    [MOC] Sky Crane Copter

    Thanks for all your comments ! It takes about one month, not all day, so I will say 50-60 hours...

    [MOC] Sky Crane Copter

    Hi, Thanks for your comment ! For the functions,it is the more convenient I found : never stop the blades !! :)
  3. Hello everybody, If something is not clear, please ask, english is not my language Here is my last moc: a Sky Crane Helicopter: General: Length: 80 Width: 29 Height: 27 Rotor diameter: about 75 Container: Length 30, width: 11, height 12 Number of parts: 894 all inclusive (manual or with PFS) Design: At first glance, we recognize a type of helicopter Sky Crane: leggy, long and thin, prominent turbines and especially a huge rotor: On the body of the vehicle, the choice of two-tone flatters the eye, an orange border highlights the line and even gives a sporty look to the model! For the cabin, the orange panels allow good highlight the rounded nose of the aircraft, made with white liftarms mounted on flex: At the rear of the panels of the cab give the rectilinear shape of the cabin. The cab roof takes up the two-tone orange piping and large white panels, it's almost like a sports car hood! Turbines, well highlighted, black is easily detached from the rest of the vehicle. The use of wheels, gears of different diameters can refine the turbine. The mechanisms at the front of the copter, also in black, are used to give relief. Cab, massive contrast with the rest of the long, thin copter. Similarly, the landing gear looks very frail. We find the orange border on the legs of the landing gear. The tail assembly is thin and slender. The rear rotor drive shaft visible outside the tail is another characteristic feature of the Sky Crane present on the model. The tail rotor blades 4 and above the horizontal drift gives volume. Finally, the main rotor is given strong presence to the vehicle. The diameter of standard blades (like about 65: 31 + 2 * fixation) is not enough for the model. The diameter has been increased, it now reaches 75 like! Suffice to say that the helicopter must! In addition, the use of various connectors can give yellow color and simulate mechanisms on the rotor. Such a rotor is problematic to expose the model along a wall for example, but by removing only 4 liftarms 5L thin can be easily removed easily wins 2 blades 25 cm deep, without harming the general appearance of the model. The container matches the rest of the helicopter, white and orange: In manual mode, the handle is visible on the left front of the unit. Right side of the cab, a door allows access to the control of the battery case. The PFS elements are also fully integrated in the cabin. Mechanisms: The model is very simple mechanically. There are two main mechanisms: rotor rotation and winch. It may be added, as a secondary mechanism: suspension, directional front wheel and the container locking system. For two main mechanisms, there is a BV with two selectors. The first selector, left, used to operate the winch in one direction or the other. (bottom of photo) The second selector, right, has one function: activate or not the rotation of the rotors. (top in photo) If it is in manual mode, the crank drives a 12T SB makes a bevel with a 12T DB to raise an axis through the cabin. If you are in PFS mode, the motor is mounted vertically, so there is no the first bevel gear. The rest is the same. A second bevel gear 12T SB / 12T DB can direct the axis backwards. It is this axis which carries the first selector. Pushing forward the selector switches in the driving ring of the red wild 16T which in turn causes the 16T of the output shaft. By pushing forward, it triggers a mad 16T will operate a 20T DB, offset in height. The rotational axis will cause a second 20T DB will rotate the DB 12T of the output shaft. There are thus two ways to drive the output shaft or with a gear linkage, or with both. So for a given direction of rotation to the input, rotation is reversed by pushing the lever forward, the rotation is not reversed by pushing the lever backward. This is option is especially useful when the model uses the PFS. From the output shaft, is driven a couple VSF / 8T. Finally, it is on the axis of the 8T what fixed the cable drum. The cable is routed into the body of the helicopter to leave behind the main rotor. This position is determined by the size of the container and the position of the fixing to bring the right container in the middle. This prevents the container tilts when it airlifted. On the input shaft of the first BV, there is a cascade of gears: 16T / 16T / 16T Mad. If you push back the second selector, driving ring just mate with the 16T Folle. The movement is then transmitted to the axis. We walk directly to the main rotor. It shifts the movement towards the center and upwards with 3 16T (16T / 16T Folle to center / 16T to mount). With a bevel gear 12T SB / DB 20T, the rotation axis is vertical and it drives the main rotor. For the rear rotor, starting afresh from 20T, we have a bevel gear 20T DB / 12T SB and heads to the back. Two gimbals to track the shape of the tail of the helicopter. Arriving at the end of the tail, a trio of gears to switch the curvature (SB 12T / 20T SB crazy / 12T) and a corner last reference (SB 12T / 12T DB) can guide in the right direction the axis of rotation of the tail rotor. The suspensions have the function of absorbing (more or less) the soil unevenness. The directional front wheel lets you play with the model on the ground and rotate smoothly. Fixing the container is very simple. At the front, blocking is provided by 3L pins with axes attached below the helicopter. On the container, the "Axle and Pin Connector Perpendicular Split" connectors come dragging in the pins. At the rear, a small spring mechanism ensures proper maintenance of the load. A controller drives a shaft and a 8T / 8T couple to get off a post. On the lower axis, brackets (3 * 3L) rotate. When the lever is released, the spring mechanism reduces the brackets to the front and upwards. In this movement, the brackets crochet the container through a conveniently placed axis. The well attached container, one can make any kind of maneuvers the helicopter. To release the container, simply manipulate the joystick again and picks one container. A small diagram LDD: Green: movement entry Red: winch with double meaning BV In blue: the BV rotors with all the main rotor and tail rotor tracking Orange: the system for attaching the container Manual To PFS: This helicopter can also integrate the PFS. Here, everything happens in the cabin. It begins by removing the crank and its axis. Then detaching the cabin of the helicopter body. To do this, simply detach the body of the roof (two pins), remove the white liftarms bent, remove the panels on the back and liftarms L orange on top. Finally, one can draw the cab forward. The liftarms is removed by L (3 * 5L) and lifarm 7L which bind to the rear of the cab. Can then be inserted in the battery case, the engine takes place next. Finally, we can put it all together.
