I have a prototype built of a Rotarywing Aircraft.The 6ft. re-inforced foam lifting wing Is rotated fromthe wingtips.I am currently looking for the lightest motor that I can find? and a speed control that will control both motors.When I find the motors I am looking for I can choose the props.Any suggestions will be a great help.The rotating wing is also6 inches from lead to rear edge Charlie111 p.s. something equal to an 0.20 or 0.49 would be plenty.I heard they make a pretty good electric motor that only ways 4 ounces I don't have the numbers to give you right now.But; Like I said any imfo will help!
