Hello Paul,
You made me weigh my Inspire again, which was good since I didn't remember its weight anymore.
The total weigh of my own is 6 Lbs. ( 2.73Kg) including the 3D printed canopy. It could have been a little lighter but I printed the parts with an infill of 50% to 80% which is a little more than regular prints. Some guys here recommend infill as low as 30% to 40%
Moreover, the electronics, motors, Battery and metal parts are heavier that those installed in smaller drones.
I hope this helps,
Victor
