I would not know if its the right prop, your plane will tell you that. All the models respond a little differently to different props.

I can say this you are right in the perfect RPM range where I like to run my motors.
If the plane likes the prop then run it. Prop choice is always an experimentation thing....Conditions change sometimes you need speed, and sometimes you want a geared down setup that will help the pilot control the pace.

Its not always a case of "I can pull the throttle back if I have too much power" This is true but in reality the prop choice does a bunch for how the model responds and draws lines. Just flying at half throttle is not enough. The pace of the model is a huge factor in how well the pilot flies.
