Too little information to give a definite answer. I avoid buying propellers
(or anything else) but from all I have read it is almost unheard of for
bought propellers too have too much pitch – it is usually the opposite, so
look at other things before trying to change the pitch.
First, make sure that the aeroplane is properly trimmed. This sounds
obvious but it is surprising how often an aeroplane that looks to be moving
quite smoothly through the air is often a long way from the most efficient
trim.
Second, try varying motor cross section and length. This can be a very
lengthy process so look at what other flyers use in similar types of models
to yours and use their experience.
Third, try a different propeller and remember that a bigger diameter will
almost always work better.
If none of that works you probably need a new aeroplane! Seriously, if the
rules don’t stipulate that you must buy a propeller then you can probably
make a better and lighter one yourself from scratch.
