		<description>Rahim, I&#039;m not sure what you&#039;re referring to.  Slipstream and gyroscopic effect are two different things.</description>

		<description>in a single engined propeller when doing an aileron roll to the right or for that matter roll over the top or Cuban 8, there is often a necessity to give forward pressure, (holding the nose) passed the 90 degree point...what effect would that be? slip stream of gyroscopic effect.</description>

		<description>Then the aircraft was less affected by gyroscopic precession than by the other left turning/yawing forces, which is quite typical.

Remember, a smooth rotation will result in less gyroscopic effect than an abrupt one, because you have a lower effective force being applied to the propeller disc over a longer period of time.  That&#039;s what I meant in the last paragraph when I said &quot;most pilots don’t generate pitch or yaw rates with enough acceleration to really see the effect of gyroscopic precession.&quot;

Try jerking the airplane off the ground with a small but rapid application of elevator some time.  You&#039;ll notice the gyroscopic effect.  Heck, you don&#039;t even have to do it on the ground.  Try it in cruise while running at high engine RPM, just make sure you&#039;re well below Va.</description>
