BRUSHLESS DR. SPEED7T delta w Graupner 97257 With the new BRUSHLESS Dr. SPEED motors GM-Racing has succeeded in developing highly efficient motors which set new standards in terms of reliability and power.

Multiple extra-thick windings together with extremely low-loss construction and sintered neodymium magnets for enormous power and high efficiency
A thicker shaft ensures more accurate true-running of the magnets
Cooling openingsmaintain favourable motor temperatures even under ultra-harsh competition conditions
BRUSHLESS Dr. SPEED motors feature sensors and a sensor connector, and can therefore be operated with GM-Genius speed controllers with and without sensors. This means that the annoying sensor leads can be eliminated for even higher reliability
Variable sensor timing
High-performance ballraces for high revuluttions
The motors comply with DMC rules and EFRA rules.
