Decaff is going to think I'm doing this on purpose but I'm not.... promise!
I'm modeling a X-27, and the tail is like this:

As you can see, the tailplane/rudder/whatever(I forget) seems to be in two bits. When you use it tho, do both bits move? OR only top one? Or what??????
Cheers

I would suspect both move, else why add the weight of the extra rudder?

Could it be that the bottom one is an airbrake?
If so, it'd only be the top one moving then, but yeah.

Confirmation that both rudder surfaces move as one.The bottom is a extension of the primary for better high speed handling.It did not split and was not used as an air brake or spoiler.It seems that the original design called for the whole vertical surface be used as a rudder But wind tunnel testing prove that in that configuration at high speed[Mach+]all positive control was lost.I.E. it exited the airplane.

I believe the spoiler is located on either the wing or back below the thrust nozzle. That's my guess from looking at both CL-1200 and F-104 photos.
