I have a Jammin X1CR-FTE that I plan to race. I would like more out of my servo's and want to know if it's advisable to change the receiver pack (1600 nimh) to a 2C lipo or 6.6 Life receiver pack (Hobbico sells the latter - 6.6V 11 mah battery) If Lipo, I would prefer not have to use a voltage cutoff unit if possible. Would my servo's be able to handle the higher voltage. As to the Life pack, I think this would be a direct "bolt on" and would not have to worry about frying my servo's. I currently have older servos.... KO Propo PS 2173FET for the throttle (111 oz. @ 6 volts and .09), and a JR Hi-torque digital Z9000T for the steering (300 oz @ 6 volts and .15 speed). How much faster would my servo's work using a lipo (2C) and the Life unit described? This might even be a way for a budget racer to enhance his servo package for a nominal cost? What say you?
