Step 1: We Need a Frame....!

An important mechanical part of any drone is its frame. Everything including motors, battery, and circuitry are mounted on the frame.

Step 2: Make a Good Frame.

A well designed and balanced frame should be symmetric about its center of gravity and its center of gravity(CG), the center of mass (CM) and the center of symmetry should coincide.

The weight of the frame should be as low as possible.

To make a frame, I collected many plastic pieces from trash and selected the one with the lowest weight.

  • Cut the piece of plastic without breaking.
  • Draw the shape of the frame as per dimension.
  • Make four holes for the motors as per the dimension of the motors.
  • Cut and remove the unwanted parts.
  • File the frame to perfection.
  • Do some final finishing works like sanding and filing the edges.

Step 3: Get Some Motors and Propellers.

Now we need four motors and four propellers.

I shopped them online from eBay.in. You can buy this type of tiny motors for mini-drone from a local shop or from online platforms. And the propellers also.

The motor is rated at 3.7 V and it has high rpm.

The red or white wire is the positive one and the black one is negative.

Step 4: Put Everything Together.

Now we have the frame, motors, and the propellers. And we have to put everything together.

  • Connect the motors to the frame.
  • Stick the motor wires on the frame using small pieces of insulating tape as shown in the pictures.
  • Then stick a double-sided sticker to the middle of the frame to place the battery and the circuitry.

Step 5: First Test Flight.

Now the motors and the propellers are ready.

For the first flight, we need a 3.7 V 150 mAh battery also.

Then

  • Connect the positive wires of all the four motors together.
  • Connect the positive wires of all the four motors together.
  • Then connect the negative pin of the battery to the negative terminals of the motors.
