I've never used gyros, haven't even seen one in the 26 years of working with steadicams, so please excuse my total ignorace on the subject. However I'm interested in finding out a bit more about them as I'm just about to buy a new Rig and thinking that perhaps I should include gyros into my kit. If bought they may never be used judging on my past experience of not having enough time to put them in place and start them up plus having the sound deptartment complaining about their hum and the producer wanting to know why they have to spend extra on ADR.
One question I have relates to the pound Inch2 (squared) inertial force created by the gyro.
Eg. The Tiffen site quotes that the inertial control given by expanding the battery - monitor distance to the maximum gives 2,564 pound inch 2 (squared), naturally this figure would vary depending on how many batteries and what type of monitor you use but can a similar figure be quoted about the strength of a single K6 gyro acting on the pan axis?
In a previous post it was said that Larry M's set up replaces the Rig's batteries with his gyros (I hope I understood this correctly), I presume that this configuration maintains the Rigs inherant inertial control created by the distance between the Monitor and Gyro as well as adding the stability that the Gyro generates. Is this correct?
Although whip pans are probably not a consideration when you add Gyros and I expect that Dynamic Balance is not a huge consideration either, however in the previous Larry M set up what happens to Dynamic balance. I expect that while the Gyros are not running dynamic balance can be achieved as usual, however when the Gyros are spinning and creating a new force beyond just the mass of the Gyro itself does this effect the dynamic balance?
Is Dynamic Balance important when using Gyros?
If dynamic balance is altered does this effect even a slow pan?
