How is your balance ? Maybe you are extremely nose heavy, that would make it fly like a brick. My US 1.20 balances just behind the most rearward range list in the manual. Initially I had it more foward in the range and it felt very nose heavy.

Also don't try a regular landing approach or to glide in with the crow activated. It causes so much drag it is like throwing out an anchor. It is best for dive landings.
