Not rotary related by airplane related:
Does anyone on here know the limits of travel for the V tail Bonanza's
ruddervators? How much was for rudder and how much was for elevator?
Can't seem to find one here local that we can look at (weird...)

I cant speak for a Bonanza, but my glider is a Schreder RS-15 with V tail.
On the glider the answer is it depends on where the elevator is. The
surfaces have a max throw of roughly + - 25 degrees. At neutral elevator all
of that throw goes to rudder. At max elevator, rudder throw is essentially
half. Say for example full up elevator. Both are at the positive stop. Now
kick in full right rudder. The left ruddervator is already full right, the
right one comes back to about neutral. In most phases of flight this is a
non-issue. But the glider is a taildragger and during landing trying to hold
the tail up severely reduces rudder authority.
Note that Sonex on their Waiex went to a Y tail to gain some rudder
authority.
Hope this helps some.
