skywalker x8 motor mount

Since the original motor mount of my skywalker x8 broke, i decided to design this one.
It fits perfectly inside the original motor mount and allows me to change the motor since it is not glued in.
It has two parts , one for the outside an one for the inside......both parts make a sandwich with te fuselage.
Just need to drill 2 holes to fix them together.
works great.
