Hello I am brand new to this hobbies. I bought the RC off someone that was moving for $50 and it has a mambo brushless motor so its pretty cool. I had to buy a new receiver I got the dx2e spectrum. The problem I am having is I am turning it on and for like ten mins or more I have glides in the signal so it won't drive right at all. And after ten mins it will start to work just fine what do I need to check or do ?
