Intro: How to Build a Cheap Quadcopter
Today I will teach you how to build a small, fast and super cool drone. It is super cheap and a fun project to build.
Step 1: Parts
Here are the parts you need:
- Tenergy 3.7v 380mAh battery
- Hubsan X4 H107 props
- Hubsan H107D coreless motors
- Hubsan H107-A34 receiver
- Materials for the frame (see next step)
- Charger for the Tenergy battery
- Transmitter compatible with the Hubsan receiver
- Zip ties
Step 2: Frame Possibilities
There are many possibilities for frame construction. You could make it out of cardboard or small plastic boards. As long as you can mount the motors onto the frame and have clearance, it's fine. My frame was about 6 inches long and 4 inches long at its widest points. There are all kinds of recommendations for quadcopter frames on the internet and even instructables, so I suggest do some research before you build. My frame weighed about 30 grams and balanced pretty well. Make sure your frame can balance at its center.
Step 3: Electronics Assembly
Here are the steps:
- Solder two motors of your choosing to the pads on the receiver labeled motor1 and motor3. The wires of the motors must be different colors, one has to be white and black and the other must be red and blue. Solder the positive lead to the pads labeled " +" and the negative to ones labeled " -".
- Repeat step 1 but solder a motor with different colored wires than the first motor on that side.
- Zip tie the receiver to the middle of the frame you built. I zip tied mine to the underside of the frame, but you can do what you'd like in that aspect.
- Zip tie the motors (like in the photos)to the sides of the frame and make sure they have total clearance of other parts.
You have now built a quadcopter. Bind the receiver to the transmitter and test it out. Now it's time for mods!
Step 4: Mods
I added a camera to my drone and purchased an FPV transmitter. With that particular receiver, there are some pads you can solder a camera module to. You can also add skids so the Quadcopter can land on water or a cage around your drone so it can fly up walls.
That's pretty much it. Thanks for reading and keep on making!
