Today something, I had in my inbox for too long...
Milan Reindl (grohl), also member of Kostky.org (Czech LEGO forum), presented us with a model from a SU-47 Berkut (S-32/37 Golden Eagle) [1, 2, 3, 4]. A forward-swept Russian experimental supersonic jet fighter, that was tested in 1997 for the first time.
Looking at Milan's video below, I imagined how difficult it should be to produce a video for a non flying LEGO plane.
Well... even more difficult if it would fly ...
According to Milan the building of the MOC took nearly four months of work.
The plane is,
- 91 cm long, 72 cm wide and 24 cm high with a lowered landing gear.
- 5 PF motors (3 M-motors; 2 XL-motors)
- 2 IR receivers
- 3 linear actuators
- 2 pneumatic pumps and 7 pneumatic cylinders
- 2 sets of PF lights
The landing gear can be lowered and raised by means of three Linear Actuators powered by two PF motors (one M-motor in the front and one XL for the main landing gear). The front wheels turns left/right using one M-motor, while the wheels on the main landing gears help the plane to move forward by means of one XL PF motor.
The model also features a pneumatic compressor powered by M-motor. The compressor supplies seven pneumatic cylinders that control other five functions: one for opening the canopy, one for the movement of canards, two for ailerons, two for elevons and one for rudders.
The model is enlightened by two sets of PF lights on the ends of the wings, left rudder and the top side of the fuselage.
Amazing details and very impressive, isn't it!?
Now, it just needs to ride the skies...
