This is a well working drone with long battery life. It is quick and it does not have super sensible controls, so it is not hard to control. This drone comes with four extra propellers in case one breaks. But it is extremely durable so that will most likely not happen. If any other part breaks there is a three year warranty for this drone.

This relates to engineering because machines are mass producing these. It also relates to engineering because it was designed and created by an engineer.
