I would buy the ultra wide convertor for your 16mm and just use it for those really wide shots. The 16mm look better through this convertor. It's crazy. Normally these adaptors are worthless but these things were made to be together.

If you can find it in stock. Read reviews. Great piece for the 16mm pancake. http://www.bhphotovideo.com/c/produc...onversion.html

Hey guys. I'm new to the forum and new to RC but a veteran in aerial video. Happy to finally join.

I have a f550 Naza with the Sony nex-5n TPpacks mount, and a hoverfly gimbal control. Love it, but there's a jitter.

I've tested multiple options and the jitter appears to be the hoverfly settings. Basically when the servos are unplugged it's smooth, but not stable.. (if that makes sense).

I turned down the acceleration settings on the gimbal and it seemed to help but there is still a lot of tweaking to do. I was hoping someone was willing to share their settings to give me a good starting place.

Thanks.

believe it or not i use acclerator settings on tilt and roll that are some where between -10 and 0 crazy I know, but that is where it needs to be for no jitter and fast movement

Thanks Adidas. I actually commented on one of your youtube videos today. wow -10 - 0. Mine is at 300 I think.

Here's a video from earlier today. It looks better on youtube than on my computer, but it gives you an idea.

yeah, i would go down to 0 and see if the jitter goes away.... then work back up

i was around 300 to begin with as well

When I turned the acceleration rate gain down to 0 it seemed like the stabilization hardly did anything, and I still had a little jitter (but less). It jitters a little just sitting on the table.

Anything I can do with scaling factor or etc?

It's raining now so I can't test anymore.
Adidas, are you running the same system as me?

You should start with your acceleration gains at 0. Set the scale factor setting so that the mount compensates with slow motion. Then increase the acceleration gain to speed up your mount a bit.

Most hiccups you see with a stabilized camera mount (small occasional jitters, or loosing stabilization during very fast movement) are a result of limitations imposed by your camera mount and are mechanical in nature. For example, acceleration gain by itself is there for the sole purpose of compensating for the camera mount's inability to keep up with fast movement.

Sometimes you can fix these kinds of things by stiffening your camera mount or using higher voltage to your servos, or using faster servos.

I have an esc bringing down voltage to 12v for my downlink.

Will that be too much to send into the hoverflygimbal?

Well the HF gimbal will take
I think up to like 22 volts.

But whatever you put into it it will also send out to the servos and receiver plugged into it.

Most Rx cannot take 12v and most servos cannot either.

I would pick up a BEC that is either variable (castle creations with the link to adjust it) or a non adjustable that is at 6v

The mks servos you have run on 5 or 6v


Can you hook 12v up to your HFG, yes..... Should you, probably not.
