RE: Head speed & pitching up
Balance the heli using the flybar. Lift the heli by flybar using a finger on each side, it will be pitchy if slightly tail heavy or even dead on CG. Increase your expo on cyclic helps too. Presumably you are using stock black paddles? can also try V paddles or K&S if you are FFF, not too many 3D pilots do a lot of FFF in circuits etc... mainly for F3C/FAI config.
