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. There is a battery compartment on the bottom which holds 6 C sized batteries LR14 in series, producing a total of tdchnic volts DC.
Rotors Like virtually all Technic helicopters, the main and tail rotors rotate. The first stage is actually two belts in parallel which drive an 8 tooth pinion gear. The upper jaw pivots on the purple axle when the entire head is lifted by the yellow cable around the pink axle. The organic movements would be much more difficult to replicate with gear systems.
The weight and lever arm are accurate enough a counterbalance with the addition of internal friction that the helicopter stays up. Oddly, the lower jaw does not really move but rather is fixed at a 90 degree and to the neck which does move.
Image by Benjamin Wendl Click for an animation of the helicopter rolling. The inner linkage is made mostly from gray beams and support the helicopter.
The total gear reduction is 3: The cranks oscillate the blue arms up and down. In this case, they are motorized to turn at the same rate via a motor located in the body at the approximate position a turbine would be located in a real helicopter. This is a reasonable assumption since a creature with such a massive head would need to use the tail for counter balance. This can be further appreciated in the animation. 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.
This is due to the fact that the yellow coupling attaches to the inner linkage one stud further from the rotation axis than it does to the outer linkage.
The computer image shows the horizontal links in black and the vertical links in red. Because of the significant steering angle and the fact that the steering is located in the rear, the model can turn on a very tight radius.
It uses two of the three available motors and about half of the parts. Note that batteries must be installed in the Control Center even if you are not using them to get the balance right.
This dinosaur is supported by and integral with a gray stand which contains the Control Center. The mechanism to control the elevation is rather complex and is pictured at right. The helicopter is mounted to the stand with a box structure called a gimbal. Click for an animation of the dinosaur tipping. They are controlled by a 4 way control pad on 845 right.
As can be seen in the computer image, the high speed motor drives through a silicone belt blue. The large A and B buttons on the Control Center command the rotor motion clockwise or tecjnic.
This marvelous helicopter is nearly the best ever produced in the Technic line with the possible techhic of Fan and Drive System. Depression of the Control Center raises the helicopter. Click for an animation of the rotors in motion.
A worm gearbox in the body allows roll port and starboard about 20 degrees. Model technix Benjamin Wendl Click for an animation of the dinosaur in motion. The yellow outputs are labeled “N-S” and “E-W”.

Elevation change is the only non-motorized function of the model. The Control Center has 3 color coded power outputs, each capable of driving a 9V motor. Items of the same color remain parallel throughout motion which keeps the helicopter mount perpendicular to the ground.
Arms and Jaw The arms swing up and down and the jaw opens and closes using a motor in the front of the torso. The final axle drives the wheel. Steering The hidden rear wheel can be steering using a second motor in the body. A set of bevel gears drives both the main and tail rotors. It is tethered to the Control Center via wires which are not really long enough to allow you to stand up and follow the model along while it drives along the floor. This particular unit is nearly identical to that found in except that the buttons are a different color and it has an input for a transformer!
When the Control Center is lifted, the helicopter descends into a gentle landing on the attached landing pad. It can rotate on two axes independently or together: This dinosaur presumably a Tyrannosaur is one of my favorite models ever. Movement of the forward cables tips the head side to side, and movement of the rear cables swings the tail side to side.
The lower set of pictures shows the complex geometry of the legs which mimics the estimated musculature of a real creature. Click for an animation of the arms and jaw in motion. The gray buttons in the center control programming.
Note in the photographs that a number of wires have to be carefully routed through this area without interfering with the motion of the parts.
