A fully developed stall without rudder pedals would likely be unrecoverable, especially if it was power-on. Here I have to disagree.
I do power on stalls in my 415c (No Rudder Pedals) all the time, the nose
is pointed up at this angle ( / ) and when it breaks it just drops the nose, the
ailerons never lose control.
Another thing I love doing in the coupe is catching thermals. In a 45
degree climbing turn, zero air speed climbing at 800 to a 1000 feet per minute.
It won't do that with full power.
On page 12 of the "Aircoupe Owner's Manual
Ercoupe"
STALLS
The unusual stall stability characteristics has been designed
and built ito all Ercoupes by the use of a limited upward elevator travel and in
addition the exact manner in which the wing approaches the stall condition. With
the low wing monoplane the stall or breaking of the airflow is most likely to
start at the junction of the wing with the fuselage if no fillet is used. With
the Ercoupe specially designed fillet the airflow starts burbling at the rear of
the fillet when the speed of the aircraft is reduced to a point a few miles per
hour above the minimum speed, and the stalled portion gradually spreads out over
the wing as the speed is reduced. The outer tip portion does not stall even when
the unusual amount of maximum upward elevator is used, and so the stability and
aileron control are satisfactory. The burble flow over the central portion of
the wing serves another useful purpose in that a warning is given to the pilot
that an approach to a stalling condition exists. As the speed is reduced to
about 5 MPH above the minimum a mild form of buffeting occurs which increases
somewhat as the speed is reduced further. This buffeting automatically warns the
pilot that he has a little reserve speed left for such purpose as to recover
from the stalling condition. The recovery from all stalls in the Ercoupe are the
same as used in recovering from stalls in the conventional
aircraft.
The limited elevator control not only insures stability and
controlled flight conditions throughout the low speed flying range, but it
prevents spinning as well. The aircraft is designed in such a manner that it
will not balance or trim in a spin. It has been tested under the most unusual
and extreme conditions and has never shown any signs of spinning. Therefore the
aircraft licensed by the Federal Aviation Agency is officially rated
"CHARACTERISTICALLY INCAPABLE OF SPINNING".
