B20 15 L kv3700 + 4:1 was specially developed for glider models 800 to 1000g. The slim design and the gear reduction of 4:1 provide you with a very robust and durable motor. Many of our customers have been using our internal rotor motors for decades. With a weight of just 69g and a 3mm shaft, this internal rotor can be installed in many slim hulls. The geared motor is fastened with 2.5mm screws. Please note the maximum screw-in depth of 5 mm, using a screw that is too long will damage the gearbox. Speed Controller 20-30A
