On the EC120 the more interesting question is - who designed a 5 place helicopter with a wonderfully big luggage area (t
en out of ten). Then dropped a large boll--k by fogetting to test it ie you cant put full fuel 5 people and luggage in it and get it off the ground, unless your 4 pax are 8 st lithe beauties with g strings as luggage. I now know where I have gone wrong in my flying career !!!!!!!!
