I'm happy to inform you that we have some RCP Link-N-Rocks on the way to us. If you have seen a shot of our track from the shop cam you'll notice that we've reconfigured it a bit so the infield is wide open. That will be the new home of our RCP pre-fabed rocks!
In addition to RCP's track products, they are in process of manufacturing modular rocks for the RC crawling industry. The rocks can be used for in store display of RC crawling trucks, in store demo purposes of RC crawling trucks and set up for RC rock crawling competition courses. They can be used in the home, office, hobby store or corporate/trade show event. They are rated for both indoor and outdoor use and weigh less than 8 lbs per rock pod.
The rocks are made through a special process that gives the texture a realistic look and feel. The rocks offer excellent grip for all types of RC crawling rubber tires. There's nothing like being able to test out your suspension setup "indoors" before you hit the rocks at the comp!
