Mike and all, Wren is not in "flux". I just got a new Wren 44i Turbo prop from them. Also had a Gold case, air start, 44 upgraded to a 44i kero start and they are currently repairing another 44i Turbo prop I put into a swamp in Mass. I have had lengthy conversations with Mike regarding the upgrade and the TP repair. Wren is up and running.
