RE: transition from ff to hover
Do you have any fixed wing experience? If you do than think of the helicopter as just another airplane. The rotor disk is just a wing. You still have all the the basic control; elevator, rudder and airlerons. Your throttle controls the speed of the turning rotor blades. Increase speed and you increase lift and the opposite to decrease lift. Your landing approach is similar to that of an airplane. You will control decent using the throttle and elevator. The transition from forward flight to back into hover is a matter of timing and airspeed. Allow the copter to decend to about twenty feet and flying parallel to yourself with a separation of about thirty feet. Use the elevator to bleed of airspeed until the copter almost stops than apply forward stick or down elevator and at the same time increase the throttle collective. Sounds simple but believe me it is not. I'm still consider myself a beginner. In this part of the RC community you never stop learning.
