Q: 1. The Matthews MINIVATOR II 142 will fit in this one?

A: Yes

Q: 2. What is the load capacity at maximum extension for this boom arm?

A: The maximum load capacity at the maximum extension on the Matthews Junior Boom is 25 lbs.

Q: 3. Is this stable enough for camera use? Can it have a PTZ on the end of it for example and not sway or shake when the PTZ moves around?

A: The general rule is that what you put on the boom should be half of the boom's support weight. Which is 20 lbs. So, a camera with the lens really should be 10 lbs. or less.

Q: 4. A review mentions using the boom to attach a DSLR for overhead photos. What adapter is used to attach a camera?

A: Hi Jeff, I attach my manfrotto tripod head to this adapter. https://www.bhphotovideo.com/c/product/1046652-REG/matthews_350625_baby_pin_adapter.html

Q: 5. How tall can it set with the boom arm out ?

A: The boom arm on the Kupo 546M K Stand Junior Boom Stand can extend to 61-110 inches.

Q: 6. Is it a 5/8 baby pin for the light stand connection?

A: Yes, there is. The pin under the center of the arm is a 1-1/8 inch junior connector, but under that is a 5/8 inch baby receiver. I personally recommend using the larger junior connector for its strength and support, especially for booming heavy items or when the boom arm is fully extended, but it does have the 5/8 receiver if needed.

Q: 7. Is it possible to lower the center column to the ground in order to improve stability with a forth point of contact and also to make the minimum height less (just like on a regular combo cine stand)?

A: While it may be possible for the center of the light stand base to connect to the floor, the Kupo 546M K Stand Junior Boom Stand would not be the most stable in this configuration. It would be best to have the legs spread out to the maximum width, and you may use the boom feature of the stand to boom the light fixture to a lower height than when the center column is used upright.

Q: 8. what is the max extention on the boom arm?

A: The boom arm of the Kupo Junior Boom Roller Stand (B&H# KUKS301512) at longer extensions will typically require a counterweight (e.g. a sandbag like B&H# IMSBFO15) and the degree to which it may be extended will vary by the relative distances from the point at which it attaches to the stand and those of the counterweight, on the one hand, and light (or other addition), on the other. Although the boom arm is about 60" long when fully extended, it should not be used at full extension and counterweighting is essential.

Q: 9. When completely collapsed and laying on its side, how tall is it off the floor? I would like to slide it under something in my truck.

A: The lowest profile of the collapsed Mini Max is 6.25" tall(laying on its back). Laying on its side the height is 7.25" due to the rocky mountain leg t-handle sticking up.

Q: 10. Can i use it with the stand (Matthews MINIVATOR II)?

A: Yes
