Sail winch

I have a scratch built 45" Motor sailer and will be using two [color=#FF0040]120G EXI Servo w/ Continuous Rotation B1226 sail winches, one for the sail sheet and the other for raising and lowering the main sail (gaff rigged). The sail sheet will need about 12 " travel, which the winch will handle with 3 rev's. The main sail winch will need about 30" , but my understanding is that these winches only have 3 rev's (12" of line). Can these winches be altered to provide more rotations or should I go with a motor and reducer with no rotation limit? Any info will be useful. Thanks -- Karl1

Hi Karl
Yes they can, at least the Hitech sail winches I use can (for the life of me I can't remember the model number BBXXXX something or rather).
Problem is the feedback pot value has to be changed. I have never done it personally, but a techy type person at Hobby One in Brisbane did it for me at a reasonable cost.
So in answer to your question..... yes!
Cheers
Paul

a much cheaper solution would be to replace the poti in any ordinary servo with resistors for infinite rotation
