RE: How much speed and torque for servo?
I actually have a Hitec 625MG on my 8ight 1.0 throttle servo. it has lasted longer than any other servo ive had. I burnt out my Airtronics 94357 twice, and not yet with my cheapo servo. IMO you only need around 100oz of torqur for throttle. Faster is better for midair adjustments. For steering, 150+ .15- is fine for my application.
