Just by changing props will increase the RPMs from 9,000 to 13,000??!!...wow!...please let us know if that is the case. Now, once you achieve that, what happens with the plane...it will fly faster I suppose, will it climb faster as well?...will it consume more fuel?...what about vibrations? and engine wear?...can the EVO take that much speed?...today I noticed that at full speed this thing vibrates like a paint shaker...man does it vibrate??!!!
Why would you want to increase RPMs to that extent?
Thanks in advance for the lesson.
The stock prop is meant to have a highly oblique pitch while presenting a large blunt disk to the airflow.
It is purposely designed to make the plane very "docile" for the novice.
Switching to a two blade prop as he is contemplating transforms the plane, increasing RPM and effective power transfer, making the plane much quicker and more responsive.
It's worth doing this once you are through basic training.
