    Default Best Greabox Ratio for Model III with 582

    I recently aqcuired a HFIII with 582 and 3.0 C Box.

    I need to replace this box (due to corrosion issues). Question is: Is the 3.0 the best ratio to be using?

    I have heard some concerns in our EAA Chapter that having a integer number for a gear ratio is not a great thing as the gears can develope wear patterns (constantly mating in the same way) and also some harmonic feedback issues.

    Any thoughts here? I have the 3 blade wood GSC prop, new in the box, but have not yet mounted anything so would also be open to prop changes.
