If we try 3" pitch props that will make the most difference for least effort and arguments. It will reduce the speed potential of all planes by 25% but not the performance differential between engine makes. We don't have to change the scale fidelity rules or add new classes. It would be a hassel for CDs to enforce an rpm rule on a wide variety of engine types. But just having a specified prop would be easy.

There are very few people I have met in RC combat who are nicer than Dean (Tattoo). I am real sorry I won't see him and Sassy at the NATS in Muncie. He will be missed, but that is what happens when you divide your group into smaller components, you don't see some of the folks ya like.
