Apparatus, methods, and systems for adjusting a center of mass of a drone may include a balance track and a repositionable weight. The balance track may extend outwardly from a central region of the drone. The balance track may include a plurality of weight-balance fixation positions. The repositionable weight may be configured to be secured at any one of the plurality of weight-balance fixation positions. Various embodiments may include receiving a weight-distribution input relating to balancing the drone. A weight-distribution balance profile may be determined, based on the weight-distribution input, for determining whether a repositionable weight should be repositioned among a plurality of weight-balance fixation positions on a balance track extending outwardly from a central region of the drone. The repositionable weight may be repositioned according to the weight-distribution balance profile.
