It depends what your looking for in an RC. the KG Racers don’t seem to be modifiable, nor are the Digi-Qs. The Bits and Z racers are, but the price gap is pretty big. For price vs. cost, avalability of parts etc, I think Bits are the way to go. If your looking for a more serious rc car, then spend the extra bucks on the Z’s.
Just my thoughts on your question.. :smiley2:
