Hi,

They're all good birds. The Yellow is a little more involved as far as the installation of the servos in the tail. This is because there is no visble linkage, and everything (fins/stabs) comes off. Beside that, I think the installation is pretty similar with Eagles with full-house controls. The Y/A Eagle is the most scale, has the best finish and has the gear doors and speed brake (and actuator cylinders) installed. My $.02
