More?

A neckband to hold the remote.
A hardshell case. To carry all the junk to the church lot.
A landing pad - it aids in RTH.
Prop guards. So I don't have to buy as many props. ($5 for 2 props)
Legs. So landings are easier.
Helical 5.8 ghz antenna. Because I gotta try anything different.

I worked in the antenna world for 20 years so when I discovered drones...aka quadcopters I also found there was an aftermarket for antennas - especially if you race your quad.
The helical just touches a sweet spot where no one else can scratch my itch.
It may not help in the least but for a total of $14 I can give it a shot.

Droning On

$25 to Hubsan and I got 8 props - 4 gold and 4 black (2 As and 2 Bs of each).

Okay, maybe they make add on legs? Yeah? And guard for the props?

Now the issue is that it won't fit in the ABS molded case with the legs and guards attached and I am not about to carry a screwdriver and fit parts for every flight.
To come up with a quick connect system.

These first world issues are killer.
