Hey,

I just got my Pilot and have been working on getting it balanced. (I have been using a Glidecam for a while and im able to get that perfect) I believe i have the camera balanced pretty well (although i havnt achieved dynamic balance yet) but when i shoot some test footage i can "feel" vibrations in the footage as im walking. what is this cause by? is the arm not set correctly? any help would be amazing:)

Thanks.
Yoni.

Hi Yoni.

The vibrations on this sled are famous... someone say that happen when the post is fully extended. Anyway, those can be the reasons of your problem: zoom lens, mattebox, rods or camera don't fixed, slack between vest and arm, slack between gimbal and armpost, wrong tension of the springs, slack between monitor and monitor arm, slack of the extra weights and finally, slack of the batteries! More the masses are moved away from the centerpost, more there is a danger to increasing this type of problem. Hope not had forget anything.

Best, Steve.

Thanks so much for the response:)
So i dont have the post extended even halfway, no zoom lens, no matte box. I have rod and follow focus system, but that seems to work perfectly on the glidecam. but what do you mean by "slack"

Thanks again!
Y.

Like loose.... The problem could be the quake/shake of your legs if you have no training.

Thanks steve! i guess something must be loose, as i have been using the glidecam with the arm and vest for a while now so im used to walking smoothly. I also got dynamic balance this morning...finally, bso i guess something must be loose somewhere (hopefully thats the problem)


Thanks so much!

i have heard of this vibration but have never experienced it myself on my Pilot. like stefano said go down the check list. get in the habit of setting up with a specific routine. you also could be "flying light" what camera are you using?

Oh I have those sometimes, I tend to duct tape evrything from cables to V mount battery but still...sometimes it happens. LIke a sweet spot. Oh it is a 3.800,00 USD rig and it is 2 years on the field, airplanes, cars, trucks, boats (mostly DSLR work on a wide 'n glide gigs).... damn I am happy that even works !
(I am looking to Zephyr, am I an idiot ?)
