Many modelers do not know how to properly configure there aircraft for landing. when setting up to land just dont cut the throttle to idle and float it in. That works with some sport aircraft but you will start to have issues as you move up to other aircraft. You probaly still have the mindset that power makes it go fast and elevator makes it go higher. Power controls altitude and elevator controls airspeed. Your aircraft is trimmed for flying around but not for landing. You need to configure the airplane to land. Back off on the throttle on the downwind leg let some airspeed bleed off and start to feed in elevator. When you get the aircraft slowed to where you want it add power to maintain altitude. Start your turn to final approach and use the throttle to control your decent. I like to cross the end of the runway about 4 feet off the ground. Once I get a couple of feet off the ground I power back and start my flare. I expect the aircraft to touch down about 1/4 the way down and roll out about half the length of the runway. Get up in the air and pratice slowing the airplane at altitude. Adjust the attiude and use the power to hold altitude. I like to do this with a trainer. On the ground I trim the elevator to about 8 degrees up elevator and leave it. then I manage power to fly and maintain altitude. Once comfortable with this you can fly using only power and rudder. also, read redfox435cam post on this thread he says the same.
