Holy Stone HS440 Replacement Parts: Available 2025!

Introduction

Crashed your HS440? Don’t panic – most parts are easily replaceable. The Holy Stone HS440 is one of the most popular budget drones out there.

It’s light, beginner-friendly, and fun to fly. But like every drone, accidents happen. Blades snap. Motors wear out.

Sometimes you just want an upgrade. That’s where Holy Stone HS440 Replacement Parts come in.

Having the right parts ready means you spend more time flying and less time waiting.

In this guide, I’ll walk you through the key parts you might need, why they matter, and how to keep your HS440 in top shape.

When To Buy A New Drone Instead?

Sometimes, fixing your drone again and again can cost more than buying a new one.

If you’ve replaced motors, batteries, propellers, and the body more than once, take a step back and do the math.

The total cost of keeping it alive might be close to what a new drone costs—or even more.

Plus, newer drones usually come with better cameras, stronger batteries, and updated features.

So if your HS440 feels like it’s spending more time on the workbench than in the air, it might be smarter to buy a new drone.

Trust me, sometimes starting new gives you more fun and less headache.

Holy Stone HS440 Replacement Parts Overview

Most Common Replacement Needs

When it comes to the most common replacement needs, I’ve seen the same pattern over and over.

Motor arms take the biggest hit — about 70% of repairs are because of them. A hard crash usually bends or cracks them. Next up are propellers.

Around 60% of users need new props at some point. They’re light, they spin fast, and they snap easily on impact. Then there’s the battery.

Even if you never crash, batteries start to lose power after 6 to 12 months. That’s just normal wear.

The difference is simple: crash damage happens suddenly. Wear damage happens slowly.

If your drone drifts, makes strange noises, or flight time drops fast, those are signs you need replacement parts.

Now here’s the big question — fix it or buy new? In my experience, small repairs like props or a motor are cheap and worth it.

A new HS440 is budget-friendly, but why replace the whole thing when a $10 fix gets you flying again?

I’ve saved hundreds over the years just by swapping out parts instead of buying new drones.

Complete Holy Stone HS440 Replacement Parts Guide

1. Holy Stone HS440 ARM Replacement

If you fly drones long enough, you’ll eventually deal with a broken motor arm. With the HS440, motor arms are one of the most common repairs. Why? Because every time you crash, the arms take the impact first. They hold the motors and propellers, so they carry the most stress. Don’t worry, though—replacing them is easier than you think. Let’s break it all down.

Types of Motor Arms

Your HS440 has four motor arms:

• Front Left Arm
• Front Right Arm
• Rear Left Arm
• Rear Right Arm

Each one is shaped slightly differently to fit the frame and wiring. So when you buy a replacement, make sure you get the correct side. Trust me, I once ordered the wrong arm and had to wait another two weeks—lesson learned.

Signs of Damage

How do you know if a motor arm needs replacing? Look for these signs:

• Wobbling or shaking during flight.
• Cracks or broken plastic after a crash.
• Loose motor connections that don’t sit tight anymore.
• Propeller tilting even when screwed in properly.

Sometimes the damage is obvious—a snapped arm. Other times, it’s more subtle. If your drone suddenly flies unevenly, check the arms first.

Step-by-Step Installation Guide

Alright, let’s get to the hands-on part. Replacing a motor arm takes around 20–30 minutes if you’re careful.

Tools You’ll Need:

• Small Phillips screwdriver
• Tweezers (for wires)
• Soldering kit (optional, if wires need re-attaching)
• Extra screws (just in case)

Safety Precautions:

• Remove the battery first. Always.
• Work on a clean table with good light.
• Keep screws in a small bowl so they don’t roll away.

2. Holy Stone HS440 Propeller Replacement

Propellers are the first thing to go when your drone takes a hit. They’re light, they spin fast, and even a tiny crack can throw your whole flight off. The good news? Propellers are cheap, easy to replace, and come in packs so you always have backups.

Understanding A & B Propellers

The HS440 uses two types of propellers:

• Type A: Spins clockwise.
• Type B: Spins counterclockwise.
• I recommend replacing the whole propeller kit.

Why does this matter? Because if you put the wrong type in the wrong spot, your drone won’t even lift off. Always check the markings on the propellers before installing. A little “A” or “B” is usually printed on them.

When to Replace Propellers?

Here’s how you know it’s time for new props:

• Cracks or chips on the blades.
• Bent edges after a crash.
• Strange vibrations or wobbling during flight.
• Shorter flight time because the props aren’t efficient anymore.

Even if the damage looks small, don’t ignore it. A cracked propeller can break mid-flight and cause a bigger crash.

Prop Guards (Bonus Protection)

• These are plastic rings that fit around your props.
• Great for beginners or indoor flying.

They won’t save your drone from a big crash, but they protect the props from small bumps.

Installation Guide

Replacing props is super simple. Here’s how I do it:

1. Remove Old Propellers

• Hold the motor arm steady.
• Unscrew the propeller carefully (check the direction—some are reverse threaded).
• Don’t force it. If it’s stuck, gently wiggle it off.

2. Install the New Propeller

• Match the “A” and “B” props to the correct motor arms.
• Place the propeller on the motor shaft.
• Tighten the screw, but don’t overdo it. Too tight can strip the plastic.

3. Balance Testing

• After replacing, give each prop a little spin by hand.
• They should move freely and stop smoothly.
• Do a short hover test indoors (low height) to check for wobble.

3. Holy Stone HS440 Battery Replacement

The battery is the heart of your HS440. Without it, your drone isn’t going anywhere. The HS440 uses a 7.4V lithium battery with a decent capacity for its size (about 1900mAh). It comes with a built-in connector that slides into the drone’s compartment, so swapping batteries is quick and simple. No messy wires, no confusion.

Signs of Battery Degradation

Even the best batteries don’t last forever. Over time, they wear out. Here are the most common signs:

• Shorter flight times – If your HS440 used to fly for 18–20 minutes but now struggles to hit 10, the battery is getting weak.
• Charging issues – Sometimes the battery won’t charge fully, or it takes way longer than usual.
• Swelling or physical damage – This one is serious. If the battery looks puffed up or damaged, stop using it right away. Flying with a swollen battery is dangerous.

Installation & Safety

Swapping the battery is simple. But handling it safely is very important. Lithium batteries can be dangerous if not treated right.

Proper Handling Procedures

• Always remove the battery before working on your drone.
• Never charge a damaged or swollen battery.
• Use the official charger or a high-quality compatible one.
• Never leave batteries charging overnight.

Installation Steps

• Power off the drone completely.
• Open the battery compartment on the back of the HS440.
• Slide the old battery out carefully.
• Insert the new battery until it clicks into place.
• Close the compartment securely.
• Test power-on to make sure everything connects properly.

That’s it—quick and simple.

Battery Care & Storage

Taking care of your batteries will make them last longer. Here’s how I do it:

• Don’t let the battery drain to 0% every time. Land your drone before it dies completely.
• Store batteries in a cool, dry place. Not in direct sunlight.
• If you’re not flying for weeks, keep them about 50% charged.
• Use a fireproof bag or box for storage—safety first.

4. Holy Stone HS440 Motor Replacement

If you’ve flown drones for a while, you know motors don’t last forever. They spin thousands of times per minute, take hits during crashes, and heat up fast. On the HS440, motors are pretty tough—but when they fail, your drone won’t fly straight (or sometimes won’t take off at all). The good news is, replacing them is totally doable at home.

Signs Your Motor Needs Replacing

Here’s how you know a motor is on its way out:

• One prop doesn’t spin or spins slower than the others.
• Weird grinding noise when flying.
• Overheating after just a short flight.
• Drone pulling to one side even when calibrated.

Sometimes it’s crash damage. Other times, it’s just wear. I had one motor burn out after a year of heavy weekend flying.

Types of Motors for HS440

The HS440 uses brushed motors. They’re affordable and easy to replace, but not as long-lasting as brushless motors on higher-end drones. You’ll need to make sure you get the correct motor for each arm, because the wiring can be slightly different (clockwise vs counterclockwise).

Step-by-Step Replacement Guide

• Remove the battery (safety first).
• Take off the propeller attached to the faulty motor.
• Unscrew the drone’s shell and open it carefully.
• Locate the bad motor—you’ll usually see burn marks or loose wiring.
• Desolder the old motor wires from the circuit board.
• Pull out the old motor from the arm housing.
• Insert the new motor into the slot, making sure the alignment matches.
• Solder the wires back onto the board (watch polarity: red to red, black to black).
• Reassemble the shell and tighten all screws.
• Attach the propeller and do a hover test.

Where to Buy Holy Stone HS440 Replacement Parts?

When it comes to buying Holy Stone HS440 replacement parts, you’ve got a few solid options.

The safest bet is always the official Holy Stone store or their Amazon listings. You’ll get genuine parts that fit perfectly and last longer.

If you’re looking to save a few bucks, you can also check eBay or AliExpress for third-party parts.

I’ve tried both—sometimes you score a good deal, sometimes the quality isn’t the best. My rule?

If it’s a critical part like motors or batteries, I stick to official. For small stuff like propellers or prop guards, I don’t mind going budget.

Either way, always check seller ratings and reviews before hitting buy.

Trust me, I’ve wasted money on cheap parts that broke after one flight—lesson learned.

Troubleshooting Common Issues

Alright, let’s talk about troubleshooting common issues with the Holy Stone HS440. Every drone pilot—new or experienced—runs into problems. Don’t worry, most of them are simple fixes. I’ve been flying for years, and trust me, I’ve seen it all. Here’s a quick guide in plain, easy words.

Drone Won’t Take Off

• Check the battery first. Is it fully charged and properly connected?
• Make sure the propellers are on the right way (A on A, B on B). Wrong placement = no lift.
• Calibrate the drone before flying. Sometimes it just needs a reset.

Drone Pulls to One Side

• This usually means a bent propeller or a weak motor.
• Try swapping the prop first—it’s the cheapest fix.
• If the problem stays, check the motor arm or motor itself.

Drone Shakes or Vibrates

• Propellers might be cracked or unbalanced. Replace them.
• Make sure screws on the motor arms are tight but not over-tightened.
• I once chased a vibration issue for weeks, and it turned out to be one tiny prop crack.

Short Flight Time

• Old or weak battery. Happens after 6–12 months.
• Flying in strong wind drains power faster.
• Try carrying an extra battery so you don’t cut flights short. I never fly with just one.

Camera Not Working

• Check if the camera cable is loose inside the shell.
• Sometimes a light crash knocks it out of place.
• If the lens looks blurry, clean it gently with a microfiber cloth.

Drone Won’t Connect to Remote

• Make sure both the remote and drone are fully charged.
• Turn on the drone first, then the remote.
• If it still won’t pair, reset the connection (check the manual for bind mode).

Maintenance Tips to Prevent Damage

1. Always Fly in Open Spaces

The number one reason for crashes? Obstacles. Trees, walls, wires—you name it. Give your drone room to breathe. Open parks or fields are perfect.

2. Check Propellers Before Every Flight

Props take the most beating. Even a small crack can cause a big crash. I always give them a quick look before flying. If one looks off, I replace it right away.

3. Keep Your Battery Healthy

Don’t drain it to 0% every time. Land before it dies completely. Charge with the official charger. And if you’re not flying for weeks, keep it half-charged. I’ve ruined good batteries by ignoring this.

4. Clean After Every Few Flights

Dust and dirt sneak into the motors and arms. Use a soft brush or canned air to clean. It takes 2 minutes and saves hours of repair later.

5. Calibrate Regularly

The HS440 flies best when it’s calibrated. Do it after a crash, or if it feels like it’s drifting. It keeps your flights smooth and stable.

6. Use Prop Guards Indoors

Flying indoors without guards is asking for trouble. Walls, fans, furniture—your props won’t last long. Guards are cheap, and they save you a lot of frustration.

7. Don’t Fly in Bad Weather

Even light wind makes small drones like the HS440 struggle. Rain? Forget it. I once thought “just a little drizzle won’t hurt”—and I ended up with a fried motor. Lesson learned.

Final Thoughts

The Holy Stone HS440 replacement parts are not just spare pieces. They’re what keep your drone alive and flying.

Over the years, I’ve fixed many drones—sometimes with a new motor, sometimes with fresh props, and sometimes just with a simple battery swap.

And every time, it felt like giving the drone a second life. If you love flying, keeping parts handy will save you stress.

But don’t forget—if fixing becomes too expensive, it might be time to grab a new drone.

Either way, the goal is the same: more time in the air and less time worrying on the ground.
