One of the hot toys this Christmas was quadcopter drones. They are an awful lot of fun for a great price, and are a lot more fun to learn to fly than larger (more expensive to crash) models.

You are watching: One propeller not working on drone

If you are having recurring troubles through broken or bent props, prop guards deserve to aid.

Due to their inexpensive building and construction and very inknowledgeable pilots, tbelow are bound to be some breakdowns. In this tutorial I will describe how to relocation stripped screws, damaged or bent propellers, repair broken LEDs, damaged clasps, broken wires, and sheight the battery from shorting out the gyroscope.

If your quadcopter if flying unstably, making buzzing noises, not totally lighting up, not charging, flying via a mind of its own, one propeller is not spinning, it is loosing screws, or its shell will certainly not stay closed this is the instructable for you.

For this tutorial you will require:

- A collection of small Philips screw drives (my quadcopter forced a pH0)

- spare propellers (extras come with a lot of models)

- a hot glue gun

- clear tape

- a soldering iron and fine soldering tip

To open up your quadcopter, first rerelocate the 4 screws on the bottom of the situation, then remove the clips near each rotor.

Step 1: Bent Propellers


*
*

It is exceptionally common to bend the propellers of your quadcopter, bereason they are made to be soft as not to hurt civilization or cause damage to various other objects.

Bent propellers are defined by loss of lift from one propeller (if concave) or a buzzing sound similar to a mosquito and lessened performance (if convex).

Place your quadcopter on a flat surchallenge and observe the propellers at eye level. simply apply pressure to the propellers to bend them back right into shape. NOTE: Less is even more, repetitive bfinishing will sevedepend undermine the propellers leading to cracks or fractures.

Tip 2: Replace Broken Propellers

To replace a broken or sevedepend bent propeller sindicate pull vertically close to the center of the propeller then press the new propeller onto the shaft of the rotor.

Make certain that you replace the propeller with the correct replacement as tbelow are A and B propellers which turn in various directions to rise the stcapability of your quadcopter.

NOTE: Repeated removal and also replacement of the exact same propeller can cause the propeller to no much longer friction fit and also come loose during trip.

Step 3: Stop Battery Shorts

If one propeller no much longer spins, initially turn the quadcopter on and also turn it in different directions, the propeller which is greatest should slow down or sheight, if the propeller spins when it is the lowest, yet will not spin while level examine the insulation roughly the battery to check out if it is a shorting issue.

If the propeller will not spin at all check the wires connecting the motor to the circuit board. If one has actually become detached use a pair of forceps to host the wire and also usage a liberal amount of warm through a fine tipped soldering iron to melt the solder and also re attach the wire.

NOTE: just include solder if vital and make sure to usage fine grade "high tech" solder as it has a reduced melting temperature to avoid frying components and melting wires on compact circuit boards.

Tip 5: Replacing LED's

*
*

If one of the LED"s comes loose from your drone, the the majority of necessary action is finding the original LED bereason it is smaller sized than a grain of rice (around 1mm by 1.5mm). If you cannot discover the diode you have the right to buy micro LED"s for a couple of cents from commercial electronics stores.

Make certain to note the diode direction maremperors on the ago of the diode and the circuit board (make certain they point the same direction as soon as you area it on the board!)

You will certainly notice that if you place the diode once the motor is still in area it will be pulled in by the magnetic area of the brush-less motor, so the electric motors should be dropped.

Next off using a pair of forceps closely place the LED earlier onto the contacts then melt the solder with a fine tipped soldering iron.

After the solder has actually cooled make certain to revolve on the drone to test the LED"s before putting the situation earlier together as minor adjustments may be important.
