Balancing Your Payload 

1. Preparation 

To start balancing you’ll first need to balance 
your camera on your gimbal just as you 
normally do. It helps if you have your gimbal 
on a mini tripod for this.

 

Now you’ll adjust both of the Bounce 
Damping Knobs anti-clockwise until the 
compression spring becomes almost loose 
(see pic to the right). This is so that the 
damping doesn’t affect the balancing. 
 
     2. Initial Payload Adjustment 
We start by getting to a baseline loading where the support arms are roughly 
horizontal. We adjust the Payload Adjuster knobs roughly equal amounts to get 
the support arms close to that position. This payload setting will be fine tuned 
later. 
 
     3. Support Arm Angle 
When you hold the stabilizer with the rig loaded you’ll notice that the support 
arms either point up towards the centre or down. The most common use is for 
typical walking shots and the angle of the support arms is not as important as the 
setting for the most optimal smoothing as the vertical movement tends to be 
small. As long as your stabilizer doesn’t ‘bottom out’ during your shot then you 
can go as low as you like with the support arms pointing down in the middle. The 
lower you go the more iso-elastic the stabilizer will behave. 
 
     4. Even Out the Payload 
One of the biggest sources of inconsistent smoothing occurs when one support 
arm has the payload set differently to the other. To test this you’ll need to do a 
bounce test but before that we’ll need to work on your form...
