The upper and lower wings are connected by a dark bluish grey 4 x 1 x 3 tail on either side; this tail element is unique to the set in this colour, although has previously appeared in a couple of sets back in 2003 in old dark grey. The upper wing is also supported by a couple of 1 x 2 x 2 black windows placed back to back in front of the cockpit, which from the perspective of the pilot really can’t be good for visibility. The biplane has a three blade propeller and the tips of the blades are stickered prior to sliding the propeller on to a 6L axle protruding from the front of the fuselage where it’s held in place by an orange 2 x 2 brick with domed top. The last step is to attach a 1 x 4 x 2 bar to the top of the upper wing for the Wing Walker to hold on to and then we’re done with the biplane.
The programmable Lego brick which is at the heart of these robotics sets has undergone several updates and redesigns, with the latest being called the 'EV3' brick, being sold under the name of Lego Mindstorms EV3. The set includes sensors that detect touch, light, sound and ultrasonic waves, with several others being sold separately, including an RFID reader.
