Reason for lack of Servo love is it was always a second rate Crave until the Crave started being produced in-house and got less stable. Now that the Crave has been US, the Servo has finally started getting a bit more popular. I'll still not throw it. The rim doesn't have any good color options.
I have a Patent Pending Servo that I love but I haven't tried any of the newer run Servos because I'm afraid they won't fly anything like it.
