Hi

Yes smaller prop with the same pitch will rev faster.

Which is ok as long as you don't go to far and exceed the rev range for the engine. The revs will increase a bit in flight to what you can measure on the ground.

Props that are even better than master airscrew ones for not breaking easily are Kavan

As a moderator perhaps you should alter the name of the thread to reflect how it mutates instead of threatening to close it.
