Signal Fish Tutorial: Motors and propellers

Version 5

    We have three motors on our rig. One motor is responsible for lifting up the balloon. The other two motor sections are across from each other, and enable the balloon to move left, right, forwards, or backwards. Each motor bracket is exactly the same and is adjustable on our rig, making it easy for transportation. If the bracket is too far pulled out, it would disrupt the balance and make it a bit wobbly, making it unstable for flight. Here’s how it looks by itself, detached from the base of the rig:

    We experimented with different size propellers after finally settling on a size. Here is the 3D printed propeller located on each motor:

    The proposed propeller used on each motor. We decided instead to buy them separately.
