Hi, this is my k'nex gyro system operated car. The whole car is made entirely out of k'nex. It uses about k'nex 250 k'nex parts and 4 k'nex racing wheels. I made the original car from a design that I saw in a car magazine and I used the design it's shape to create my car. The gyro system is made out of two prototype steering mechanisms that didn't work as steering but they were turned around to create the gyro system. A perfect weight balance as well as good orientation make the system operate better without the use of any elastic bands or R.C truck suspension. The whole car has been into many separate parts and each of them has been studied to make them work better and able to be lighter than the previous model. A sturdy and strong under-car chassis which has been upgraded and lightened makes the car more durable when it is being used. When the car's gyro system is not being used, it can adapt to it's normal wheel camber making it move like a normal car. The gyro car will perform better than any of my previous k'nex models on all-terrain surfaces or flat area's due to its' ability to use the gyro system in these situations. The whole car is very light and small but it performs much better than any other car . The car is 29.5cm long and 20cm wide but height is extremely low totaling 7.5cm which makes it the lowest k'nex car with a mechanism on the wheels. The whole time for the modifications was approximately 5 hours and roughly 150 k'nex pieces were added to the car. Parts added: an Pagani Zonda style exhaust for effect. A meaner looking front end for a hot ride look. An engine or parts which are visible on the car. A roof on the middle. More added features will be highlighted on the pictures above. Thank you for viewing this instructable and happy building!
