Hi
I had been looking at the Spitfire build on this site and noticed the pictures of the servo drive to the aileron (a RDS system is used) I had not seen this before ,so whilst waiting for glue to dry, I turned up the parts and made a working system.
My question is, taken that torque is force x distance how with the drive coming from the centre of the servo ( giving zero distance in the equation ) do I work out servo torque ?
Thanks for your time
Happy Christmas

Arthur,start by assuming that the servo torque is applied as a point load at the furthest point from the axis of rotation where the outside edge of the 'box' in the aileron touches the drive rod.

Rob, does the torque not increase in value the closer the axis of rotation?

Cary, I think the torque is constant but the force increases as the distance decreases, and of course visa versa.

Barrie, I knew it was something like that! Thanks for the info!
