so i am sorta new to this RC thing and have been learning and learning about little things about the MERV. So today i installed the pinon gear that came with the kit and hooked up the series connector and put two full charged 1200 mah 7.2 volt batteries (just the stock ones, i have four.) and then powered the car up. The ESC then started blinking red and green at me and i dont what it means. I tried the two other batteries and they did the same things. The car runs amazing in the paralell mode and i love it to pieces i just wanted a bit more speed out of it and was wondering if you could help me figure it out thanks!!
