The EU-1 is fine, but for an earlier classic designed as a large plane, you might want to look into the King Altair from Jeff Petroski at Homeandhobbysolutions. I have flown my "Kings" on an OS.91 and a Saito 125. Both engines worked, but were not overpowered. A 140 would not be tioo much engine.

In a few months Jeff will introduce Ed Kazmirski's large-scale gem the SIMLA. This plane was designed in 1965 and has a 102" wingspan. It was featured in the August 2010 Model Aviation article KAZ!! The prototype model is nearing completion, and will be featured in an upcoming issue of Model Aviation in a construction article
