That is one of the reasons so many modelers have a problem with landings, which in reality are a very easy maneuver. Dynamic pressure can be retained by prop. speed (airspeed), until the angle of attack is too much for the applied force. A heavy model needs to come in very low, adequate power to maintain a skimming attitude, ease back on the engine speed which will create a nose high attitude. Too much power-off will simply take away the stab-elevator function of holding the nose up. The same force under the stab-elevator plus the keeping the airflow over the stab-elevator holds that wing into its angle-of-attack to keep the wing loaded and the nose up. Just taking the throttle off will stop all the good stuff and KER-PLUNK!
It is a constant of slight back pressure as the model slows and the nose rises ever so gently. One needs to FLY the airplane until it STOPS. Lazy does as lazy is.
I was perusing one of my great books the other day "Stick and rudder". I was reading about landing, and avoiding "bounce". One very interesting point by the auther was that a taildragger is supposed to be "3 point" landed, because if the landing gear length were properly designed , then it will place the wing at the proper angle of attack to stall properly. Stalling the wing properly is the key to no bounce landings.
The reason why I am elaborating on this, is because poor landings with the popular warbirds at my club have become rampant. I have been trying to explain that they need to learn how to stall their planes, but this is falling on deaf ears. I recommend to take it high, and do stall tests to get a feel for what it will do. Many RC pilots seem to be afraid to fly too slow near the ground. Granted, you can get too slow, but you have to get properly slow to land correctly. This window seems to be narrower with a heavy warbird, but it is still necessary.
