The dead zone thing that was brought up is with the steering, the throttle can be adjusted to zero dead zone within the software. For whatever reason they have I think a +5 as default for throttle. The internals of the Pro and Normal NB4 is identical, with the battery base being different as it has wireless charging built in. The Pro battery will work on the regular Noble NB4 and wireless charging will work without any other changes. It's got a fancy aluminum case, and is a bit more premium, but nothing really different internally.

I think it has to do with quality issue with the steering mechanism as the Pro uses the same hardware, and if there was no issues with the Pro as some people have stated then there is no reason the regular Noble should have the issue other than an issue with quality control of the said part. As I said, myself, and many others do not have this so called dead zone or dead area in the steering. I have discussed this also with local NB4 users as well. Highly unlikely it is a software issue as the people I spoke to owned the Noble NB4 when Razor had posted his review on it. So I think it has to do with the supplier of the steering mechanism, and quality control.
