Hi, just upgrades from my glidecam to a Pilot and the thing is great.

However I am having a little trouble with my balance and Im not sure what it is. I thought I was pretty good at balance.

I have everything in static balance, the cameras CG is marked and in the right place. All is well.

But I turn the rig 90 degrees and then the camera is no longer balanced, it tilts to the left. rotate another 90 degrees and now the lens is pointing up or down. Rotate again and its still off. Back to the start and its all in balance.

Any ideas what can cause this? Why would it go off balance from a simple 90 degree rotation? The gimble appears fine, looks smooth and rotates on the same axis. Dynamic balance is actually ok as it rotates, but when it stops its when its all off.

Thanks

This is becoming quite the epidemic.

Thanks Brian, I take it the only answer is to contact tiffen and arrange them to look at it. Do they tweak or do they tend to replace the entire gimble?

they tweak it, it's a matter of moving shims from one side of the gimbal to the other. Seems that it takes generally less than half an hour.

Thanks all, have contacted Tiffen Europe yesterday to see if there is anything they can do and am awaiting a response.

Not sure if the UK office does repairs or is just an office. Hoping we can get this sorted soon as I have yet to even fly the thing :)

Yeah, you'd have to talk to Tiffen about doing the fix yourself, but looks like you're already on that track. Good luck!

Met up with James Elias from Tiffen UK today who instantly knew my gimble was out of balance, must have been the way I was walking :lol:

Left it with him for an hour or so and when I cam back it was all done. Nothing as severe as shimming, just some special screws on the side needed setting.

Got home, all setup and now have perfect balance and perfect dynamic balance.

It was like Aladdin's cave. There just moving in but there were merlins and ultras all over the place. And even those damn expensive merlin weights just knocking about :P

I experienced the same problem lately. No chance to reach DB. So is it possible to fix it by myself? I met James at a workshop but i live in luxembourg, so no chance to visit him.

Cheers
