Ok I still would like to know is the other speed passion capacitors that you can buy are better then the stock ones that come with the gt pro v2. Ok next question. I just got the lcd program card. It says to use between 4.5 and 6.5 volt. I have a 2 cell lipo that is 7.4 volt. So can I use my lipo or do I need a extra power source. thanks for the help ahead of time.
