Hi everyone, This is my next project. Its a replica of the brand new Agusta-Westland - AW196 Air ambulance. This model is a lightweight transport helicopter designed to be able to achieve missions in about every possible environment. This is also one LEGO project, and I have tried to take lessons from my previous helicopter MOCs. At this point I have achieved the most difficult part of the MOC. The complete control center of the rotor's head is done and perfectly functional. But before, have a look at the global model in it's WIP state: The global shape is coming out of the bricks actually :) On this picture you can see one joystick standing lateraly in behind the pilot seats: And you have the same on the other side of the aircraft. Other point of view: So, what's the goal? I already build previously helicopters with onboard command, even realistic commands. It was pleasant but not always really practical. So this time I decided to make use of a pair of joysticks, one on every lateral side. The left joystick controls the cyclic movement of the rotor. When pushing it to the front/back the swashplate incline to the front and back (forwards and backwards translation of the aircraft). Pushing the joystick up and down makes the swashplate incline left or right (lateral movement of the aircraft) The right joystick controls: the collective mouvement of the rotor when pushing it up and down The pitch of the tail rotor (command is operational, tail rotor still to build) Actually, the main rotor is perfectly functional with large amplitude movement of the blade. This amplitude was a real goal of this MOC, because I found lots of beautiful build on the net, but not really one with real large movements of the blades. Other view of the rotor head, i'll explain you all of this later ;) On the other function point of view, the BB already is placed in front of the rotor in order to assure a good wheight repartition on the 3 points landing gear. I will place now a gear box with to reversible commands on it : one for the landing gear in/out command and one other for the winch, that actually does not exist. There will also be one main clutch gearbox for the rotors, in order to be able to use of the other function without rotor rotation. So, that's it for now guys, this is the first take of it. Building time: about 20 hours actually. Any comment or idea will be appreciate. -
