A propped cantilever carrier is described that can be used in planetary gear systems. The carrier can comprise cantilevered arms extending outward from a central hub. At the end of each cantilever a post can extend downward that is configured to receive bearings and gears. A plate can comprise a hole for each post in the carrier. When the plate is coupled to the carrier it can hold the bearings and gears in place and provide added strength to the carrier. The strength benefits are large compared to the light weight of the carrier (with plate) apparatus.
