Hi Indian 007 you could probably get a brushless motor to fit but i have read alot of posts stating that they have experienced what is called brushless bounce back and it makes it harder to fly the heli. while i'm no expert i do believe most of what is said about the subject. Most of the guys went back to the brushed motor. You might check your esc to see if it is feeding to much amps to the system . While the brushless main can handle it you could be feeding to much to the tail. I hope this helps out. Good flying and good luck.
