Steps of Constructing FPV Drone
Click on the hyperlink will take you to the part on this article:
1. Body Meeting
Earlier than constructing, it’s a good suggestion to arrange the body, though this step is non-obligatory:
- Sand down the sharp edges on carbon fibre items, notably on the outer aspect of the arms and plates. Sharp edges may reduce your wires and battery strap in a crash. Chamfered edges also can assist scale back the probability of carbon fibre sheet delamination in crashes.
- Wash all carbon fibre components in soapy water to take away any remaining carbon mud from chopping, drilling, and sanding (understand that carbon fibre is conductive). Then, dry the components completely with a towel.
To assemble the body, begin by positioning the arms and arm lock on prime of the entrance backside plate.
Subsequent, place the rear backside plate (which has push nuts) on prime of the arms, and fasten it with screws from the underside. Lastly, set up the eight aluminium standoffs, however be conscious of their totally different heights – the 4 entrance standoffs are longer.
2. Putting in Motors
Now, it’s time to mount the 4 motors to the arms. It’s advisable to make use of threadlock on the motor screws, as vibrations from the motors may cause screws to loosen over time. Luckily, the screws that include the Xing2 motors have already got threadlock utilized, so there’s no want for added utility.
The arms are 6mm thick, making the 8mm screws the right size. There’s no want to make use of washers.
Should you’re utilizing strange screws, make sure to get some Loctite (thread locker). Go for the blue liquid kind, because the pink liquid kind is designed for everlasting use and may make eradicating the screws later fairly troublesome.
Lastly, make sure the motor screws aren’t too lengthy and touching the motor winding. Should you’re unsure in regards to the screw size, observe this information on easy methods to verify in case your motor screws are too lengthy.
3. Wiring Diagrams
Earlier than continuing, it’s a good suggestion to create a wiring diagram on a chunk of paper outlining easy methods to join all of the parts. Should you’re utilizing the parts I advisable, listed below are connection diagrams you possibly can observe.
For the Analog construct:
For the DJI construct:
Earlier than soldering any wires, you possibly can “dry match” all of the parts within the body. This course of means that you can gauge wire lengths, decide element placement, and establish any potential spacing points.
Analog construct:
DJI construct:
4. Putting in ESC
Start by changing the 4 shorter screws within the body with the lengthy M3 30mm bolts that include the Speedybee F405 V3 stack. Keep away from utilizing nylon standoffs for putting in FC, ESC and VTX, they break simply in crashes. Use steel bolts as a substitute.
Use steel bolts for putting in stack (with a steel nut on the botttom), it reduces vibration and wobble, makes the drone fly higher and simpler to tune.
Slide the 4in1 ESC and FC boards onto the 4 lengthy screws, guaranteeing the ESC board’s energy pads face backward and the motor solder pads face up. The entrance of the body is identifiable by the cut-outs for the digital camera mounting plates.
Examine the underside of the ESC to make sure it’s not touching the body. Moreover, verify for any contact between the ESC and FC.
Subsequent, you’ll do some soldering. Should you’re new to soldering, consult with the tutorial “Tips on how to Solder for Learners“.
Decide the required motor wire lengths, leaving a bit slack, and reduce them accordingly. Safe the motor wires on the arms with material tape or electrical tape.
Some individuals like to make use of braided mesh tubes over the motor wires for cover/aesthetics functions. Personally I don’t use them, they’re a ache to put in and so they don’t actually present a lot safety or advantages.
Then, strip about 2mm off the tip of the wires and tin the ends.
Utilizing the trimmed off motor wires, solder two of them to the enter energy of the ESC (ideally on the underside aspect). Mark the constructive wires with a chunk of tape to solder the capacitor to later. You may also use any 20AWG or 22AWG silicone electrical wires.
Tin all of the solder pads on the 4in1 ESC. To forestall solder from by chance dropping onto the parts and inflicting electrical shorts, cowl the areas of the board the place you’re not soldering with tape, equivalent to electrical tape, kapton tape, or masking tape.
Solder the motor wires onto the ESC. Don’t fear about wire order and motor course but; you possibly can change this later within the software program. When you’ve got the talents, you may attempt to solder motor wires aspect means, make it nicer to seize the quad.
Solder the XT60 energy result in the ability pads on the ESC, ensuring to take care of the proper polarity (constructive and unfavorable). This step could also be difficult because of the quantity of warmth required to soften the solder on the massive copper pads. Be affected person and use the next temperature in your iron.
Soldering Ideas:
- Use a superb quantity of solder and solder flux (solder paste) for the massive pads, guaranteeing the solder joints are shiny and full. Should you can see the wire strands, you haven’t utilized sufficient solder.
- Apply extra flux if the solder “sticks” to the tip if you take away it from the joint.
- Be at liberty to make use of a excessive temperature when soldering massive solder pads, however be fast and keep away from overheating the pads for too lengthy. Use 450°C (840°F) for motor wires and XT60, and 380°C for sign wires.
Now solder the 1500uF capacitor that comes with the Speedybee stack. Bend and shorten the legs with pliers, then tin them with solder.
Apply a small piece of double-sided tape to the underside of the capacitor.
Solder the capacitor to the wires related to the ESC energy pads earlier, being conscious of the polarity. The aspect with yellow marking is the unfavorable aspect of the capacitor.
A capacitor is used to cut back voltage spikes and electrical noise generated by the ESC and motors. It could actually additionally assist when bent props create extra noise. To study extra about why including an additional capacitor to FPV drones is helpful, see this submit.
Lastly, join the FC to the ESC utilizing the offered 8-pin ribbon cable. When putting in the flight controller on prime of the 4in1 ESC, make sure the arrow on the FC factors ahead.
5. Testing ESC and Motors
Earlier than plugging in a LiPo battery for the primary time, guarantee there are not any electrical shorts. Utilizing a multimeter in continuity mode, take a look at the constructive and unfavorable terminals of the XT60 (or straight on the solder pads). If there’s a brief circuit, the multimeter will beep constantly. On this case, don’t plug within the battery, as it might injury your parts. As a substitute, troubleshoot and repair the problem that’s inflicting the brief circuit.
For extra info on utilizing a multimeter to check your drone, try this tutorial.
Professional-Tip: A brief beep adopted by silence might happen when testing continuity attributable to capacitors charging. That is regular and shouldn’t trigger concern. So long as it stops beeping after a second or two you need to be wonderful.
Use a smoke stopper when plugging in a battery for the primary time. Whereas not obligatory, it’s a advisable funding to keep away from damaging parts.
Don’t set up propellers but. To check the motors, plug within the battery and join the USB cable to the flight controller. Within the Motors tab of the Betaflight Configurator, spin up the motors one after the other (transfer the slider to round 10%) and confirm if they’re spinning within the right course.
To reverse a motor spinning within the mistaken course, use the Betaflight Configurator (Motors tab) as defined right here.
Additionally ensure the spinning motor quantity matches the diagram, e.g. motor #1 is the rear proper, motor #2 is entrance proper and many others.
If the motor order is mistaken you must repair it utilizing the “Reorder Motors” device within the motors tab, and following the directions. You may also repair it utilizing CLI instructions nevertheless it’s much more sophisticated, simply use the device 🙂
Troubleshooting suggestions:
- If motors aren’t spinning, make sure the battery is related. And the ESC ought to beep as quickly as you plug within the battery. Be sure the ESC is related to the FC, and that the pin connections are right.
- If all motors spin apart from one, that exact ESC, motor, or the ESC sign from the FC could be defective. To troubleshoot, swap the non-functioning motor with a working one on the identical quad to find out if the problem lies with the ESC or motor.

6. Receiver Setup
To solder the RX to the FC, you’ll want your personal 28AWG or 30AWG wires, because the RP1 doesn’t include them: https://oscarliang.com/wires-connectors/
Mount the RX in entrance of the FC utilizing double-sided foam tape or a zipper tie. You may mount it wherever with sufficient house within the body.
It’s finest to maintain the highest of the FC away from any wires, keep away from operating wires on prime or subsequent to the gyro which may trigger vibration throughout flight.
Safe the RX antenna beneath the closest arm with zip ties and wrap the antenna wire with tape to forestall it from getting caught.
Bind the receiver to the radio (TX module) following the information on establishing ExpressLRS. Within the Betaflight configurator, apply these configurations:
- Go to the Ports tab and allow “Serial RX” for the UART related to the receiver (UART2 in our instance).
- Within the Receiver tab, choose “Serial (by way of UART)” in Receiver Mode and select “CRSF” in Serial Receiver Supplier.
After this, verify that the receiver is working correctly within the Receiver tab. The bars (channels) ought to transfer if you transfer the sticks on the radio. If the mistaken channels are responding, strive a unique Channel Map equivalent to “default (AETR)” or “TAER.”
Arrange at the very least two switches on the radio (directions) for arming and beeper. You may additionally desire a third change for flight mode (e.g., angle mode). Verify that these switches work within the Receiver tab, with AUX1 and AUX2 responding if you flip them.
For any questions, submit within the discussion board: https://intoFPV.com
7. Putting in Analog FPV Setup
This part is for the analog construct. Should you’re utilizing the DJI FPV system, skip to the following part.
Set up the digital camera between the aspect plates.
Place the digital camera contained in the body and reduce the digital camera wires to size. Twist the wires to maintain them tight.
Solder the digital camera wires to the FC: Crimson goes to 5V, black goes to GND, and yellow goes to CAM.
For putting in the VTX, think about simply utilizing double sided tape and zip tie, as a substitute of utilizing standoffs. It’s straightforward, safe and weight saving should you don’t care how your quad look and simply performing properly.
Apply double-sided foam tape to the underside of the VTX, guaranteeing that it covers any copper to forestall contact with the body when mounted.
Insert 2mm zip ties via the mounting holes and tighten. Concurrently tighten down the battery leads.
That is the way it seems from the underside of the body.
Solder the VTX cable to the FC and ensure it doesn’t dangle round.
Strap the VTX antenna to the standoff.
To setup the VTX in Betaflight, go to the Ports tab and, for the UART that you’ve related the IRC pad to, choose IRC Tramp beneath Peripherals.
Copy the VTX Desk snippet under into the CLI for the Speedybee TX800. This may allow you to vary VTX settings within the OSD menu.

8. Putting in DJI FPV Setup
Comply with these steps to put in the Runcam Hyperlink and Wasp digital camera within the DJI construct:
Mount the Wasp digital camera between the aspect plates and set up it contained in the body, much like the method within the analog construct.
Take the DJI Air Unit cable that comes with the FC, reduce the ends, and solder it to the Vista. Right here’s the pinout of the Vista:
You received’t join the SBUS and GND pads within the Vista, so reduce these two wires off within the cable.
Apply double-sided foam tape to the underside of the Runcam Hyperlink (Vista).
Optionally, run the digital camera cable beneath the 4-in-1 ESC board for a cleaner construct. You may disconnect the digital camera cable from the video transmitter if crucial.
Set up the Vista within the body utilizing 2mm zip ties (ideally 15mm or longer), and strap the VTX antenna to the standoff as proven:
With the intention to have OSD for displaying battery degree and different flight info on display screen, you must configure Betaflight.
To configure Betaflight for OSD (on-screen show) to point out battery degree and different flight info. This web page explains easy methods to do it intimately. To sum it up, in Betaflight configurator, you must:
- In Ports tab, UART1 allow “Configuration/MSP“
- In Configuration tab, beneath Different Options, allow OSD
- Inside your DJI Goggles, go to Settings, Show and activate Customized OSD
That’s it!
As a last verify, energy the drone from a LiPo battery once more utilizing a smoke stopper to make sure all the things works correctly earlier than transferring on to the following step.
9. Ending Off
To finish your drone construct, observe these steps.
Safe FC with nylon nuts, fasten together with your fingers to keep away from over-tightening, they need to simply contact the rubber grommet. Compressed grommets scale back vibration damping and defeat the aim of sentimental mounting.
Strap the capacitor to the digital camera plates utilizing a zipper tie.
Set up the highest plate and thread a battery strap beneath and thru it. The Supply One V5 comes with a rubbery battery pad that works properly, however should you favor a top-notch possibility, think about the Ummagrip battery pad. It’s sticky, washable, and its thickness retains your battery safely away from the bolts.
The weights of the completed drone are as follows:
- Drone: 360g
- Drone + 6S 1100mAh LiPo: 560g
- Drone + 6S 1100mAh LiPo + GoPro 7: 680g
That is truly actually gentle for a 5inch and that ensures nice flight efficiency. As a rule of thumb, keep away from exceeding 750g with a 5inch together with battery and gopro in any other case it flies like a tank and don’t really feel good for freestyle.
When putting in the propellers, take note of the totally different rotations—CW (clockwise) and CCW (counter-clockwise). Guarantee they’re put in on the proper motors; in any other case, your quad might not take off or may flip over when attempting to.
Use M5 nylon lock nuts to carry the propellers securely on the motor. Tightening could be difficult at first however will turn into simpler over time. Keep away from overtightening to forestall prop hub shattering. Tighten simply sufficient so the prop can’t transfer if you attempt to rotate it together with your hand whereas holding the motor bell.
A devoted prop nut device can velocity up prop modifications.
When mounting the battery (and GoPro), make sure the COG (heart of gravity) is as near the drone’s heart as doable. To verify if the battery is positioned appropriately, seize the center of the highest plate with two fingers and see if the quad stays degree.
It’s important to take care of the COG on the heart of the 4 motors. If the quad is front-heavy, the entrance motors will work more durable than the rear motors to take care of a degree place, negatively impacting flight efficiency.
And we’re prepared for a take a look at flight!
Right here’s the DJI construct:
10. Utilizing 3D Printed Elements
For a cleaner, sleeker, and extra sturdy construct, think about using 3D printed components. You could find numerous designs on-line by looking for “Supply One V5” on Thingiverse.com. Elements for different frames may additionally work on the Supply One. One advisable supply for 3D printed components is https://3dprintsfpv.co.uk/. Should you can’t discover the components you need of their store, ship them a message with the Thingiverse hyperlink and the filament shade you need, I’m certain they’re glad to assist.
Listed below are some good ones I discovered:
One of the crucial fast and visually obvious modifications I like to recommend is the addition of 3D printed arm protectors. These will not be simply ornamental; they serve a vital position in preserving the integrity of the carbon fiber arms. With out them, the arms are susceptible to splintering on the ends upon influence. The great thing about 3D printed arm protectors lies of their capacity to soak up and distribute shock, considerably decreasing the danger of injury.
Additionally they shield the motors throughout crashes. These guards can forestall bending of the motor shafts and shield the motor bells from dents and scratches, which might have an effect on efficiency.
To make use of arm guards, chances are you’ll want longer motor screws, equivalent to M3 10mm.
Within the analog construct, utilizing a 3D printed antenna mount means that you can make the most of the MMCX to SMA extension cable that comes with the TX800 and improve the VTX antenna to a round polarized one for higher sign high quality.
3D printed components may also be used to mount the digital camera and capacitor.
The DJI construct with 3D printed components presents an improved look:
A 3D printed mount holds the Vista antenna at a extra optimum angle for flying.
11. Setting Up Betaflight
