Default arm vs drum

I am not taking sides in this debate since I have successfully (?) used both arm and drum winches.

At the recent IOM world championships two of the top finishers used arm winches. It appears they used Hitec 5735 digital servos with a custom carbon fiber arm with a pekebe block at the end. The servo was modified using the HFP-10 servo programmer to change the standard swing from 90 degrees to what looks like 120 to 140 degrees. The lines were configured in a double purchase arrangement to get the necessary travel

Yes arm servo's tend to use a lot of current, especially in high winds, but they are faster than drum winches.
