The biggest hate I used to have was slowing and landing helicopters. Sometimes they would start yawing left and right and go out of control.
Helicopters are not as easy as planes and take a lot of practice. One person suggested several hundred practice landings before you start to get the hang of it!! I find slowing down in plenty of time is best. It's hard to replicate a true life landing where you could race in and bring it to a stop and hover in a matter of seconds.
I find very small quick sharp inputs are best, as a helicopter will always take longer to respond than a plane, but seems to remember what you asked it to do and will keep pitching if you put too much input into the joystick.
Stick with it, as the rewards are definitley more challenging than planes, especially when taking off and landing on oil rigs!!
