The B20 18L kv3086 + 4:1 was specially developed for glider models from 800-1000g. The slim design and 4:1 gear reduction mean you get 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
