The latest member of our aerial photography fleet arrived yesterday: an DJI S900 hexacopter (6 propellers).

That brings our drone total up to FIVE, as the SJI S900 joins our existing four units: a little DJI Phantom 2 quadcopter, a new DJI Inspire 1 quadcopter, our workhorse DJI S800 hexacopter, and our big Foxtech FPV K130 octocoper, AKA "the Kraken."

Around the Java Post office, it seems that UAVs (unmanned aerial vehicles) are like potato chips or peanuts...we can't stop at just one.

It's likely that the arrival of this S900 will mean that we will give our workhorse S800 drone a well-earned retirement. It's flown a lot of hours and helped us capture a lot of great images.

The box! A little scuffed up from shipping but, oooo...it's like Christmas in March! Or St. Patrick's Day in December! One of the two.

Our resident tech wizard (and aerial camera operator) Trevor begins the assembly process. Hurry up, Trevor! The boss wants to get this 'copter in the air!

I'm sure there's some very technical term to describe what Trevor is doing at the moment.

When in doubt, refer to the online assembly instructions. Always a good fallback position.

And back to the fiddling. I believe that's the correct term. I'm not up on all the engineering lingo.

Something different and innovative about the DJI S900 is that, unlike many other UAVs, it has hinged propellers that can be folded and secured for transport. When you're readying the drone for flight, you just remove the transport clips and the propellers automatically rotate out into flight position when you gun the throttle.

And, just in case there are complete morons using these things somewhere, it's nice to have this warning label on the propeller engines. God bless the legal department. You have to know there's a story behind this warning label.

A story probably involving a guy with eight fingers.

UPDATE: And this is what the DJI S900 hexacopter should look like when it's all put together.
