I have Two used E Turbax fan units complete with Neu Motors 1527 1.5y motors. These units both have 6.5 mm bullet on the motor leads. Reason, I'm using a different fan size. I was going to use these in a twin and decided to use a smaller fan unit. There are two units so price is per fan unit and motor. No other items are included such as ESC or batteries. This is fan unit and motor as shown.
All specification are listed on Neu Motor website and Jet Hangar. This is a 5 fan unit go for models ranging from 12 to 20 pounds. I have one of these units in a 20 lbs He 162. Speed control required is 110-160 amp controller. Depending on batteries 110-127 amps are what you can expect. Watts 4800-5200 is very much attainable.
