Not only is it possible, it's very easy. I built my Mini/Flyer sled with ground notched markings for each pivot point, delineating where the elements needed to be locked in order to be in dynamic balance for my camera. Works well.

Here ya go.

1. Open the battery plate to about 45 degrees, lock a bit but leave some room to move it. Mount a battery. If it's a heavier camera, mount a 2nd battery on the 2nd plate on the battery plate.

2. Fold out the monitor arm until it's flat horizontal.

3 Place the camera onto the plate, screw it down, mount it into the top stage.

4. By using the normal method of back and forth and side to side, find static balance on the sled.

5. Give the sled a spin. If the lens tilts upwards, the sled is precessing to the back. Take the battery plate ( the part of the Mini and Flyer that has both battery snap-on plates screwed into it ) and very slightly push it down, moving it slowly towards the vertical. If you were very close, then we are talking a few mm of pivot and no more.

6. See if this solves the problem. If not, push it a bit lower. If your camera and sled are in static balance but the camera tilts DOWN as you spin it, take the monitor arm and slowly pull it upwards away from flat horizonal. Again, just a few mm of pull upwards. Then spin again.

By manipulating the tilt capability of the battery plate and monitor arm, you can quickly and easily find a dynamic balance point for the Steadicam Mini and Steadicam Flyer. I've done it with both factory models in addition to my prototype model, which is somewhere between a Mini, a Flyer and an EFP.

The sled is nice and rigid, does well with a running shot and can be spun flat with a bit of work. Enjoy !

No, I do not.

Besides, the writer of this thread asked how to balance a Steadicam Mini- and by design association, the Steadicam Flyer. If I can find a way to link in a photo of the Flyer sled so people will see the parts I am talking about, I will be glad to do that.

Best

No thank you. That's a generous offer, but this is prototype construction and not really material suitable for posting onto the Internet. Surely you understand.
