Performance Testing RC Heli Storage and Transport Skid Clamps Truly remarkable performance from a couple bits of plastic Holding Strength![]() Before you trust your heli to Random Heli Skid Clamps, you ought to know how strong they are. A 90-size nitro heli weighs about 10lbs. Single STC9000 Skid Clamps were tested to three times that figure. Impact Strength![]() One of the features that make Skid Clamps unique is the latch. It prevents the heli from coming loose if your car hits a bump or pothole. All Random Heli Skid Clamp models withstood more than 10g. Durability![]() If you clamped and unclamped your heli once a day for 27 years you'd be just short of 10,000 cycles. That's the figure we used to test the durability of our Skid Clamps. Holding Strength VideoThis 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 VideoThis 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. Durability VideoThis 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. |
