I was planning on generating power from a turbine (fuel) and using it to power the two giant brless motors.Possible need for batts. at idle, definatly for startup.Seems brless motors would make alot more torq on the low end,and definatly easier to counter rotate.Just don,t like the idea of a tranny behind a turbine,or the cost of TWO turbines.I need 4500 rpm to be a go fast guy though.
