Hi All,
Hope someone out there can help. I am new into this game so please be patient... ????
Bought my first glider a Kunlun 200, really going well until a strange noise comes from what I think is the motor. Best way to describe it is a cracking type sound.

Tested the motor prior to flight as well.
Three things I notice....
1. The motor does not come to a complete stop, it runs a very low rpm making the crackling sound.
2. When I stop the motor by force (lightly touching the cone) it won't start up again.
3. I disconnect all power then re-connect, do all the pre-flight tests then find all is OK again including the motor. Until the noise starts again.

When the motor is running it sound fine, there is no warning at all...!!!

This is what I am running....

Motor JP Energ Brushless 560 0/R 1100 (C35-20), using a Ripmax Dragon 2S-6S Li-Po 6-20 Cell 45A ESC. I am running a 25C LiPo 2200 mAH 11.1V 3S battery.

Can anyone help!!!!:confused:
