250er Copter Antriebsset Eins Graupner 16550.1

The low-cost

The 250 class copter drive set for beginner is suitable for all of those who just start the multicopter hobby. The set consists of 4 Brushless motors, 4 ULTRA CONTROL 12 A speed controllers as well as a set of 5x3 inch Copter Props.
The 4 Brushless motors of the Graupner ULTRA 2804 2300 kv Brushless series with 2204 stator (No. S7047 & S7048) are characterized by their low weight and high torque. The motors are very compact and lightweight, but have 4.5 mm magnets and 14 poles. The special multi-winding ensures optimum effect and cooling. The set contains 2 motors in direction of rotation CW (clockwise) and 2 motors in direction of rotation CCW (counter-clockwise).
The 4 ULTRACONTROL 12 A speed controllers (No. S3055) have been specially developed for Copters. The 11 gram light brushless speed controllers are distinguished by the special multicopter software with particularly fast response times. The internal BEC eliminates the need of an external BEC.
Also included are 2 pairs of copter props of the size 5x3 inch (No. 1348.5x3) from the Graupner C-PROP series. The C-PROPS have also been specially optimized for Multicopter. They are particularly stable and have a high efficiency. The Graupner C-Props have an extremely thin blade profile and they are extremely light.
