I made a v-tail for an old unknown graupner or multiplex glider. 3 part design with two reinforcing carbon spars in the fin and one in the rudder. feel free to scale it and mix it to fit whatever plane you have.
rudder breaks away kind of like supports after Printing. slots for hinges are included.
Fin requires some special settings to work.
Z seam alignment set to user specified and setup so it does NOT start the lines at the leading edge of the fin or trailing edge of the rudder!
GRID infill at 10 to 18%
connect infill lines
infill overlap 15%
fill gaps between walls disabled
filter out tiny gaps enabled
8 line brim
Center connector piece can be printed with 2 walls.
Try setting the infill so the two rear reinforcement spar holes gets connected to the infill. the most forward hole does not need this as its tilted and always get connected.
