Ringleitwerk Graupner 4462.114 For ERGO 30/50. This annular tail set in the style of
the BELL 400 provides an improved, less turbulent
airflow through the tail rotor, plus enhanced protection
in the case of ground contact. Used in conjun-ction
with the smaller horizontal stabiliser this tail
makes it easier to fly “3-D” aerobatics.
