Hi guys..............One thing to look at is the balance of the plane. It´s difficult, very difficult to hover if the balance is not right. Your plane should be tail heavy when compared to a sport plane...how much??? trial and error till you get what is right for you. Remember that a tail heavy plane is harder to control at slow speed and harder to land....[:@]....but not that bad
Try using expo on all your surfaces....I personally used a lot on the sim and with the real world....it help a lot.
