Hi, I have been flying a phantom for a while now. I have decided to upgrade to an inspire fire given the recent price drop. I like to film sailboats over water, The most action comes when the wind is up strong. My in-laws fly an inspire commercially and informed me that it would be a better machine for those situations. I think the X3 camera suits my needs just fine, so I was not too concerned about buying an older inspire and not having the upgradability to the X5 camera. Last night I came across some differences in the T 600 model compared to the T601. Particularly given the range. Most of my flights in the Phantom were operated at the limits of the video fees range. So I've been trying to make sure that I purchased a T601 model. Problem is is that I do not any advertisements specifically listing a T601. So my question is, is the T601 otherwise known as the version 2.0? Or is the T601 any new inspire manufactured after December? I see BH photo with an v1 at $1,500 and the v2.0 at $2000, however the range is listed the same?
