Help! Propeller sizes.....

[kamikaze]

Hi, newbie here just started RC airplane.......

May anyone tell me what is the performance of using different propeller-sizes?

Sometimes heard some flyers said the same motor, but different prop-size will have other effects.......

Please enlighten, thank you.

Firstly i hope i can be of some help,

Different prop does make differernt feel in flying and also chracteristics in flying,

A bigger prop normally slows a plane down whereas a smaller prop will spin faster..
If you are flying Electric or Even Glow, Changing prop sizes anyhow is not that advsable,

For Electrics, see your motors specs and roughly with manufacturers specs you should be able to choose a prop and also normally manufactureres specs should tell you what range of props you can try. Also for Electrics, spinning a too small or too big prop can draw excessive current which your motor and ESC might not take!


Same thing as Glow except there is no Current draw on he Engine, Spinning the Engine outside manufacturers specs can damage the interior of the Engine.

There is also always a way to play with your prop sizes and pitch if you need to mak that adjustments! That I forgot the Equation!

Hope i was not wrong anywhere and hope others could give their 2 cents worth.
cheers.
