Drone stocks that are a must

I am a big drone fan and i also think they will rise in value in the following period/years. But the ones that i want to start buying are not available . AeroVironment (AVAV) is not available even if it s listed. The second Draganfly Inc (DFLY) is also one that i want to go big in but it s not even listed. I need the opportunity to invest in these 2. Thank you !
