hey people.... i have a hyper 7 less than 3 weeks old and all of a sudden i have realised that i have no brakes or 30% of what they used to be. I have adjusted the collars on the linkages but still no improvement and i'm using a fully charged 5 cell intellect 1400 ma pack for my RX......where else should i look or am i just up for a set of brake pads on it already?
