As a pretty big RC enthusiast, I splurged and bought a quadcopter this year (Phantom 1) with 2-axis gimbal (pitch and roll). As an amazingly fun toy hobby (I SAID HOBBY*, FAA), these drones are absolutely amazing. I can't believe the explosion in ability and innovation lately. As a storm chase tool, there are a lot of cons with a few pros. Watching a lot of the viral drone videos, I'm getting more and more worried about how ballsy people are getting. Just goading the FAA to crack down...
That said, I did have mine on all our chases this year and deployed several times. Most storm chase days are 99% unflyable due to winds (I don't fly over 15 MPH). We did get a couple lucky days right at the interface of the RFD and inflow where you can get a few minutes of calm air. If anyone's gonna get good drone tornado footage, I bet it'll be there.
My personal flying rules are to
1) Make sure the column of air around you is definitely
Class G airspace (just one more hectic thing to check).
2) Don't fly over or around other chasers. NEVER accidently photobomb their timelapse or video.
3) Don't fly in higher than 15MPH winds, otherwise even with the 2D gimbal, you'll get enough yaw to make shots unusable.
And Shane is soooo right about raw drone footage. Painfully boring to sort through, edit down, and stabilize. It added so much time to my workflow this year.
