250er Copter Antriebs.Wettb. Graupner 16550.2 Open to anything
The package comes with 4 ULTRA 2806 2300 kV brushless motors (2206 stator). The hand-wound brushless outrunner motors have a special multi-winding which guarantees optimal efficiency and cooling. Thanks to the compact design, the high-performance motors have an optimum power-weight ratio. The Graupner ULTRA Brushless Motors 2806 have installed 6 mm magnets and thus ensures a fast response, which is a prerequisite for a crisp flight behaviour.
The set contains two left-handed motors, clockwise (CW) (No. S7049), and two right-handed counter clockwise (CCW) motors (No. S7050).
Also included are 4 Race Copter speed controllers 20 A Race (No. S3056). The compact controllers with their low weight (7 g each) have been especially optimized for Race Copter. The Open Source BLHeli software is installed. The built-in Silabs 50 MHz processor delivers maximum performance. Furthermore, the 20 A controller has installed the highest quality FET amplifiers and ceramic capacitors, which allow fast start-up times as well as precise flight manoeuvres. The Graupner ULTRA Brushless Control automatically detects normal (PPM) receiver pulses as well as OneShot and operates with active brake (damped light).
The set is rounded off by four 5.5 inch Copter Props (No. 1348.5,5x3). Two sets of right-turning and two left-turning props specially developed for Multicopter are included in the package. The Props have been optimized for a particularly stable flight behaviour, running stability and high efficiency.
An external BEC is also required to operate the drive set, e.g. the Graupner Voltage Module with SBEC 22.2 V for HoTT (No. S8446).
Included in the set:
2x Graupner Ultra 2806-2300KV CW (No. S7049)
2x Graupner Ultra 2806-2300KV CCW (No. S7050)
4x Graupner Ultra Control 20A Race (No. S3056)
4x C-Prop 5,5x3 (No. 1348.5,5x3)
