Drones have been the talk of the market for a few months, but most investors still don't know how to buy into this huge opportunity. Aviation giants like Boeing (BA -1.64%) and Lockheed Martin (LMT 0.63%) are so large that even a significant share of military and commercial drones would barely dent their financial statements. 

But there's one small company that's already a big player in drones. AeroVironment (AVAV -2.67%) is the maker of some of the military's smallest drones, often launched by hand -- even drones that can fit in the palm of your hand. 

Fool contributor Travis Hoium has been watching this company evolve for years, and now that commercial drones are on the horizon he thinks it's time to buy into this opportunity. Find out more in the video below.
