Such thing as GYRO effect?

RE: Such thing as GYRO effect?
The term is gyroscopic precession.
http://en.wikipedia.org/wiki/Precession
All motorcycles experience precession, which is the reason that you must counter steer in a corner. It is also the reason that at low speeds, it seems more difficult to turn right than left. A gyroscope will tend to "walk" in a counter clockwise direction, or the same direction of a left turn. And YES, I did a research paper on this for Physics class.

RE: Such thing as GYRO effect?
Carbon fiber does not flex once you make a rigid shape. I owned Signature Marine in the 80's. We made Ocean Racers. We were experimenting with the C/F material but did not vacuum bag nor put it in a autoclave for curing. We did not have pre-preg (resin saturated C/F material) as it was not invented at the time. We made the outer skin out of 3/4 oz mat than 3 layers of unidirectional glass 0-180 degrees, 90-270 degrees & 45-135 degrees (not stitched together with mat in between, not invented yet). We put a sheet foam (sandwiched) striping (Divinicell, or Klegicell) than put one layer of carbon fiber on (inside of the boat or last on the mold)
The decks (31') were transported by 2 men, one in front & one in the back. The hulls were the same way (different lay-up). Impact is not a friend of Carbon Fiber because it is so rigid. Our theory at the time was; the glass will flex when impacted by a 100 mph wave into and absorbed by the foam. The (inside the boat) C/F rigid skin held the boat hull straight. This boat in 1980 did very well as it was much-much lighter than the other boats of the day. In ocean racing, back then, they made them heavy to go through the waves.
They are using them in small model airplanes for the military (military channel last night) where they put cameras in them & fly them over the battle for observation. I am sure it will not be too long they will be carrying hand grenades.
As far as your question, there is no or very little wheel flex. It fractures as an example of a crush test designed to crush the wheel. The wheel deforms until it is torn apart by force. My 16" wheels are somewhere around 1,300 lbs. This is a press with a round solid shaft on the ram. I hope this helps and has answered your question.

RE: Such thing as GYRO effect?
after reading all of this.... I'm not sure what the OP meant by the wheels turning into each other? does the rear try to come to the front and the front try to lag behind???????
btw: LONEWATIE - good explantion on gyroscopic precession - boy - I remember those days.
