kind of a hard thing to answer solely through text if you ask me. That said assuming you have all assists off and using a full HOTAS + Pedals kit:
when you’ve determined where you want to land you basically want to keep the airframe pointed in the direction of travel so you will need to use rudder to keep yourself aligned. About 20 meters from the ground slowly increase collective to arrest your descent and “catch” yourself on a cushion of air (ground effect). To keep yourself centered, it’s typically recommended looking to the horizon, using your peripheral vision and using small adjustments to the cyclic to keep yourself centered. Once you’re stabilized over your LZ, reduce collective slowly until you land. If you find yourself over compensating or jamming your foot on the anti-torque, you may be using too much power in the collective. You can drop collective slightly or reduce throttle power (the twisty power setting)
The big key is using small cyclic adjustments. the 407 and the G2 are very nimble rotorcraft and otherwise incredibly responsive given that they are unstable flying platforms. When the nose is down, it stays down until you the pilot pull back on the cyclic.
Practice practice practice! Don’t get discouraged because learning rotorcraft is a huge change if you’ve strictly flown fixed wing for a long time. At the risk of sounding all zenlike once you start realizing the helicopter is just an extension of your body that can move in 6 dimensions, your awareness will increase and you’ll then be able to set the helicopter down right at the spot you want
