Day 1:

We start brainstorming what type of helicopter we should be making. We decide to make a CH-47 Chinook, and I begin to prepare materials.

Day 2:

Gavin finished the design, I found some motors, and Alex found propellers. We just started making our product. Also, 3D printing is completed. We begin to assemble our propellers and attach them to the motor.

Day 3:

We finished making the motor part, and the laser cutting of the skeleton of CH-47 is finished. Gavin and Alex assembled the first motor onto the skeleton. I did some soldering of the motor and picked some good-quality 9-volt batteries.

Day 4:

We assembled the second motor-propeller system to the skeleton. After a few tests, we don’t think the helicopter will lift up, but there is no time left for us to change that day.

Day 5 Last Day:

We tried our best to make two new propellers. But the helicopter is still struggling on lifting up. We can’t find a better motor in such a short time.

 

Improve:

I think we can choose a more potent motor. The major problem for our helicopter is that the weight is too much for our motors to function. If we can solve that, I think there is a chance that it can fly.
