If the plane changes heading (roll) during inside & outside loops, you will need to mount the servo on the side.
I usually try to mount the elevator servo (especially with Y-pushrod) on the side using JR Aileron servo tray.

Thanks for the link on this. I may just go ahead and get one of these to see if I can make it work for this application.
