I would be interested to hear your thoughts on your motor setupyours will be heavier than mine but still I will be around 36-40oz. I'm seriously considering waiting until I get the plane, and weighing everything I have and estimate motor/batt weights before making a determination of the total flying weight. I have digested so much about power from people telling me I need a 250w to a 400w motor, to people saying it cant be done, the Pread. just does not have the room. I'm going to do it even if I have to rebuild the airframe
