Here is another thing too, If the engine idle is to high it will not slow the pane down enough to let it drop with a good glide path. Check your engine idle on he ground if the plane moves on the ground at idle it is to high.

Another thing to do is practice touch and goes. Especially if you are the only one flying at the moment. That is an excellent way to watch your plane for glide tendencies. If you do not like the approach power up and go around and do it again. The problem with many pilots they do not practice landing approaches and touch and goes enough. That is why they have trouble landing an airplane. Recently I was at the field flying my 116 inch wingspan Davis D1w and all I did was touch and goes and landings with it for a full tank of fuel.

Practice Practice practice. That is what makes you good at landings. try to get in closer so you can see the airplane clearly. too far away your judgement may not be as good resulting in a bad landing. If you botch the approach do not try to force it down. Power up and go around and setup up again. That way you can take a couple of deep breaths and calm down again. It works. Good Luck
