This base clamp fits the rib channel on any Robinson R22, R44 or R66 helicopter. This clamp can be easily tightened by hand making it a FAA temporary mounting device. The thumb screw also has a hex drive allowing you to use the included hex wrench to tighten a little extra if necessary. This clamp also fits and 3/4″ steel tubing. This clamp uses the metal Gopro adapter for any Gopro Hero 2, Hero 3, Hero 4, Hero 5, Session, Garmin Virb X and XE, or any other Gopro style cameras. Simply rotate the camera and lock down the jamb nut with a 7/16″ wrench.
Recommended to use the GoPro safe metal case to eliminate the common problem of falling GoPros due to the plastic GoPro cases breaking.
