- - Some talk awhile back on using tiny gyroscopes in HPR. I know a guy
- in Austin that uses a Futaba (sp?) gyro in his Sun Seeker to handle
- role stabilization. Gyro is connected to custom electronics package and
- servos which manipulate canard like surfaces. He said that these gyros
- are standard equipment on RC helicopters and are used to compensate for
- the precession effect of the main roter. You will need to have a pretty
- complete electronics lab (e.g. oscilloscope) to build one of these.
- However, it can be done!

- - Jack, the more I think about the orientation of the video tape in
- Randy's rocket the more it makes sense to me to have the tape vertical.
- The transport mechanism pulls the tape out of the cassette and threads
- it though the various pinch rollers etc. If the tape was oriented other
- than vertical then the G forces would tend to pull the tape out of the
- cassette since it already has a designed degree of freedom in this
- direction. Aligned in the vertical direction the tape will be held in
- place by the various tape guides that are used to align the tape across
- the tape heads. A non-vertical orientation would cause the tape to
- stretch or bunch up while is was coming out or going into the cassette.
