Step 1: Step 1: Build the Body
After you have the bottom layer done, you will build the top layer directly on that one, this will hold the bottom layer together. This time, starting in the top right corner and working your way counter-clockwise, you will need to place one 4x2 block connecting the 4x2 and 3x2 blocks below it. You will need to place the block so it covers four pegs on each block. Next, you will take a 3x2 block and place it up against the 4x2 in the last step, this will connect it with two pegs on the 3x2 and four pegs on the 4x2 below it. Now you will need to place a 4x2 vertically next to the last 3x2 block. This block will connect with four pegs on each of the 4x2 blocks below it. You will next need to place a 3x2 block horizontally next to the previous 4x2 block. It will connect with two pegs of the 3x2 and four pegs of the 4x2 blocks below it. the final piece to create the body of the helicopter is the 2x2 piece, this will connect next to the 3x2 piece in the bottom right.
Step 2: Step 2: Build the Cockpit
Beginning from the top left and going clockwise, you will need to place a 2x1 block horizontally to you. Next, you will place a 1x1 next to the 2x1 block. Next to the 1x1 block, you will place a 2x2 block, this will put one corner by the 1x1 block and leave two pegs "hanging" off towards you. Now, you will place a 2x2 block next to the previous one. A 1x1 block will need to be placed next to the 2x2 block, at the bottom left peg. Next, place a 2x1 block next to the 1x1 block, now the top half and bottom half will look like mirrored opposites. The 2x1 clear block will be placed lastly in this layer, it will fit snugly between the two 2x1 pieces on their left-most pegs.
For this layer you will need to place a 4x2 block over the 2x1 blocks and the clear 2x1 block. to its right, you will place another 4x2 block, this one will cover each of the 1x1 blocks, and two pegs each of the 2x2 blocks below it. Lastly you will place the 4x1 block next to the previous 4x2 block, it will connect on the final two pegs of each of the 2x2 blocks.
This layer will be simple. You will need to place a 2x2 block on the middle four pegs of the middle 4x2 block. You will next need to place a 2x1 block directly next to the 2x2 block, it will sit on the middle two pegs of the 4x1 block.
You will need to connect the white propeller connector to the propeller, this can be done by inserting it in the hole already in the propeller. The propeller should have the pegs pointing away from the connector after connected. Now you will place the connector on top of the 2x1 and 2x2 blocks, using two pegs each.
Step 3: Step 3: Build the Base
First you will need to lay the two 3x2 blocks next to each other (as shown in the picture). You will also need to place the two 2x2 blocks next to each other and next to one end of the 3x2 blocks. The joystick can be created by stacking the 2 1x1 blocks on top of each other and placing them on the middle connector. The middle connector will now need to be attached between the two 2x2 blocks, using one peg from each of them. You will need to place the connector so that it is next to the 3x2 blocks also, or it will not fit in the cockpit during the assembly step.
Step 4: Step 4: Build the Tail
The tail is a pretty simple design. You will start by placing the 6x2 block in front of you. On top of it, you will place the 4x2 block. This block will connect to the four pegs on the end of the 6x2 block. After the 4x2 block is in place, you will need to attach the middle connector to the end two pegs of the 4x2. The final piece is the 3x1 block, which will attach to the middle connector on one end of the block.
Step 5: Step 5: Build the Legs
Step 6: Step 6: Assemble the Helicopter
Next you will need to attach the tail to the body. There will be a 2x2 slot on the right side of the body that the 6x2 block can sit on. The 6x2 block will need to be placed so it has only four pegs attached to the body.
After the tail is attached to helicopter, you will need to attach the cockpit. The cockpit is probably in two pieces, one with a 4x2 block, two 2x1 blocks, and one clear 2x1 block. This piece will need to be placed so the clear 2x1 block is sitting between the middle two pegs of the body. The rest of the cockpit can be placed right behind this piece, the two pieces will touch each other, but not overlap.
The last part to attach is the legs. The legs can be placed on the bottom of the helicopter. They will need to be attached to the base. One of the white uprights from each leg will need to be placed on the outer corners of the 2x2 blocks from the base. The other upright from each leg will need to be placed in parallel with the first one. The upright will likely connect to the second from the end hole of the 3x2 base block.
Congratulations, you have now completed your own Lego helicopter.
