Yeah the JR does do some twitching, it has to do with the radio system not liking them. I upgraded the radio to a spektrum and now I dont have the issue.
cen doesnt even cover components under warranty
Isn't that amazing, yet they are the self proclaimed #1 in customer service. I have had a CEN Magnum for a little over two months now, and it has been sitting on the shelf for two of them, due to stripped gears, and they want me to pay for them as if its my fault and not the fault of the inferior parts they installed at the factory. They make what they call "upgrades" but they do not change the performance only the reliability issue. I feel they should replace the gears for free but I guess greed over rules what is the right thing to do.
