ASSEMBLING THE MODEL

5. V-tail

The v-tail is ready prepared with holes for screws to be
fixed on the fuselage.

As the electric version is equipped with an engine, there is
only little space in the fuselage cone. Therefore it makes
sense to install the

servos in the tail

. By this means you

can also

save weight

, as you need no or only little lead.
