Modify your top rotor, and measure how much real lift you can generate.
First, modify your top rotor using cardboard, tape, and LEGO. Hint: your cardboard rotor blades will need to angle up to deflect the air down. This is called the blade’s “angle of attack” or pitch.
Second, measure the static (non-moving) weight of your craft using a kitchen scale, and write it down. Use metric units – grams. We got about 202 grams. You ideally want a scale that’s not much larger than your craft. This one on Amazon is inexpensive and a good size.
Third, spin your rotors up and measure how much lift or thrust you can generate. As you increase the speed of the rotors, the weight of your craft should go down. The amount of lift will be the static weight of your craft minus the lowest weight you can get.
Experiment with different rotor designs, motor power (knob setting), and gear ratios.
To submit, post a video of your experiment to your favorite video sharing site (i.e. Facebook, Vine, etc.), and email us the link along with your first name, hometown/state, and the amount of lift you were able to generate (in grams)… email submissions to firstname.lastname@example.org.
