Good morning everyone. We posted here some months ago about this product. But, we figured a fresh thread would be appropriate. We are shipping these starting this coming Wednesday 6/03/15. We already have about half of our first batch spoken for from those who have been waiting for our release, but there still are units left! Everything you need to know is listed here on our product page: http://www.catalystmachineworks.com...multirotor-arms-for-cinestar-or-similar-craft But, if you still have questions please feel free to contact us at firstname.lastname@example.org or just post here. We recently ran load testing for the C25 using a 550mm arm up to 20 LBS. This is 20 LBS on one arm... The 550mm is the distance from the far interior edge of the C25 coupling to the motor output shaft on the end of the arm. Once we finish producing the load test video I'll post it up here. Looking forward to fielding questions. Cheers!
