Parts List for the custom-drone can be found here. It also contains the prices for each component used, along with the vendor link. Also, we purchased some supplementary parts which can be found in the purchase sheet linked here.
For the Fall 2019 semester we moved to DJI Matrice M210V2 drone and we purchased a Manifold 2C as an onboard computer. To build the fire extinguisher for the new drone we've used the same parts as mentioned in the above link.
