What do you reckon the maximum takeoff weight is for the Inspire 1?

Note, we know the Inspire 1 weighs 2935 grams (6.47 lbs.) with battery (TB47 - 4500 mAh).

The Inspire uses the new E800 motor. The E800 is rated at 800g lift. So 4 of them gives you 3200g max rated weight. Those are very conservative numbers for this motor. I have seen video with a extra 600g weight added to the Inspire and it still had great flying performance. I don't think there would be any problem going up to 4200g AUW. Might bring your flight time down to around 10 minutes with a load like that.

Excellent, thanks for the information Chris.

Good inform to know, Thanks Chris Merry Christmas

Are you sure about the e800 motor in my limited reacerch over on rc fourms they go into a new dji e800 3 phase even motor with closed loop feed back it was a very impressive  write up by a dji engineer but elsewhere it was speculated  that the Inspire 1 will have 600 motors hence the use of 600 in the air frame  part number.   On a side note I wonder if it would be recommended or possible to do test flying without the camera giblets attached?
