Hello Telly

Just curious……why not use a servo for gun rotatation…….wouldn`t need limit switches then?

Hi Bob

As the post says, it was first idea. Looking at it again, there are a number of things I would do differently if I was to build this type of  model.  At the time I felt that perhaps useing an indirect drive, a servo would not give enough angle of rotation. The drive could not (as far as I could see) be directly under the turret else the elevation pushrod  would be blocked. 

As for limit switches I like to fit something to stop electronics gremlins After watching a multiturn sailwinch servo that had taken in water demast the model by sheeting in continiously, I mod my sailwinch with external limits just in case.

Liked your artical on Becker rudder by the way.

Thanks Tom…………..I was only curious really…….you could have two pulleys and a lacky band.

Those drum winches are naughty at times!

Haven`t seen the fishtail rudder article yet

Cheers…..Bob
