Title: rc helicopter help!! Post by: javed hussain on December 02, 2017, 03:51:11 PM Hi,
I crashed my 450 heli. But i don't know why my heli is crash. My heli started rotating automatically in one direction and goes out of control. I fly heli just minute before then it was flying nice but in second time it create problem. I checked my gyro and it in 75%. And the gyro is working good but i don't know what is problem. Please help me so i can understand problem of my heli. Did it cause by grass which is touching on tail blade. This is link of my video(https://youtu.be/mGbb7qgjf7E) please see and help me. Thanks.

If torque tube instead, verify the tail gear is not stripped.
