hippie, how big is the american enterprise? and how heavy is it? im a bit worried that the mini jet drives might not be enough. i am currently working on a semi-scale patrol boat 1meter long x 16cm wide, and using 2 mini-jets from graupner, with 2 tamiya sport tuned motors. i tested it in a tub using an astroflight 212d esc and the esc barely got warm. i then tested it using a tamiya adspec (the adspec is designed to be used only with one sport tuned motor) it got warm a bit, but not really hot. both test using 7.2volts. hope this helps somehow.
