RikHye,
You ever seen the James Bond movie when hes sliding down the banister shooting people as he goes and then he shoots the thing off the end just before he slides over it??

No? You didn't see it?
Well anyway, someone told me once that when he lands he visualizes the plane sliding down a banister. The point being, the plane should always be moving forward and down in a smooth motion. It should have slight nose up so its gradually slowing down the whole time.
When you get good, slight corrections can be made with the thottle and elevator so its touches right in front of you.

Thats how I do it! 1/4 scale Caps and EXtras land like a duck!
