balancing on the arm VS. balancing on stand
« on: November 30, 2004, 07:50:00 PM »

":">   I now have all my components on my sled, battery monitor etc. I can balance the darn thing perfectly on the stand. I than transfer the sled to the arm and fly with it and it falls out of balance. As well as balancing it on the arm and then transfering it to the stand and it would be out of balance AGAIN!!!!

Is the space time continueum messing with my head...

It could be several things (loose components, loose gimbal, loose cables, etc.). Does your rig remain in balance if you balance on the stand, remove it, then put it back on the stand? What happens if you balance it on the stand, put it on the arm (leave it unbalanced if that's what happens), then return it to the stand? Does it remain balanced? That little test should help determine the problem.

First things first - what's your drop time?  Always start with the drop time.  2.5 seconds - good.  3 - 3.5 seconds - gimbal is too close to COG and will not hold a balance.  If that is kosher, we can explore other possibilities.

I am having trouble understanding "drop time"

(Izz must B N idiot)

My gimbal is balanced, I can give it the old sideways horizontal balancing test and it holds?!?!?

 I need help... I have no more fingernails to bite or hair to pull out... I'm starting to look like that creepy thing from lord of the rings...

Drop time is the term giving to the time it takes for the sled to go from horizontal to vertical. The standard time is 3 sec. So, if you hold your sled horizontally(while on a balancing stand of course) and let go, it should take 3 sec for it to reach the vertical position. That's the standard time. Time varies according to the shot required but at this time 3 sec is the norm.

So what you're saying Charles is the the sled should be a touch bottom heavy to achive a 3 second drop time.
