There are two memory sections which the Control Center can toggle between. Arms and Jaw The arms swing up and down and the jaw opens and closes using a motor in the front of the torso.
It can rotate on two 84885 independently or together: It is the only biologic form ever produced in Technic, and the motion produced by the three motors is nothing short of magnificent. The cranks techni the blue arms up and down. The weight and lever arm are accurate enough a counterbalance with the addition of internal friction that the helicopter stays up. The lower path drives into a 24 tooth spur and then a pair of 12 tooth bevel gears.
One of the front wheels is used for actual propulsion while a large fan in the rear is used to simulate the propulsion method of a real air boat. Pitch The pitch of the helicopter is motorized and controllable via the side to side motion of the control pad. The final image shows the nose up and down positions superimposed for comparison. The total gear reduction is 3: The movement is quite slow thanks to the total gear reduction of 3: Click for an animation of the arms and jaw in motion.
Note the fact that the helicopter linkage moves a greater vertical distance than the Control Center linkage. There is a battery compartment on the bottom which holds 6 C sized batteries LR14 in series, producing a total of 9 volts DC. tecnic
The Control Center is actually used as a counterweight which acts against the helicopter via a pair of 4-bar linkages. As can be seen in the computer image, the high speed motor drives through a silicone belt blue. The computer image shows fechnic horizontal links in black and the vertical links in red.
Both the head and the tail form a pull-pull loop. In addition to the green pulley cranks, on the same axle are a pair of cams shown in green and lsgo used as cranks.
Bending The dinosaur can bend down and lower its head almost to the Control Center using a motor mounted in the support stand.

The inner linkage is made mostly from gray beams and support the helicopter. The tail is hinged technc three places horizontally, allowing it to forma gentle curve. Roll The roll of the helicopter is motorized and controllable via the up and down leog of the control pad. The use of belts rather than gears allows the pulleys to slip rather than stall the motor when the dinosaur bends fully.
The use of belts rather than gears allows the pulleys to slip rather than stall the motor if the resistance becomes too high.
There is obviously some limit to the amount of memory on the system so it can only record a certain number of inputs, however, I have never found the limit. The yellow link is the key to the whole thing.
The head and tail are linked together so that they move in unison. The Control Center has 3 color coded power outputs, each capable of driving a 9V motor. The total gear reduction is only 3: The output axle shown in green turns a pair of liftarms which use push rods to rotate the dinosaur at its pivot axle on the stand.

Its list of functions is large and so is the modelbut what really makes it stand apart is the way that it can actually be “flown” like a flight simulator. The yellow outputs are labeled “N-S” and “E-W”. The first stage is actually two belts in parallel which drive an 8 tooth pinion gear. The final image shows the roll positions superimposed for comparison. The second pulley drives a worm gearbox hidden. If the A and B buttons are pressed together and then only one is released, the function will stay on until another red button is pressed.
Each control in and of itself is lovely to watch, but the beauty of the Control Center is that all three can be operated concurrently.
The axle at the center of this spur gear shown in yellow is coupled to the gimbal shown in green with a pair of liftarms such that rotation of the axle directly produces rotation of the gimbal. Once a memory is selected, you can push Program and the system will record your inputs, including duration, and including pauses.
Elevation The mechanism for controlling elevation of this helicopted is ingenious. It uses two of the three available motors and about half of the parts.
Finally, a worm gearbox hidden drives and supports the green axle of the gimbal with a pair of rotors such that rotation of the axle directly produces rotation of the gimbal.
