They have had a great reputation with builders of more 'traditional' (slower) a/c for decades. But I don't recall hearing of anyone using a Culver on an RV.
Their prices have always been very reasonable, and I'd be tempted to at least call & have a conversation with them about building a higher speed prop.
When you call you will be talking with Alaina who is very knowledgeable about the props she builds. I fly one of her beautiful props on my low-n-slow biplane and also look forward to hearing what you find out about RV-appropriate props. I suspect the reason for the scant RV feedback is due to very few RVs being built with all-wood props.
