This mount allows you to attach a GoPro camera to the skid of a model helicopter. It has been designed for an Align T-Rex 600 Pro, but in general it should fit any skid tube with a diameter of 9mm. The mount is engineered to allow the use of standard GoPro mounting hardware and accessories. Please keep in mind that since this is a fixed mount if you have vibrations in the heli they will translate into vibrations on the image.
The mount should be able to withstand basic acrobatic manoeuvres, but as you probably understand, I will not take responsibility for any loss... If you're looking for more robust mount, please checkout my 9mm Heavy Duty Camera Rig, found here
