Feigao 540 9L and Warrior 9918 Controller

[MadDog]

I just received my Feigao 540 9L and Warrior 9918 Controller.

After getting it all wired up (LHS did it for me) I installed it in my e-maxx. It seems to be doing some weird things and im not sure if its normal so that is why im posting on the forums.

Now my questions are:

Is it normal for the motor to make a weird noise when barely giving it any throttle? The motor doesn’t even turn, it just kind of kicks a little and makes a high pitch noise. (ive never seen any other motor do it before, but ive never owned a brushless motor).

Is it normal that the back of the motor cover comes off after a run??? I noticed it came a little bit off after my first run. I poped it back on but how do you stop it from coming off??

Is it normal that sometimes when at a dead stop and you give full throttle nothing happens but a little jerk on and off?? (does this off and on, both in reverse and forward)

Is it possible that the motor or speed controller is dead?

p.s. I followed the install instructions to the letter. It does run good sometimes, but i have the problems above.
