Joe, the fan is the Aeronaut turbofan 4000 (120mm) Motor is Neumotor 1912-1y, castle 110 amp h/v esc, ubec h/v , (2) 5 cell lipo Thuder power Extremes 5000 mah. i have ordered the Spektrum DX7 for control. This is a 3000 watt setup and i'm shooting fo a close to 1:1 power ratio. I'm about 1 sq. inch short of fan swept area on my intakes. I am leaving the circular center section (spinner fairing) open to provide aditional air through nose gear door opening. This should have minimal effect on main airflow. My son just put the 3'rd flight on his Jepe A-4 1000 watt setup. What a nice flying jet. we have to do the paint scheme, but we are having a hard time finding the light grey Navy fighter colors in a spray can. I will need the same when i'm ready to paint mine. Doug
