Elevator Actuation for B-47 Model

[Capt. Midnight/pdf3@comca]

Hi Scratch Builders!

I'm building a 1/16th-scale B-47.  I want to actuate all control surfaces internally (no surface actuation).  The horiz. stab. and elevators have about a 35-degree sweep.  Has anyone come up with a good way to rotate the elevators?  (The Hobby Lobby plastic cam actuators could be used, but tend to be somewhat flexible; Rotary Drive actuators could also be used, but there is very little room for the servos in the horiz. stab.)  Any suggestions would be appreciated.

After being as boggled as Greg about the scale, I got to thinking about my R/C flying days, way back when.

How about sandwiching a piano wire rod along the elevator hinge line and running it into the lower fin structure with a 90 deg downward bend when it gets there. Then you could hook up a push-rod to the lower end when it reaches into the tail of the fuselage and use a conventional servo further forward.

I used to have a thing for T-tailed R/C gliders and made similar hook-upsto get them to work but using an all-flying tail, and they worked pretty well, but of course the down-ink in the fin was quite a bit longer than yours will be.
