Hello Rex,
* * * * * "Redfern Aviation" would have what you need. The Albatros construction was done by Walt Redfern and Bob
Sleep. The aircraft takes a 200 hp Ranger engine.
Another company you may want to try is "Leisure Sports
Replica Aircraft". Again this aircraft takes a Ranger engine
with options to convert the ranger engine to run upright.
Both these firms have had their airframes tested and meet the requirements of the FAA.
You can also contact Frank Ryder of the Guntersville,Alabama
Aerodrome. He would be able to give you more specific details.
I don't have their websites on hand but you can do a websearch to locate them. Good luck on your quest.
