Graupner,EVO one 50 7,2 V,6510

EVO one 50 7,2 V Graupner 6510 The new EVO one 50 SENSORLESS motors are extremely light in weight at only 133 g, and therefore form an obvious alternative as compact high-performance power plants for small model aircraft and boats. The dimensions of the shafts and fixing screw holes match those of the SPEED 400, 480, 500 and 600 motor series, making it straightforward to fit these motors as direct replacements in existing models. In common with the already popular CARBON 70 motors these new units offer the following advantages: Optimum efficiency in conjunction with mc-BRUSHLESS CONTROL 45 SL speed controller, Order No. 2878 or GM SPEED COMMANDER BEC, Order No. 94131. Aluminium or CARBON cases for minimum possible weight. Extremely low motor volume and consequent excellent power / performance density, due to elimination of sensors and connecting wires. No parts subject to mechanical wear apart from the two high-performance ballraces on the motor shaft.
