42065 was one of the best selling Technic set, I recalled having read somewhere so. Can't really blame TLG for not capitalizing on that taste of the customers. And I think remote tracked racer is more fun than remote wheeled one. Probably because of that funny sound the tracks made when running in high speed.
I was so tempted to ask Milan if he worked on the new racer, but I kno too well he won't answer that question at the moment, and asking so might annoy him.
