Goblin 630/700/770 Skid Clamp Assembly (Black) by Random Heli
This is the Random Heli Black Skid Clamp Assembly. This assemble is specifically intended for use with the SAB Goblin 630, 700 and 770 Class Helicopters. These clamps can be fastened down to create a safe base for securing your helicopter during storage or transport applications.
How 'Goblin' Skid Clamps Work
The Carbon Fiber skids rest on a 45° 'ramp.' Attack self-adhesive grip discs (included) on the ramp to accommodate variations in skid thickness and provide a snug fit. Press down just forward of the logo on the clamp to close the skid clamp. The latch boss forces the skid down onto the base and 'ramp' and captures the bottom edge of the skid, preventing twisting.
Holding Strength Video
This is the first of three performance testing videos. It focuses on the smaller Clamp, the STC5560 but all three Skid Clamp models were tested on the same test rig. Despite significant deformation of both the Skid Clamp latch and base, we found that a single clamp can hold more than 3 times the weight of the heli it's designed for. Since your heli will likely be secured by a set of 4 clamps, that ought to do it.
Impact Strength Video
This is the second of three performance testing videos. In it both the STC5565 and STC9000 Skid Clamps are tested. Results indicate that both models can sustain repeated impacts of more than 10g. Putting that force into perspective, it's just a bit more than sending your heli straight up 300 feet in one second.
This is the third of three performance testing videos. In it both the STC5565 and STC9000 Skid Clamps are tested. Using a purpose built test rig, the clamps are cycled >10,000 times in 5 hours. By the end of the test, the latch mechanism is less stiff and the grippers are somewhat relaxed. Yet even after 10,000 cycles, both models securely hold the skid tube when latched and both retain more than 75% of their original holding strength.

Video Note: Videos are for demonstration purposes only and do not feature the Goblin specific clamps, but holding strength and cycle durability still apply.
Mounting Note: In order for the CF skid to fit snugly against the ramp feature of the Skid Clamp base, the Skid Clamps should be mounted square to the CF skid. For Standard skids the Clamps will be in line with each other and form a rectangle. But for the low profile and competition CF skids, the Clamps should be mounted with the inboard mounting screw offset toward the tail of the heli. In all cases, the object is to mount the Skid Clamp square with the CF skid.

Thankfully they also fit perfect with my Trex 600e with the Lynx carbon fiber landing gear.)
