yeah, its a big sucker, I am about 5 foot 6 inches tall so that gives you a good idea of the actual size., each blade is 700mm long. thy now have a few 800 size helicopters that are capable of flying 3D but crash cost on something like that is extreme, I would hate to see what a crash on my big one would cost.
here is a video of my big one flying if you are interested in watching it. I am not super good, better than allot of people in the hobby but I suck compared to the guys that compete in the big competitions. I am not sure that this is one of my better flights but I don't have that many videos of the big one. I have only been out flying a few times this year, kind of taking a break from RC I guess.
