IMO a D will out lift an E. They are lighter, and I personally dont like the panel on the the E, takes up too much room/visibility and I think the instruments are positioned better on the D.
Dont know what an F will lift, though have heard that the transmission becomes the limiting factor.
at sea level a D will lift 1000+ pounds with wind on its nose and cool temps. I have picked a 1300 pound drill piece , with the thing stripped, and MINIMAL fuel. You are not going far with that kind of weight.
For less than 3000> msl and cool temps , you cant beat the angry egg. For anything above that, the need to move loads far, or hot temps go As350B2/SA315.
