8.2 Fixed Ballast at rear fuselage end
In special cases empty weight C.G. position may be shifted rearward to
allow heavy pilots to fly with rearward in-flight C.G. positions.
Therefore it is possible to install a battery, see section 9.9 (when a battery
box is fitted), a heavy tail wheel hub or a trim weight (drawing 4R8-109)
at the vertical tail fin web lower end using a holder (according to drawing
4R8-107b), see sketch (Tail wheel box and lower rudder bearing not
drawn).
The rear trim weight holder must be
fitted to 4 mounting bolts of the
elevator drive system, accessible
after rudder disassembly. The holder
can carry one trim weight.

Warning: Never dismount the rear trim weight holder, bolts and nuts are

movement of rudder and measure rudder deflections after work!
After permanent installation of fixed ballast, execute a new empty mass
and balance weighing, see section 2.
