Funtanas (40 and 90 both) are a blast. These are the best small planes I have had in many years, not to mention how affordable they are.
The 40 size is the one on which I really learned to Torque Roll: you have to keep it in the TR (where as a lot of the thick wings -like U-cando or Flip- almost stay in the hover by themselves). Over here, we usually have 10~15 Mph of trade winds, and its great to see the Funtana T Rolling all the way down the runway.
The F 40 also does nice walls and parachutes, but I had to mix Elev to Flaps. All that is learned on the F 40 makes it easy to execute on the larger planes.
