RE: velineon or mamba
I think you are missing the point, it could be the best system in the world, but it would still fail due to the price tag. This is an RTR kit we're talking about, no newb is going to pay that much for a truck, and an expert will know you can get the same truck and upgrade it for cheaper. Traxxas could have had a real winner here, but for that price the rest-of-world is never going to know or care. No one can in reality say it's good or not b'cos no one has tried it for real.
