What kind of servo and brand are you guys using for the throttle on your engines? The DS821 that came with my Spektrum radio died today while in a flat spin. The engine was at high idle at the time and the plane was down wind of the runway, so I was fortunate not to lose my Wildhare Edge. I put a Futaba S3004 servo on it but with the way it is set up, the idle position isn't very repeatable, particularly if you bring the engine down to idle quickly. There is about a 500rpm difference, ie 1300rpm vs 1800rpm. BTW, the DS821 did the same thing.
