It's more stable when the gimbal closer to the lens. In order to keep a 2-3 second drop time, more weight on the bottom will force you to move the gimbal away from the lens, which decreases stability in the tilt and roll axis.
For the Pilot, I've found it best to have 2 lbs on the bottom and 8 pounds on the top. This keeps the gimbal around 2 inches from the stage and provides enough weight at the ends of the bottom crossbar to provide good pan inertia.
The XH-A1 is 4.5 lbs. The BP-950G camera battery is 1/2 lb. I'm guessing the Rover Snap Quick Release System is around 1/2 lb. That's 5.5 lbs. Add 8 middle weights (4 on each side) and 2 end weights (1 on each side) to the stage and you've got 2.25 pounds of screw-on weights up top. This all totals 7.75 lb of top weight, which is near ideal.
On the bottom, 4 middle weights (2 on each side) and 2 end weights (1 on each side) add up to 1.25 lb. With the AA batteries, that totals 2 lbs.
Hope this helps,
Dave
Hi Dave,
That setup worked great.It really help with the stability...thanks again for all of your help.Mt steadicam training DVD should be here Monday!....let the games begin!
