An example fully trimmable tailplane in a general aviation airplane is the Mooney, at least the 201 and related models. Look at pictures of it and compare it to, say, a Cessna 310’s plane. You will see the “trim tabs” at the back of the 310’s elevator and none on the Mooney 201. I seem to recall some tail draggers I flew had no trim tabs too.
