I have purchased a revolectrix gt1000 Duo. It was on special and it seems to be a more capable unit and the person that gives support here is really knowledable. I was reading on the hitec here and read a hitec rep stating that the charger could pull 120 amps through a 4mm bullet... In this case product support/feedback made my decision to go with revo and not to mention 5 year warrantied that is doubled by my credit card! In 10 years I would be needed a new charger for any new technology that may come out.
