Rafa,

thanks for your feedback. That sounds about right - setting the control moment about 1/2" out from the rudder; in my case, on each side. A 4-40 bolt 1-1/4" in length should do nicely and should provide adequate precision as well as torque.

Maiden is hopefully a couple of weeks away - will depend on the hours I find to finish her up as well as the arrival of some electric juice!

David.
