I recommend the Syma X5C.
Integrated 720p HD camera
Slow controls (won't shoot off into the distance the instant you touch the sticks - this makes it easy to fly)
Extreme manoeuvrability. It's an aerobatic drone, so you're sorted there.
I can find one new on Amazon for £30 ($46)
Camera records to SD card, so you can download the footage later.
A word of ...
Not exactly a drone but more or less accomplishes most of the same thing. This thing is pretty awesome:
Update: This product has horrendous support and the software is severely lacking with no plans of improvement for necessary things like LAN discovery.
Found some alternatives (which do not fulfill all requirements) during my search:
Drone Pi (Raspberry Pi + MultWii)
This is quite a big question, there are lots of options with various limitations,
Simple small options could include this Seeed ARM 433Mhz RF link kit these are just transmitter & receivers they would need a separate microcontroller to operate them as well as some form of battery and voltage regulator.
But in depending on what you want you could also use ...
That's a tall order.
I haven't found anything quite that nice in the open source world, although I've looked. Honestly, you might have to content yourself with missing some of those features or going over the 250g mark; if anyone knows otherwise, please prove me wrong so I can look at buying one too! :)
This thread discusses the possibility of porting ...
This $60 kit (FOB Destination) or drone, battery, charger, controller, and miscellany packs up into an included hardcase 8.3" x 5.2" x 2.6", which fits in an overhead luggage bin of even commuter aircraft. The battery is well under commercial airline regulation limits. It provides 1080P video and the drone's video records on iOS or Android smartphones.
If possible, try to not hold the smartphone between your hands. That also blocks some of the signal. Otherwise you could try to mount external antennas to your drone if you could reach the antenna connectors on the PCB. Do know that adding antennas to the drone might result in less stability.
