Introduction
The GRAUPNER E-Trainer 140 is an elegant,
ultra-lightweight
electric-powered trainer
aircraft. At the development stage we placed great emphasis on low take-off weight, and
this is reflected in the model’s excellent performance and flying characteristics. The E-
Trainer 140’s docile handling makes it the ideal model for the first stage in flying “full-
house” aeroplanes after learning to fly on a rudder / elevator type. The model is easily
capable of simple aerobatic manoeuvres, while the large wing area and selected wing
section endow it with very good-natured flying characteristics and neutral handling. The
nosewheel is coupled to the rudder to provide accurate steering when the model is taxi-ing
and taking off.
The model is primarily of balsa construction, strengthened with plywood reinforcements in
particularly highly stressed areas.
The model features a two-part wing, which makes it easy to transport it even in a back-
pack on a bicycle. The tailplane is also removable - it is retained by two plastic screws.
The fuselage, wing panels, tailplane and fin are supplied factory-assembled and covered
