I remember backwhen one or the oother ofthe 805 or the 815 used to be a 3.5 turn winch and the other was a 90 degree servo. Now for sure the HS-785HB is a low buck 3.5 turn winch. The others seems to both be 90 degree servos. Weird. Of course I could be wrong about the current 805 and815 bought from some places.
