Housing

Close up view of the lower electronics housing (upside down in low mode). It shows you the two fine balance adjusment (trim knobs). They can be set up to be on left side, right side or both sides.

Why we placed the trim knobs at the bottom.
We could have placed the fine balance adjustments anywhere, after all every bit of this sled was designed from the ground up. So why do something so radical as this? The answer is simple, MAXIMUM CAMERA STABILITY, RIGIDITY and ERGONOMICS

Ergonomics
Your trim adjustments can be on any one or both sides of the sled. What could possibly be more natural than holding the sleds gimbal handle in your hand that you normally hold and operate it with, and with your other hand (the one that you pan and tilt with) reach over and trim your sled, all the while you watch and feel the balance change? There is no swapping of your left and right hand on and off the gimbal handle and on and off the sled post, while you turn a knob then, regrab your sled and gimbal handle and see the effect of your trim adjustment, only to have to do it a second time.

Just think about that for a minute.

I too, at one time, taught myself to trim my sled constantly moving my hands back and forth. I owned many rigs over the years.

Maximum Camera Rigidity/Stability.
When you remove the X-Y plate away from the camera platform, you remove a large percentage of the possibility of the camera platform resonating, which shows up as vibration on the screen. Other factors are center post diameter, material it is constructed from, post wall thickness and post length. A sled does not have to be loaded down with a heavy camera to resonate, nor do you have to be moving fast. There are numerous variables that can cause this to occur. Many of these are common, unknown to the operators setting up their sled.

The Ultimates stage is rock solid, no vibration.
