Default RE: Electric motor selection

36 inch span and 18 pounds. maybe a nice JATO from a C130 will fly it. Average 36inch span plane is around 1 pound or less. From the weight you listed the span should be around 65 to 70 inches for the listed weight. A plane of 18 pounds is going to have a longer span.

I think you need to change your design some. Check the specs on a 60 sized trainer and compare weights with it and what you want to do.
