Introduction: Bottle Cap Microquadcopter
Because I couldn't wait for the new body shell for the hubsan x4 to come, I had to have an alternative to fly!
So, after some hours thinking and trying several scrap objects, I finally found out that I could tight together 4 black paper clips and a part of a 5 liter water bottle. The clips clamp the 4 coreless motors. The flight controller it is protected by the botle tap. The leds are glued to the paper clips with hot glue.
Step 1: Remove Components From Crashed Hubsan
Unscrew 3 screws to remove the cover.
Take a photo of the bottom of the flight controller.
Unsolder the motors.
Remove the feet of hubsan.
You should be able to get off all the parts after this steps.
Step 2: Remove the Grip Part of the 5 Liter Water Bottle. You May Use a Sharp Nife. Be Aware to Not Cut Your Self. the Part You Have to Save Is the Part That Holds the Grip to the Bottle
Step 3: Attach the Motors to the Paper Clips.
Open the clips and grip the motors.
You have to do it otherwise it will be a bit difficult to attach the the tap grip.
Step 4: Remove the Paper Clip Metallic Parts
You have to do it to attach to the bottle tap grip.
Step 5: Attach the Paper Clips to the Bottle Tap Grip
Should be something like the picture but without the flight controller
Step 6: Solder Back the Motors to the Flight Controller
This is a very tiny circuit board. You may have to use a magnifier len. I had to!
If you don't remember the wiring. Check the photo you take in the 1st step
Step 7: Glue the Leds to the Side of Each Clip. Just a Little Bit of Glue Is Enough. Try to Have Them to the Front and Back to Be Easy to Understand the Position in the Air.
Step 8: Final Touches
Adjust the flight controller to be on the top.
Guide the wiring through the side of the clips not to be cut during landing.
Attach the battery with duck tape.
Optionally use the bottle tap to cover the upper part.
Step 9: That's It
Test and fly.
The setup is a little bit heavier than the original, more 9g. You will note that during the flight.
Also the grip (the blue circle) is not very rigid and you also notice that is not so balanced.
Behind this 2 issues, it works and you can still fly while waiting for the spares to come☺
