Well, I just wanted to post some info about my progress with the Mig.

In this picture you can see the elevator servo mounted partially up into the fin. It's mounted to two formers that I made. Two 4-40 rods are connected and will be soldered to a third which attaches to the control arm with a heavy duty ball link. The servo is a 645 MG and I think it should provide sufficient torque for the elevators.

The foam fin former is in there just to test the rod movement, I am going to add a wood plate to the aft portion of it.

For the rudder, I am going to use a pull-pull system as suggested earlier in this post. It should work well.
