Greggk, There's the Sequence and the Extreme Flight Vanquish ll (I have the orginal Vanquish, which is a excellent flying plane and the M ll is even better) and there's also the Helios 25e and the Aspera in the 46 to 50 inch range of planes, I don't think you would go wrong with any of the five listed so far. I have three of the five and I'm looking seriously at the SebArt planes also. It's hard for me to pick a favorite of the ones I do have.
