Default Elevator vs. all moving stab?

Hi wsmalley,

I have seen various jets fly with all all moving stabs. One that springs to mind is a scale F15 which flew here in Australia at Shepparton one year. The fuse was around 6 ft long with a 10 - 12 thrust turbine. The only aerodynamic control surfaces it had was the horizontal stab (elevon/ailevon/rolleron) for pitch and roll. It flew perfectly.

I have also flown full scale gliders with all moving horizontal stabs. They allow for a far greater trim range, increased responsiveness but a greater tendency for the unitiated to induce Pilot Induced Oscillations (PIO). This would only be magnified in a scale model, but then again, see comments about the F15.
