The plane in the right hands is capable of FAI. However as you get into the upper classes, there is an advantage to the larger ships. That being said, it is not required. Jason Shulman won an FAI contest last month with a .50 Era model that his company sells. The workload would be a lot higher, so that is the biggest advantage with the 2M stuff. In the right hands though, this is an FAI capable design with the correct setup.
