I know no German but this is what BabelFish translated:
GM BRUSHLESS EVO 2 engines GM Racing states the RC Car brushless Technology. GM Racing uses thereby the already over 6 years long experience within the range of the Brushless engine and automatic controller technology. With the new BRUSHLESS EVO 2 engines is to be developed GM Racing successfully after the DMC regulation high-efficient and low-priced engines, which set new yardsticks in reliability and achievement. Extra thickness mehrfachwicklungen as well as an extremely low-loss Design without unnecessary conductive strips and temperature-firm neodymium magnet provide for achievements of clear over 270W. Thus the GM Racing reaches BRUSHLESS EVO 2 6T and 5,5T engines achievements and efficiencies, which are not for a long time reached by brush engines because of the heating. Without the expensive, shock and temperature-sensitive resounding sensors and unnecessary inlets of the sensors was done, in order to reach a clearly higher reliability. Nevertheless together with the GM GENIUS of 80 travel automatic controllers an automatic controller action was reached that from conventional automatic controllers for brush engines in nothing is inferior. The "slotted" Design of the stator ensures for a handling that corresponds to that of a conventional engine. The BRUSHLESS EVO2 IFMAR SPEC is equipped with sensors and has higher numbers of revolutions with fewer torques. Victory of Markus Mobers with the Graupner anniversary running. 5 of 10 A-Finalisten used that GM brushless system.
So unless BabelFish is wrong, it's sensorless brushless motor, so 100% not OEM by either LRP nor Novak, but probably by Graupner?
Very interesting indeed...
Btw, if you check Graupner's website.. wa.. 4.5T listed...
