Understanding aerodynamics made the difference in my landings 12 years ago. I've since obtained my full scale license and models and full scales use the same aerodynamics. This is what we do with full scales.

Use throttle to control the rate of descent. Engine power makes the plane go up - not elevator. That's critical. If your descending too fast add power and if your too high reduce power. When I started using power, my landings began to work for me.

Use elevator to control airspeed. That's critical. Up (back) elevator slows you down and down (forward) elevator increases airspeed. You may be trying to slow the rate of descent with elevator and slowing your plane to a stall. If that happens you need to nose the plane down to maintain airspeed and if you're too low add power. At all times keep air flowing over your wings.

Use the suggestions in the other replies to get lined up right, they're good suggestions. Model Airplane News April 1992 has a nice article by Bob Gilbert that reviews some of this stuff. If you want to contact me I'll email you copies of the articles I have.
