Well Grey , we shall see . I don’t think your analogy is a good one at all . Maybe you should look at the other aircraft out there that can lift 8-900 kg and look at the prices . I think the 505 could find itself a very popular lifting machine if it can do say 25% less than the 350 at a price of 50% less . ( and in my experience aircraft can usually do what is in the manual and in the graphs . If mine cannot I will ask for a refund !!! )
