I like your solution for the rudder control on the B-24.
I built the 110 (about 5 years ago) using the stock horizontal stabilizer which is as you know a solid slab of wood. Using a dremel tool I carved two smoothly curved channels for the Golden rods to sit into. The servos for both rudder and elevator are located behind the wing. It is not the greatest setup and does have some play, but to this point has not exhibited any signs of flutter and does allow for adequate ground control on takeoffs. I also used mechanical retracts, I believe the company that makes them is called EZ(or something like that). They have been very durable despite some heavy landings.
Hope this helps![IMG]
