In Europe, Corally is quite big! And I must say, Corally always advertises with a message to serious racers. They have never wanted to be the company you first look at as a beginner... It's not a beginners car, it's a winning car for an experienced racer...
About Batteries and motors, I think Corally is the most honest company out there... For an example, Orion always hype up their equipment, but it's usually not specially better than anything else out there... Corally always delivers great motors and batteries, and they always have numbers just as good as the team drivers...
So in my opinion, I think Corally Usa is your biggest problem..
