What is you mission for your aircraft? Whatever it may be, a 200 can probably fill it. My wife and I race ours (we’re the current Spot Air Race Leauge champions for production aircraft), I use it for cross country business travel, we’ve camped out with her at MAOA Member Steve Freeman’s air museum and last weekend took our daughter and son in law to a short grass strip out in the swamp with a cajun restaurant on it. Just had to delete fuel to add PAX.
Ed was right about contacting Siracusa. He does have the maintenance manual and the flight manual in electronic form for the D model. Contact him or instant message me and I can forward it to you.
Good luck with the hunt and don’t hesitate to ask this group questions.
