go to the CLI tab and paste the following commands to map the motors:
resource MOTOR 1 A03
resource MOTOR 2 B00
resource MOTOR 3 A02
resource MOTOR 4 B01
save

To complete the remaining steps you'll need to apply lipo power to your build:

  1. On the Receiver tab ensure your pitch, roll, throttle and yaw are being applied correctly. Adjust your transmitter and Channel Map as needed.
    • I like to add about 4 or 5 to both deadbands to smooth out gimbal jitter.
  2. On the Modes tab
    • Assign an Aux switch to arm and disarm your quad.
    • Assign another Aux switch to enable Horizon or Angle mode if you need them.
    • Assign the Beeper and "Flip over after crash" to a 3rd and/or 4th switch. I like to assign them both to a single 3 point toggle switch with the beeper on the last position. Otherwise it'll beep when you don't have your radio on.
  3. On the Motors tab enable the motor test and apply a small amount power to check the rotation of each motor. Take note of any that need to be reversed.
  4. Disconnect from Betaflight Configurator and open BLHeli_32 Configurator
    • Connect and Read Settings
    • Reverse each ESC that needs to be reversed. This is done by un-selecting the other ESCs at the bottom and saving them one at a time.
    • Set the PWM Frequency to 48kHz of each ESC.
    • As an added bonus you can change the ESC startup music.
    • Reconnect to Betaflight Configurator to test the motor directions.
  5. On the OSD tab
    • Check all of the features you want and arrange your OSD as desired.

And that's it! The default Failsafe settings are generally fine, but make sure they work by arming your quad, applying a small amount of throttle and turning off your transmitter. It should shut down after a short moment.

Challenges

This was a really straightforward build. The soldering can be a slight challenge as the pads are pretty close together. Just take your time and apply flux when the solder starts to stick to your iron. To solder to the flight controller add a small ball of solder to the pad then push the wire straight down through the ball into the hole below. Lightly tug at each one to make sure you've got a solid connection. Other than that I had a hard time getting a nice clean ball of solder around the battery leads. I prefer square battery tabs, but these get the job done.

Maiden Flight

When installing your props make sure to pay attention to the rotation direction illustrated on the Configuration tab in Betaflight. If you're flying "props in" then the leading edges of each prop needs to rotate toward the front and rear of the quad. If you are flying "props out" then the leading edge need to rotate toward the sides of the quad. Make sure the lock nuts are tight but not extremely tight. Conduct your first hover test in a safe place where you won't damage anything or hurt yourself and then you should be ready to enjoy some FPV!

This is super cool build. Building this as my first quad (have cinewhoop). What Kv motors should i choose?

Whiffles   Sep 18, 2019

Depends on whether or not you want to fly 6S. If you just want to start on 4S then you can get the 2400kv motors. If you want to fly 6S then get the 1700kv.

Those are fine, I've got a couple myself.

wxlliam   30 days ago  

i used this build list as inspiration and changed a few things like the frame but have the same exact stack. how important amd what is the purpose of setting the esc in the uart menu. It flies great on easy throttle but when I begin to go to full throttle the quad immediately does something like a desync and falls out of the air, the FC remains on and im not sure how to troubleshoot it.

UPDATE: Replaced the esc and motors and now it is okay, so was most likely desync

kwadkenstine   26 days ago 

One of those things , Some motor esc fc combos just have issues . And here is the kicker , this can happen with any gear, even 2 esc of the same make , one will play one wont , i think it is because of accumulaited and compounding issues due to slack manufacturing tollerences in component spec, many of the components on even branded boards are recycled.

fpv.ba   5 days ago 

Thanks for the update! I'm glad that it's working now. I will get spare part just to avoid issues that you had.

mivo   16 days ago  

I'm working on my first ever build, modifying your initial setup accordingly to parts I have available.
Being not much fan of double sided tape, I'd like to put my VTX - a rush tank - on top of the existing ESC and FC stack. Is it a reccomended to do so?

Whiffles   15 days ago

As long as you've got space and it'll mount on the 30.5mm standoffs you should be good. Just make sure you've got a long enough antenna to reach the back.

This is a nice build. Just flew it for the first time (first drone ever). Was very straight forward to build, took a bit of figuring out BetaFlight and the X-Lite Pro, but nothing too terrible. Thanks for the clear instructions. Much apprecitated.

The one in the parts list:
FrSky XM+ SBUS Mini Receiver

Am I being terse and it actually is compatible with the Jumper T16? I know it uses the new ACCESS protocol which don't seem to be compatible with the Jumper T16?

Whiffles   17 days ago 
1

The XM+ uses D16, so it's fully compatible with the Jumper T16. I don't think FrSky is selling XM+ receivers with ACCESS pre-installed at this point in time. Try to bind using D16 on the Jumper.

Right you are. I'm such a n00b. Thanks binded right up. I guess I should have tried it first before asking questions :)

I'm sorry, I can't remember if it came with a capacitor or I just used one of my spares. It doesn't hurt to get a few spares just in case.

Gonna be my 3rd time building this on 4s. Lost my drone in the ocean again. It was doing fine the whole time until my last battery pack. i was hovering and it fell out the sky like it just failsafed on me. Any things that you would update on this build within the past couple months?

Whiffles   20 days ago 

Oh no! Did it say it was a failsafe on the FPV feed or did it just go to fuzz? You might want to check out the slammed Phreakstyle frame. It's very similar and has a slimmer profile.

Just completed this as my very first build following along with your video and very helpful guide.

Only thing I would have changed would be the vtx to the V2 non Race Edition as it provides a higher output for $5-10 extra bucks.
Not hard to replace now that I know how to solder but not something I absolutely need right now either.
I also ended up going with a Foxeer Falkor fpv cam as I accidently ordered a micro camera and I didn't want to wait until after Christmas to fly so I went with whatever Amazon could next day to me. Same for the antenna as Getfpv was sold out of the Thrasher antenna.

Only issues I had were with the VTX settings. OSD was showing blank for the Band: Channel: Power which the kind folks at 'FPV Builders' on FB groups helped me and had me Upload Fonts in the OSD tab of Betaflight.
That 1/2 fixed the problem as the B:C:P was now showing ?:?:? at which they pointed me to a Bardwell video on setting up the VTX Tables under the Video Transmitter tab. This got everything to work and I just got back from a test flight which was a success.

Thank you greatly for your write ups and as a fellow photographer, your amazing pictures as well!

I'm a little sorry for anyone else's gifts they give me for Christmas as this was by far the best gift I could have asked for :)

Whiffles   Dec 24, 2019 

Awesome! Thank you for the great report! Yeah, this guide was written before the VTX tables were released, so I need to update it to include that information. Be sure to post the build to the site so others can see your work!

Dose the 4 in 1 esc come with the capcitor?
thanks

King_MC55   Dec 09, 2019  

What lenght of countersunk screws did you use?

Whiffles   Dec 12, 2019 

I used 8mm but I suggest 10mm so they're less likely to fall out.

sadena22   Dec 08, 2019  

I just finished the build. Everything works but when I hover and hit about 50% throttle, it makes a very loud and notable noise. It kinda sounds like an angle grinder. I checked for loose components and made sure everything was secure. I'm thinking its the motors. Any suggestions?

alalaheyoo   Nov 20, 2019  

Built a replica of this but am having a problem. During flight the motors seems to just stop turning and the quad falls out of the sky. Maintains VTX signal and picture in goggles but sticks go dead. Any ideas why? How can I troubleshoot this?

The radio stays powered the entire time? I know my X9 Lite is picky about the batteries and sometimes they can lose contact and the radio loses power.

alalaheyoo   Nov 21, 2019 

yep, maintains power. ill keep messing with it

elliotfpv   Nov 23, 2019 

I've had this happen before with a loose connection between the FC and ESC. Different stack, but same style of ribbon cable connection between the two. Double check that both plugs on the cable are seated snugly. Sometimes a bit of electrical tape on the top of a plug can tighten up a loose connection.

RobertRC   Nov 15, 2019  

now I'm having trouble flashing the firmware.. keeps saying failed to open serial port. I've downloaded drivers n what not. it connects and powers up when I hook up to the computer. I have the firmware loaded also.

welp. it's all ready for the computer now!

RobertRC   Nov 12, 2019  

I'm a little confused on the soldering of the motor wires to the esc, theres 3 wires, does it not matter in what order I put them?

Whiffles   Nov 14, 2019 
1

It doesn't matter. You'll need to test the rotation of each motor during the configuration process and reverse any that don't spin the correct direction using the BLHeli32 configuration app. I prefer this to swapping wires around.

whiplash willy   Nov 06, 2019  

I was thinking about trying this as my first build, but have never tuned a quad before. Any advice on how to tune it, or could you post your PIDS?

Whiffles   Nov 14, 2019 

It depends on whether or not you build this for 6S. You should be fine on the stock PIDs flying 4S but for 6S they recommend lowering the P and D values by about 30%.

RobertRC   Nov 12, 2019  

what temp do I solder at?

Whiffles   Nov 14, 2019 

I use 700 degrees F.

hasan2007   Nov 12, 2019  

Hi Whiffles,
Would the Diatone mamba f722s be better than the kakute? What do you think?

Whiffles   Nov 14, 2019 

They are very comparable. While the Diatone has an F7 chip the advantages aren't very substantial. You should be fine either way.

ChrisDuhBest   Sep 21, 2019

Do I need to buy a pair of antennas for the video receiver listed?

Whiffles   Sep 21, 2019 
1

Yes, I recommend a couple circular polarized, omnidirectional antennas for the Rapidfire. Maybe something like the Strix Hoot.

RobertRC   Nov 02, 2019  

100% noob here as far as building one of these from scratch. I think i may attempt this one. I have a couple questions, if I leave the esc board as intended, what steps on your list would I ignore? and also, how would i go about strapping a go pro or other onto this?

Whiffles   Nov 04, 2019 

You'd just leave out the CLI resource commands, but I recommend rotating it like I did to make the USB port accessible.

Jax   Nov 03, 2019  

what powered screwdriver is that?

Whiffles   Nov 04, 2019 

That's the Xiaomi Wowstick 1F+

RobertRC   Nov 03, 2019  

also what kv do I get for the motors? currently 24 and 19 are out of

RobertRC   Nov 03, 2019

figured this one out and the go pro question lol..

alalaheyoo   Nov 01, 2019  

What part in beta flight addresses the FC not facing forward? What would happen if you tried to throttle up and didnt make the correction in betaflight? flipover?

Whiffles   Nov 01, 2019 

The resource commands in the Betaflight configuration section address the orientation.

alalaheyoo   Nov 01, 2019 

Sorry Im new to this. Thats when we enter the following in the CLI tab?
"resource MOTOR 1 A03
resource MOTOR 2 B00
resource MOTOR 3 A02
resource MOTOR 4 B01
save"

Whiffles   Nov 01, 2019 

Yes, without the quotes.

Thank you for your answer :)

alalaheyoo   Nov 01, 2019 

I did the same thing. Do i have to change anything under the PORTS tab? specifically UART6?

Whiffles   Nov 01, 2019 

As long as you wired to the same pad on the FC you should be fine.

Hi Sir. If i change the frame to Martian II.Does it still work with those components ? the camera ? props ? motors ? Thanks you sir

Whiffles   Oct 30, 2019 

It should work just fine.

What size are the countersunk M3 screws you used? 6mm?

I did use a capacitor on the main battery lead.

Iamhugo01   Oct 27, 2019 

what size cap do you reccomend ? and is one enough ? Thanks for your time bud!

Whiffles   Oct 29, 2019 

470uf is about standard for these and you generally just need the one on the battery lead.

Im new to building and dig what you put together here. Was trying to keep everything as close as possible to what you did with yours. Would you have a suggestion for a good substitute for the flight controller that I can still use with all the other components? I cant seem to find the one you used in stock anywhere. Thanks for sharing your build

How about the XILO Stax? That's a pretty comparable stack. You'll need to figure out the wiring but it should function nearly the same as the Kakute.

hey i just built literally the exact build except with a different vtx, cam and receiver, quick quesiton, whats your pid tune im having a rediculously herd time tuning mine

Is it 6S? All I really did was reduce my pitch and roll P and D terms by about 30% and it flies just fine. I haven't done anything other than that. I'm running BF 4.1

This is going to be my next build... genuine question, why are the props such an aggressive pitch for a freestyle rig? Wouldn't that take away from flight time and smoothness?

Whiffles   Oct 08, 2019

I mainly chose these for the color. Feel free to use any prop you're comfortable with.

Hey man, the FPV cam is out of stock do you recommend any others?

Whiffles   Oct 04, 2019

I really like the Caddx Ratel, but you'll need an adapter like this to mount it to the frame.

Hello Whiffles! First of all thank you fot the effort you've put into creating this build, I really like the aesthatic part. I'm a beginner and have only one question. There's a new version of Kakute FC which is F7 and costs almost as much: https://www.getfpv.com/holybro-kakute-f7-hdv-tekko32-f3-hdv-4in1-40a-esc-stack.html May I use it instead of the one you've listed or I'd have to change other parts for it to work? Thank you in advance!

Whiffles   Oct 04, 2019

Sure, that'll work just fine. You'll just need to learn the pin-out and rework the wiring accordingly.

Hi there,
what's the weight of the quad loaded with batteries ? (If you can provide with and without GoPro ? )
Thank you :)

Whiffles   Sep 21, 2019

The weights are in the build video. It's 386g bare and 750g AUW.

What do you think about those props?

Whiffles   Sep 14, 2019

So far so good! I'm not very sensitive to prop changes though, so I may not be the best person to ask.

JasonFPV0   Sep 14, 2019

Hm, interesting. I was using cyclone 5050's but then I tried Johnny props and they were a lot smoother but also decently less powerful. I'm hoping the azures will have a nice balance, and the other ones just look sweet.

hello, on the tbs unify pro hv it's mentioned to be wired directly to the lipo. is it ok to power it from a 5v source like you did? thanks

Whiffles   Sep 12, 2019

I wired it to the B+ pad which is direct power from the lipo.

As a complete absolute beginner, I have a few questions If anyone could answer I'd greatly appreciate it. I have been told to use the FRsky Qx7 Radio, which doesn't include a battery/charger. and even sourcing it to the cheapest places it would run around $150.00 after battery/charger/radio purchase. I was thinking I may as well buy a X9D for $200 that already comes with the charger/battery/radio? Is the X-lite pro a better option? And my bigger question is the difference between the "S" Is 4S fine for freestyle drone flight? What is the advantage to 6S? Longer flight times?. I'd like longer flight time without giving up performance. if possible... Also what about wiring? Is it good to have spare wire and at what guage do I want the wire, I have 100 other questions I'll probably end up asking eventually If i knew people in the community, but sadly I'm new and it's definitely a bit daunting to get into. I have some money to spend on the hobby though I'm not trying to spend an absurd amount. I was going to pick the Eachine EV200D's as a set of goggles to reduce my build cost down as well, could go with cheap box goggles but I have been told to avoid those. I also thought about just buying the radio/battery/charger and doing some sim flights whilst I figure out a build, but now im stuck deciding on the radio :/

Hi. Go the sim option. look into multi protocall radios like the jumper brand also use it for sim.
4s v6s . after you can fly pack after pack without crashing and smashing props every second flight, then 6s becomes viable, untill then spend the money not spent on 6s batts on props and repairs..
goggles I Can recomend skyzone , i have the 02x , aiomway commander and fatshark dom v4 .
All of these are good solid goggles , but i rank them as above.,
Wire is something that just seems to multiply in the corner all by its selfe once you start building.
hope this helps

I love the X-Lite. It's a great compact radio. You just need to keep in mind compatibility. The new X-Lite Pro and the X-Lite S use their newer ACCESS protocol. They still support ACCST D16 which covers about 90% of the quads out there, but there are still some that only support D8. For example the original EMAX Tinyhawk is only D8. You might also want to consider the X9 Lite. It's also an ACCESS radio, but a great value. Plus it takes 18650 batteries. It doesn't have an internal charger, but you can add an internal charger for a few dollars.

Between 4S and 6S the difference is very subtle. You'll generally be able to squeeze an extra 30-45 seconds of full power out of a 6S battery, but we've been using 4S for years without any issues. You just need to consider the battery cost. 6S packs have come down in price considerably over the past few months though. Also, if you build for 6S with 1700kv motors you generally don't want to use 4S batteries on such a low kv rating. Either you choose one or the other and stick with it for your entire fleet.

If you do this long enough you'll have enough spare wire to build several quads. You may want to buy some 16awg wire for the battery leads as that doesn't always come with the kits. Its better to invest in a wide variety of shrink tube, m2 and m3 screws.

As for the headset I'd look at the FatShark Recon V3. It's a great budget headset. It doesn't have all the features of the EV800D, but it's a high quality set and the optics are easier on the eyes IMO.

You should definitely invest in a radio first and start out on sims. Then you can graduate to a micro like the Tinyhawk S and ultimately end up at 5".

Turbotron9000   Aug 29, 2019  

Definitely going to be picking this one up, thanks! I see Brain3D has a GoPro Hero7 mount for this frame. Would you suggest that one, or something else?

Whiffles   Aug 29, 2019

If it's made for this frame then it should do the trick!

JUSTiFLY_FPV   Aug 28, 2019  

Is the paracord planet stuff what you used for your motor wire sheathing? On amazon it doesn't look hollow?
Please let me know, thanks.

That's it, just pull the threading out from inside.

stefun   Aug 24, 2019  

Nice build but I have a newbie question. Can I use this build with 4s batteries because I want to build it with DJI digital system? Does everything else remain the same?

Whiffles   Aug 24, 2019 

Sure, you can use 4S but make sure you get 2400kv motors rather than the 1700kv. I don't think the DJI system will fit though. It's pretty big.

Trashyfpv   Aug 23, 2019  

Does the Source One come with the battery pad?

Whiffles   Aug 23, 2019 

Yes! It's a nice bonus for the price.

any video of you flying

Whiffles   Aug 22, 2019 

Not yet, still need to take it out.

Piposch   Aug 22, 2019  

Hi
do you think this build would be possible with ah armattan rooster frame ?

Whiffles   Aug 22, 2019 

I believe that should work, but I'd double check the height of the stack against the stack space.

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
