ONE-WAY BEARING IN PAN GEAR
Since the VR360 Carbon is the camera mount AND the landing gear for the helicopter an
issue exists upon spooling up the rotor blades of the helicopter prior to take-off. e
torque generated during spoolup can cause overdrive the pan servo and cause the
helicopter to spin until sufficient tail rotor authority is gained. Over time this
will damage the pan servo.
Since spherical 360 panorama shooting requires the camera mount the
camera only pan in one direction the VR360 Carbon incorporates a one-
way bearing in the pan gear hub. e one-way bearing locks the
helicopter to the camera mount in the direction of rotor blade torque
but allows the servo to spin the mount freely in the opposite direction
for shooting the panorama. is feature allows for the use of inexpensive
low torque pan servos and eliminates the risk of damaging the pan servo.
For oblique and video shooting the one-way bearing can be disengaged and
our optional “Pan-Lock” installed which locks the helicopter to the VR360 for
spoolup , yet allows the camera mount to pan in either direction after take-off.
PAN-LOCK (OPTIONAL)
As an upgrade to the standard on-way bearing in the pan gear hub,
PhotoShip One offers the Pan-Lock.
Unlike the one-way bearing, the Pan-Lock allows the
camera mount to spin in either direction once in
flight, but locks the mount to the helicopter on
the ground.
A spring loaded star shaped cam seats
into position when the weight of
the helicopter is on the camera
mount. As soon as the helicopter
gets light on the skids and takes off the spring loaded Pan-Lock releases and allows for normal panning in both left
and right directions.
Once the helicopter touches back down the Pan-Lock latches back into position and locks the mount to the
helicopter ready for the next spoolup.
e Pan-Lock is a direct bolt on upgrade fully compatible with our helicopter mounting adapter kits as well as our
Astro mount kit.
