RE: precision eagle inline engines
Hi Mustang,
Precision Eagles were made by Don and Carla Kanak of Planes Plus. Carla was actually the machinist who made the engines. The last I knew they were into turbine models. You might check with the jet jockeys to find a current website/point of contact.
Another person to see about inline engines would be Ralph Cunningham (Antique) here in RCuniverse. He may be able to fix you up with a engine.
Good Luck
