Bob,
i have a set of W10 plans which state stalling speed with flaps 43kts and stall speed without flaps 49kts @ gross of 646kg (1425lb)
I was looking over a Tailwind this morning which is a regular visitor from Montpelier,beautiful aircraft i love them a bit heavy for RAA though.
Its little sister the Wittman Buttercup would be a perfect fit for RAA http://luceair.com/replica_buttercup.html
