N30 model aircraft motor propeller suit suit double motor [Motor voltage]: 3-6V Length 25.5mm Diameter 14.1mm Weight 5.5 grams KV 3000mm Shaft 1.5mm Lead length 50mm Contents 2 x Motor 2 x Propeller CR (cw ccw) The N30 is a great reliable workhorse of a motor which features long life and solid construction. Although the power to weight ratio may be slightly less than geardrive setups, many people prefer the reliability of a direct drive system. See our test data below. This motor is supplied with a 75mm propeller which gives good all round performance and it allows the motor to be run from a 3 amp brushed ESC unit or directly from many brick type receivers. The supplied prop also has a bore which goes all the way through allowing you to reverse the prop on the shaft for a pusher prop configuration. You will need to sand the terminals with some sandpaper to allow for easier soldering.
