[6.9 x 4 x 3.1"] I have used it and it is very versatile & heavy duty. Works well with my cheaper light stand. It is very heavy.

[6.9 x 4 x 3.1"] This is the best light stabilization system that can support Red cameras, Arri Mini Alexa, BM 4.6k, Sony Fs7 or Dslr cameras with cage, heavy lenses and external battery, that is, with all its accessories together. It's better than the Ronin M, Ronin 1, Movi M5 and I tell you this because those teams are very heavy that need external arms, easyrigs or steadys to not tire after a few minutes. Apparently the resistant magnesium of the Helix, lightens all the equipment and its engines are powerful. I would put it a little less at the level of the Ronin 2 and Movi10 because those teams are already another type of similar systems and equally heavy, but popular. The Helix is quite portable and easy to calibrate on a flat surface. Always use the Helix application on your iPhone that simplifies everything, because entering through usb to basecam, that is very technical and complicated. Everything is connected through Wifi and Bluetooth. Do not buy the version with RC because I personally would not use it. It is a remote control that is purchased separately to move the Helix and I suppose it would be used to put the Helix on a car or drive it from a distance and I do not do that. If you are going to use movie cameras, make sure you have 3 batteries, because the Helix feeds the cameras through specific cables that are on your website. And also the same battery powers the follow focus through D-Tap. It has been a good buy.

[0.65 lb] Everyone should have this sturdy stand adapter it tilts and puts my Chimera Softbox where I need it with no problem.

[Aluminum] It’s been almost one year since I bought this product. I was skeptical first since there aren't many reviews of this product and it is one of the most expensive camera stabilizers in the market.
Like, I said it'd been almost a year now, and I had an opportunity to use Letus Helix on plenty of wedding events...and the more I use it, the more I am falling in love with this gimbal. It's very easy to setup; you can set this on the ground quickly change lenses and adjust very quickly. Doesn't take too much of time to bring it back to balance. The encoder motors work great. I love the briefcase mode.
I mostly use Canon C100 M2, but this gimbal easily handles my C300 M2 with Canon 16-35L III lens or with the 24-70L lens.
I had to practice a little bit to get stable footage, but I had never used gimbal in my life, the learning curve for me was minimal, a couple of hours of good practice is good enough to start getting good footage.
I looked into purchasing another gimbal in the markets, but I like the form factor of this gimbal - holding at eye level has its advantage. Customer support is excellent. Overall, I am glad I purchased this product, I am pleased with it, and I am highly recommending to anyone looking to buy Letus Helix with encoder motor. It is one of the best gimbals in the market now.

[Aluminum] A fool purchases twice, I purchased twice. Do yourself a favour and buy the chimeras, they are more expensive as they are made to a standard, not to a price. I use them to hold Westcott 7 ft umbrellas, they do it with ease. This is a serious piece of well engineered equipment, I gave away my old equipment and ordered three more but the double axis type. You can't get better ... period, don't be a fool like me, purchase once and purchase the best, Chimera

[Aluminum] Very well made product by Chimera. Heavy duty. Even while being tilted, rotated and spin it is capable to sustain quite heavy load.

[6.9 x 4 x 3.1"] Due to a wedding gig, i required a Wescott 7 feet umbrella to take group shots. The normal flash and umbrella mounting could support the weight of it. So I knew B&H would offer me something that would do the job. I read from another review that this Chimera single axis stand would do the job. So purchased 2 units. Came shortly in 2 days. I found that one of the parts that was supposed to in was not there in one of the unit. Sent email regarding the matter and without hesitation B&H responded and sent the part. I am extremely happy, B&H you got yourself a loyal customer now! Cheers!

[Aluminum] I use this adapter to connect my Chimera Super Pro Plus Softbox to a boom stand. Rock solid is what I need and what this adapter delivers.

[0.65 lb] We have used 3 Helix units from Jr model to full size Magnesium models. Unlike ALL other gimbal systems, this one can be held easily at eye level and is lighter. It also does not need a stand like all other gimbal systems as well... You can just it down on a table or the ground and pick it right back up again. The design is GENIUS. As far as the previous review, I'm sorry they had trouble with it but there is a LOT of documentation on the website via manuals, FAQs and training videos! Software and firmware updates have made this gimbal rock solid and it has run PERFECTLY for us on every shoot.

[0.65 lb] This is an amazing Rig. Being that it's a little less used than the movi or ronin, you need to find custom solutions for cabling when using a follow focus system. It is very stable once you get up and running and Letus now have a website for the rig (letushelix.com). It's very easy to balance and the weight centered on the lens so switching lenses is easy and requires a minor adjustment to the bottom plate. Must haves, Monitor Solution (Small HD 502), Follow Focus (Red Rock Micro Remote Focus). If you get all of these solutions you will spend about $ at the end of the day, but hey, can you run with an 85 mm lens on a glidecam and keep it in focus?
