I used my spektrum last Saturday at an indoor offroad track and it seemed to work fine, but I don't like the idea of wondering if it is working at 100% or not. On carpet I could see where guys could feel a difference because carpet is so precise, in offroad you may not feel it as much because your car is being tossed around anyway through the jumps and bumps, but if it's there it's still got to be hurting you. I too would like to hear Horizon's point of view and what if anything they plan to do about it. Again mine seemed to be working fine and I love this technology, but when you invest so much money into a weekend of racing you also want to know everything is working right.
