Lego Technic 42040 Fire Plane

Lego Technic 42040 MOD

The Lego Technic 42040 is a very nice seaplane and fire plane which can drop bricks of water. Several functions are available for this set : ailerons and rear wings moves with a joystick, v2 motor is connected to three-blade propeller (which is a little bit large) and hidden wheels. Transparent-blue bricks can be stored in the plane, dropped trough a small grey button, and re-filled by opening a hatch on the roof.

Nevertheless, I really dislike the main wings : they’re profiled like a commercial plane, which is not realistic at all. Moreover, main wings are not correctly positioned on the airplane : they’re too distant from supposed gravity center, they should be positioned more forward. This can be seen in the pictures below.

Lego Technic 42040 Wings

My modifications on the Lego Technic 42040 airplane are focused on the main wing. It has been moved to the front of the cabin. Command for ailerons have been moved also, and a new hatch to fill the transparent blue bricks has been designed. I tried to keep spirit of the designer, with colors, solidity and building process. With these modifications, style is more realistic, but maybe less attractive for youngest Lego Technic fans.
