Default Control surface design question

My question is has anyone ever made a plane taking the concept
all the way and made a "wingeron"?

It's probably not practical for a real plane but I thought it might be
an interesting experiment to try on an RC plane.


I have a radio control 'pitcheron' slope glider and bits of several more.
There are two schools of thought: 1) use differential wing pivoting to get
roll control and use a separate elevator on the tail ('wingeron') and 2) use
differential pivot for roll and summetric for pitch with a fixed tail
('pitcheron'). Typically both types roll like crazy. Pitcherons have a
reputation for being a bit sluggish in pitch. Find an R/C site and search
for names like 'Orca', 'Ultron', 'Shrike', 'Pica', or just pitcheron and
wingeron. I have a Pica and most of an Orca.

By the way, the F/A-18 (all models) has separate rudders/verticals.
All-moving rudders have been used as far back as the A-5 ('Vigilante'),
which had NO 'conventional' (for the time) control surfaces. Stabilator for
pitch, all-moving rudder for yaw, and spoilers for roll. The Volksplane
has/had an all-moving vertical, if you want something similar.
