Not sure if anyone is still out there on this engine. I picked up a 26gt without instructions, and what I got off the Horizon site didn't really tell me what batteries to use with this engine. I prefer nimh, but I don't know the requirements. Is it 6.0 volts? Is this the default setting? My ignition is missing the "jump plug" and the led. I am not a fan of lipo's, but what C rating is required? Do I have to reprogram the ignition for the lipo?
