Post by suvroI really don't know much about r/c helicopters
Not to discourage you... flying RC helis is something you can learn but
it certainly isn't easy and it certainly isn't cheap. Flying a RC
helicopter takes a LOT of practice. Many experts suggest you purchase a
simulator first before moving on to an actual model.

Post by suvroI need to build or buy a helicopter that can lift about 2 lbs of
weight
Thats a good payload for most helis... however a 60 size can do it. But
now your talking a couple bucks, not to mention the repair costs of
crashing it, (avg $600.00-$1000.00 per crash), the community noise
level restrictions on model flying, muffler requirements, flying on
other than private property, and liability insurance in case you lose
control of it, hit a bystander and open their skull.... just to name a
few.
Make sure you only consider gas or electric. Stay away from nitros due
to the smoke they emit. (not good when its clouding your photos. If
you're aware of all these issues.. then the Observer is one that comes
to mind:

Actually with the advent of Lithium- Polymer batteries electrics are
easily up to the challenge and can handle 2 lbs no problem. Electrics
offer no smoke and less vibration. (vibration more critical when
shooting video).
An interesting electic heli (sort of) just announced a couple weeks ago
is the new Draganflyer 5. Whats unique about this DF5 (over earlier DF
models) is this one "flies itself". It has on both on-board gyros and
positional infrared sensors. If you get into trouble and start loosing
the ship, simply let go of the control sticks... and it rights
itself... even hovers itself! Problem is... it won't lift two pounds.
(not even close) On the other hand, it does come with an on board video
camera that will transmit to a receiver. You capture the image on a
laptop computer and then you can makes still from the video frames you
need. (Providing you aren't shooting for National Geographic or need
36x48 enlargements. Anyway... check out the videos:

Another option is the RC hot-air balloon. You can lift 20+ pounds:

Need a nice mount for your ballon or Heli:
