winch for rescue boat question

[lonewolf]

I have a pvc/pool noodle recovery boat that Diego Boy so nicly donated to me... Ok now here the question... I am useing the 3rd channel of a fs Gtc3 The 3rd channel does not allow a servo to go to neutral.. However I am using the 3rd channel to raise and lower a catch basket... My problem is how to get the winch to stop rotating when it reaches bottom and top. The winch NEEDS to stop at top and bottom. There is enough torque in this thing to rip itself loose or break stuff .

I could really use some ideas..... on how to control this winch accurately.....Thanks a huge bunch !!!!!!

OK so lets brainstorm
