Is there a common method or equation for determining what length servo arm to use for a particular surface? I know this has a lot to do with the throws required for the type flying that you will do but whats the next step? I need to buy some arms and not sure where to start as far as the correct length for the best mechanical advantage at the particular throws involved. I also know that the power of the servo is in question if the length of the arm is long enough to provide excess leverage on the servo shaft. Does this question make any sence? I am really looking for a more general application answer rather than spacific lengths. Something that could be used on all applications.

Thanks,
Bob
