Gunradd, do you know the difference between the EVF 5612 and their EVF 2 & 3? Is the 2 &3 just newer fan designs?
The advertised weight of the EVF 2 that Shaun is installing is 2lbs 3oz with ESC installed. I don't think Shaun has weighed it to double check advertised weight vs actual. I would think that the weight should be fairly close to a Stumax 110 fan that is 1.5lbs w/o ESC. I am also planning on running 2 Revolectrix 5s 5000mAh 60c batteries as long as they fit.
I'm hoping it's going to be in the 15lbs range.
