RC4WD 4200XL models and nomenclature?

[TheBennyB]

I orderd directly from RC4WD. Interesting that I have 1.5 lighting but 1.0 block. Also gear aux on TX is still set up to turn lights on/off. How long has 1.5 been available? Odd to still be converting and not starting with the 1.5 block unless they have a bunch of 1.0's laying around hence the price drop? Its not a huge deal breaker, hoe will still operate. Just don't like getting jerked around and I'm hoping to get the 1.5 block upgrade on their dime then convert if I want at a later time.
