I would stay away from a Pitts or a Christian Eagle until you have some biplane experience! As Bob states above the GP Stearman is a good first bipe and the Ultimates are excellent. My first bipe was a CG Ulty and I had a lot of great flights with it. World Models has an Ulty in every size. The Aeroworks birds are good but are built on the lite side. Does not take much to doink them. The CG is pretty beefy. Good Luck in your decision!
