Landing
As mentioned above, there is no substitute for experience, but here are a couple of points you might like to consider:-
1/ Lining up properly with the landing strip in lateral position greatly simplifies landing, as it gives you a lot less things to think about. Try a few low passes (not too low!!) along the centerline of the strip as if you were trying to land on a strip about 20 feet higher than the actual surface.
2/ Speed is the key. Too fast and it's almost impossible to stop bounces, too slow and you might suffer from a few of the dreaded effects like dropping a wing due to tip stall etc. Fly with purpose down to a height where you are happy to start the last phase of landing. By that I mean, a slightly steeper downwards angle on the approach, especially for a trainer and in wind, will give to a lot of confidence and stop you having to correct for ballooning until right before actual touch-down. Be prepared to give a few clicks of throttle to reach the start of the runway.
3/ Some trainers have the tendency to try to take off again after they seem to have landed. Many a good landing has been spoiled by the fact that a trainer has a wing that is low loading and 'wants' to fly! This is sometimes caused by the undercarriage giving the plane an upwards angle (too much incidence) , when it settles down on the landing gear, giving the wing enough incidence to try to lift off again. Make sure the model is more-or-less horizontal if you have a tricycle gear, and, in the case of a tail dragger, the tail wheel doesn't set the tail of the plane too low.
4/ I found that a simulator is a great way to get 'finger memory' to keep the plane horizontal when it passes you for the landing. The old suggestion to move the stick towards the dropped wing when the plane is coming towards you works, but you need to make the adjustments without having to think about it and that only comes with experience.
Any guitarist will tell you that he relies on his fingers 'knowing' where to go on the fretboard to form a chord, and it's much the same for flying.
In other words, if you land enough times, it's almost a dead certainty that you will suddenly 'click' and find that you start to wonder what all the fuss is about! The human mind goes through a strange learning process!
Whatever you do, and however difficult you think it might be at the moment, remember the best pilots in the world had exactly the same problems as you do now!
Hope that helped!
