Glue flat thin carbon piece as shown in
picture. This will reinforce top of fuselage and
in case of inverted landing will help to protect
depron from bending.
Cut holles for V shape carbon reinforcement.
This is necessary step to ensure both sides of
elevator deflect ecactly the same. Otherwise
elevator controll will be not precise.
Glue bottom part of fuselage inverted on the
flat table. Put some heawy objects on tail and
wings, this will help to keep them straight. It is
very important for precise flying plane.
Now lets reinforce bootom fuselage structure
by adding 1mm carbon rods. Be sure to take a
piece of sanding paper and prepare surface
of each tip of carbon rod. This way glues will
stick better. For easy setup i recommend use
some square helfull tools like CD cover ore
credit/phone card. Take two exact same sice
objects that have 90 degree angle, place
these objects (my favorite credit cards ) from
both sides. This way depron stay straight.
On last picture, you can see all construction
reinforced and already assembled in one
piece. Such reinforcement way is about 50%
lighter than old fashion depron box, that also
had some twist during rolls.
