The yellow outputs are labeled “N-S” and “E-W”. Image by Benjamin Wendl.
As can be seen in the computer image, the high speed motor drives through 2 different silicone belts red tchnic white. As can be seen in the computer image, the high speed motor drives through a silicone belt blue.
The use of belts rather than gears allows the pulleys to slip rather than stall the motor when the helicopter hits the stops.
The landing pad is static and remains at the same level. Items of the same color remain parallel throughout motion which keeps the Control Center parallel to the ground. A comparison of the images at the two extreme positions shows the change in muscle and tendon geometry. A pinion gear on the motor drives a 24 tooth crown which then drives the belt system. I wouldn’t want to roll much further than this in a helicopter.
It can rotate on two axes independently or together: One buttons drives one direction, and the other reverses polarity and drives the motor the other way. A flex axle connects here shown in yellow and attaches to the movable upper jaw. The third model, and airboat, is not nearly as techhnic as the other two but is still an excellent model.

A set of bevel gears then drives torque into a set of 8 and 24 hechnic spur gears on the right side of the body. The use of a drive wheel on only one side effectively acts as a differential allowing the front wheels to turn at different speeds.
The cranks oscillate the blue arms up and down. The lower set of pictures shows the complex geometry of the legs which mimics the estimated musculature of a real creature.
When the Control Center is lifted, the helicopter descends into a levo landing on the attached landing pad. The final image shows the nose up and down positions superimposed for comparison.
Steering The hidden rear wheel can be steering using a second motor in the fechnic. Movement of the control pad in a diagonal direction effectively controls 2 channels at once. This model uses the Flex System more significantly than any other model, and probably to the best effect.
It is not immediately obvious from simply playing with the Control Center, but the manual tells you how to technoc the rotors on so the buttons don’t have to be held. The helicopter is mounted to the stand with a box structure called a gimbal. You can then play it back Go at any time, or you can control the system manually.

The gearbox both drives and supports a 24 tooth spur gear. The computer image shows the horizontal links in gray and the vertical links in green. Tschnic by Benjamin Wendl. A set of bevel gears then drives torque into a third belt white which drives a new worm gearbox hidden.

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. The motor which drives this motion is housed in the vertical portion of the stand which raises and lowers with the entire model.
Click for an animation of the head and tail in motion. The arms and jaw are linked together so that they move in unison. The output pulleys shown in yellow are used as cranks. In addition to the green pulley cranks, on the same axle are a pair of cams shown in green and also used as cranks. As can be seen in the computer image, the high speed motor drives through 2 different silicone belts red and blue. This dinosaur presumably a Tyrannosaur is one of my favorite models ever. Elevation The mechanism for controlling elevation of this helicopted is ingenious.
The use of belts rather than gears allows the pulleys to slip rather than stall the motor when the dinosaur bends fully.
