Hi Ripley,
Sorry for the "tardy" response, if you would like a faster reply either pm me or send me an email to:
neil@spooner60.orangehome.co.uk but it is always nice for others who may have an interest to see what is in the conversation.
I have a 56 x 34 prop' on my 1834cc engine which works very well as a compromise between straight and level and aero's, a finer prop' would be nice for aero's, but I can keep altitude if I am really "on the ball" with it, and it works ok for straight and level. As far as changing prop's go, that is a headache with the LAA, so have a look at:

Engine.pdfWho you use to supply the prop' is a problem now in the Uk, Chris Lodge has hung up his "spoke shave", so I don't know who to suggest to supply. I have just bought a prop' from Ed Sterba, I brought it back from the USA, which saved a lot of carriage.
Why do you want to change the prop?
Neil
