How about "trim "the airplane for a slower speed, just like you would do with a real one.  Most adjust the elevator once for high speed and never touch it again.  When this is the case, and you pull your power, the airplane will still want to seek the speed it was last trimmed for - probably too fast for landing.  Proficient rc pilots can fly the landing pattern with some back pressure, but many new pilots can't.  Re-trim the elevator, or program a landing switch if you have that capability on your radio.   When speed changes, trim changes.  </p>
