Hello Hingerty,

The motors I am using have cap on it as a tighteing screw over the propeller. And I tight it to the extent it becomes good tight. I wonder if tightening screw really affects this much.

I have got another doubt. Is it necessary to keep the quad in the same position as I kept in the position of calibration?

In other words, if, at the time of calibration, I have kept my quad front facing east (for instance), is it necessary to keep the quad facing east at the time of trial flying take - off? I understand that, this should not be the issue for toppling. But, still I just got this as a doubt.

Thanks for helping, Hingerty. I appreciate your input. Please keep on helping and share the solution for the question. Thank you

Hello,

I calibrated my CC3D autopilot on my fpv quadcopter. But, it topples on its left or right the moment I try to take it off. I checked the above given conditions and troubleshooting, but everything is fine. What can the probable issue with it?

Please help me.
