RE: lama
in my opinion the lama V from colco is the best bar none. its almost bullet proof, its easy to maintain, its very smooth and stable, and it gets no TBE (toilet bowl effect or spining in wide circles) it can also be tuned to fly VERY fast (got mine up to 10mph in 14feet)
worth every penny, i love mine.
the best place to pick it up is helicopter heaven, they will hand tune and test it for you.
