Thanks for the feedback and kind words about my new design, guys. It looks like flaperons and elevators will be the way to go. The time and effort to put two servos in the wings and hinge the flaperons will be offset by the simplicity of having elevators instead of a flying tail and struggling to fit it all into such a tight space. Good to know that flaps on F16's are OK, although I get the feeling that too much flap movement is going to cause problems both with wake onto the tailplane as well as making the roll authority a bit mushy. BTW, this one's for 90-100mm EDF but it would be possible to fit a Wren44 size turbine. I'm also doing a larger winged version, swept wings with a tailplane mounted up the fin similar to a Hunter for 100-110mm EDF, this version would suit a 12lb turbine. Thanks again, guys.
