Gyroscope mounting and balancing on the ARRI Trinity: post position, counterweight strategy, and power feed configuration.

What the thread found

  • One operator mounts a Kenyon KS4 gyroscope horizontally on the rear battery plate with an AB-Mount, running the rig fully balanced without the gyro first, then enabling it at approximately 15% authority to avoid over-damping the boom.
  • Battery configuration places two large batteries forward in a triangular pattern, with an optional third slim battery opposite the gyro; this slim battery powers the gyro independently to avoid draining the camera battery.
  • Counterweights positioned opposite the slim battery and gyro create a coplanar feel during operation.
  • An alternative approach mounts a single Kenyon KS2 on a post clamp near the post base, with three batteries distributed at the base.
  • ARRI accessory plates are available for mounting transmitters, batteries, and gyroscopes; operators have requested longer ARRI rods to expand weight distribution options.

Depends on

  • Configuration depends on camera weight, lens package, and desired boom sensitivity.
  • Gyro authority setting interacts with operator technique and shot requirements.
  • Available mounting real estate on battery plates and post constrains placement choices.
