Determined to search for a lighter solution than the last built, the bottle tap quadcopter, I started to play with Lego...again.
So here is the result: a Quadcopter frame with technik Lego, a dream come true, Lego flying ☺
Step 1: Motors and Electronics
To remove it from hubsan, you have unsolder the motors from the flight controller (FC).
Take a photo from the board before starting.
Remember that the quadcopter has 2 clockwise and 2 counterclockwise motors, and that inverting a DC motor, it will spin in the opposite direction.
So the order of the motors is important, and also the polarity of their connections.
Step 2: Mounting the Frame
The middle part frame holds the battery and flight controller. At the same time increases the rigidity of the whole body.
Motor mounts are made of a micro drip irrigation sprinkle.
Respect the length of the motors wires.
Step 3: Gluing the Top Arms
Step 4: Almost Done
Wrap around the flight controller with duck tape right-left direction and use 2 elastics bands on front-back direction to hold the battery. This will keep the frame tight together
Step 5: Conclusions
It is a bit longer than larger, which helps identifying the position while in the air. Due to this fact, also the flight experience is a bit different rolling and pitching. The flight controller handles this very well.
The only drawback are the motor mounts. Every day it passes I feel more motivated to have a 3d printer.
Lego challenges your imagination, and it was funny to remember some good times playing Lego with friends.
Now I'm happy till the spare comes, flying with the toy.
