The packet contains the two cross struts shown. In order to test this undercarriage the plan was to assemble it onto some skids and then basically abuse it with the intent to break it. The struts fit nicely on the standard Align skids and can be secured in place with a small application of CA to stop the skids from spinning round.

Having built the undercarriage I subjected it to various "squash tests", these involved either slowly or quickly pushing down on the undercarriage to simulate a very hard landing. The skids bend outwards under reasonable force but show no signs of wear and tear. Letting go the struts move back into shape, this happens more slowly than the Heliup undercarriage. Also considerably more pressure is required to squash these skids flat than the Heliup skids.

Next job was to jump on it, which it also survived, although I was expecting it to break. The elasticity in this plastic is definitely less pronounced than the Heliup skids and my expectation is that between the two the Heliup is probably more likely to survive a severe crash as it is a more elastic and bendable plastic.

Overall I feel these struts are a vast improvement on the original white plastic and will most definitely survive the majority of hard knocks. Given a choice I would buy these struts over the white plastic ones everytime.

Below is the new T-Rex Tuning rating system. If you already own these struts please feel free to rate them.
