Installation of wing support for the Xiaomi drone 1S: photo-instruction

Xiaomi drone FIMI X1S (often referred to as Xiaomi 1S) — It's a popular model for aerial photography because of its combination of price and functionality, but over time or after landings that fail, it may require replacing or installing wing support, a part that is responsible for rigidity and proper load distribution. This procedure seems simple, but errors here are fraught with vibrations in flight, unstable operation of the gyroscope or even the fall of the apparatus.

In this article, we will understand how to properly install wing support on Xiaomi. 1S, What tools are needed and what to look for when building, we will also look at the typical problems faced by owners when self-repairing, and give recommendations for balancing propellers after replacing parts.

If you’ve never disassembled a drone, don’t worry: design FIMI X1S It provides modular repair, and with a careful approach, even a beginner can cope in 30-40 minutes.

What is wing support and why should you change it?

Wing support (or arm support) is a plastic or carbon fiber part that connects the engine compartment to the drone's central body.

• 🔹 Stiffness of the design - prevents deformation of the frame during sharp maneuvers or gusts of wind.
• 🔹 Curbing vibrations – extinguishes vibrations from motors so that they are not transmitted to the camera and gyroscope.
• 🔹 Electrical wiring – motor power wires often pass inside the support, which simplifies installation.

Signs that it is time to replace the wing support:

• 🚨 Visible cracks or chips on parts (especially at the base).
• 🚨 Drone vibrates stronger than normal in flight, even after balancing propellers.
• 🚨 One of the engines is working with interruptions due to damage to the wiring inside the support.
• 🚨 The wing sags or luftitis when pressed with the hand.

⚠️ Warning: If the wing support is damaged but the drone is still flying, it doesn't mean that repairs can be delayed. Vibrations from a faulty part accelerate wear on the motor bearings and can disable the gyroscope.

The original support from the Xiaomi/FIMI and analogues from third-party manufacturers (for example, PGYTECH Original parts are more expensive, but guaranteed to fit in size and weight, which is critical for balancing the drone.

Required tools and materials

Prepare everything you need before you start, and even the absence of small tools can delay the process or damage parts.

Here's the full list:

• 🔧 Cross screwdriver (usually) PH0 or PH1 — depending on the screw model).
• 🔧 Tweezers for extracting small parts or wires.
• 🔧 Flat-dead (for fixing nuts, if they are in the design).
• 🔧 Insulation or shrinkage - for insulation of wires after repair.
• 🔧 Alcohol wipes – to clean contacts and surfaces before assembly.
• 🔧 Balancing plate (optional, but recommended for propeller inspection).
• 🔧 New wing support (original or compatible analogue).

If you are buying an analog, make sure it is compatible with the FIMI X1S. Some details from Xiaomi 4K or FIMI X8 may look similar but have different mounts or length of wires.

If you plan to solder wires (for example, when replacing the wiring inside the support), you will additionally need:

• 🔥 Stolen iron (power 30-40 W).
• 🔥 Solder and flux.
• 🔥 Thermo-air station (for thermal shrinkage).

⚠️ Warning: If you've never soldered microelectronics, you should trust this stage to a specialist. Poor soldering of the motor wires can lead to short circuits and failure. ESC-controller.

Step-by-step instructions for replacing wing support

Now, to the process itself, we'll look at the replacement using the right front wing (the algorithm is similar for the rest of us).

Step 1: Power outage and disassembly of the propeller

Before you start, make sure to remove the battery from the drone.

1. Remove the propeller by unscrewing the fixing nut (usually counterclockwise).
2. Put the propeller in a safe place so as not to damage the blades.

Step 2: Dismantling old support

The wing support is attached to the drone body with several screws. FIMI X1S They're usually 4-6:

1. Unscrew the screws that fix support to the central frame (they can be hidden under rubber plugs).
2. Carefully disconnect the power connector of the motor (it can be fixed by a latch - do not pull the wires!).
3. If the support is sitting tight, swing it from side to side a little to release the fixers.

Step 3: Transfer the wiring to new support

If new support is wireless, you need to transfer them from the old part:

1. Check the old wiring for damage, and if the insulation cracks, replace the wire.
2. Seal off the motor wires and ESC-Controller (if soldered) Remember or photograph the connection order!
3. Run the wires through the channels in the new support, observing the original trajectory (do not allow excesses).
4. Salt wires back using flux and minimal solder.

Step 4: Installation of new support

Now assemble the structure in reverse order:

1. Install new support in place, combining holes under the screws.
2. Connect the power connector of the motor (make sure that the latch is fixed).
3. Twirl the screws, but do not tighten them completely - first check the free stroke of the wing.
4. Install the propeller and slightly twist the nut (final puff will do after balancing).

Step 5: Mobility Checking and Balancing

After assembly:

1. Manually twist the propeller - it should rotate freely, without touching the body.
2. Check the wing backlash: if it wobbles, tighten the screws or add gaskets.
3. Use the balance plate to check the propeller (an imbalance of more than 0.5 g is unacceptable).

Common Mistakes and How to Avoid Them

Even experienced drone owners sometimes make mistakes when replacing wing support, and here are the most common ones and ways to prevent them:

Another common problem is getting dirt or metal shavings inside the engine during repairs, which can lead to jamming or overheating, to avoid this:

• 🧹 Work on a clean surface (it is better to cover the table with paper).
• 🧹 After soldering, remove the remains of flux alcohol.
• 🧹 Before the first inclusion, blow the engine with compressed air (for example, a canister for cleaning equipment).

💡

If after replacing the support drone "takes" aside during takeoff, perform calibration of the compass and accelerometer through the application FIMI Navi>. To do this, go to the Settings. → Additionally. → Calibration and follow the instructions on the screen.

Checking of performance after repair

Take your time to fly the drone right after assembly, and first, do some ground checks.

1. Visual examination

• 👀 Make sure all screws are tightened but not pulled over.
• 👀 Check that the wires are not clamped and do not touch moving parts.
• 👀 Inspect the propellers for cracks or chips.

Engine test

Connect the battery and start the motors at minimum speeds (via the remote or application):

• 🔊 Listen to the sound: it should be smooth, without creaking or extraneous noises.
• 🔊 Make sure all motors are rotating synchronously.
• 🔊 If one of the engines "twitches" - check the soldering of the wires.

3.Gyroscope and compass check

Turn on the drone and wait for the initialization of the systems. FIMI Navi check it out:

• 📱 No errors in the section The state of the drone.
• 📱 Correct readings of the compass (the shooter must respond to the turns of the drone).
• 📱 Lack of vibration warnings.

4. Test flight

If all previous checks have been passed, perform a short test flight at an altitude of 1-2 meters:

• ✈️ Check the stability of the freeze.
• ✈️ Make sure the drone doesn’t take you away.
• ✈️ Test sharp movements (for example, yaw left-right).

⚠️ Warning: If the drone is not behaving in a stable way, don't try to fix it in flight. Land the drone immediately and double check the assembly. Most often, the problem is incorrect balancing or poor wire contact.

💡

If the drone starts to consume more power after the support is replaced (the battery goes down faster), the reason may be increased friction in the engines, check the lubrication of the bearings or replace the propellers with lighter ones.

Where to buy original wing support for Xiaomi 1S

Original spare parts for FIMI X1S You can get it in a number of ways. Here are the proven options:

When buying analogues, pay attention to:

• 🛒 Material – carbon fiber is stronger than plastic, but more expensive.
• 🛒 Weight – the difference from the original should not exceed ±2 grams.
• 🛒 Set – in some sets there are screws and gaskets.

If you are buying a second-hand support, be sure to check:

• 🔍 No cracks (especially in places of attachment to the frame).
• 🔍 Integrity of screw thread.
• 🔍 Status of the wiring (if it comes in the set).

On AliExpress, look for original details on request:

• "FIMI X1S arm support original"
