Loose Prop Quick release

[Jayfdee]

One of my regular checks, well every 10 flights or so, is a thorough good inspection of my craft.
Today after a long mission flight a check revealed that there was some movement between the quick release plate, and one of the motors, there are 3 hex screws, and they were slightly loose, I also re checked all the other motors.
One to watch out for, I am sure we all do this anyway, but this is the first time I have found a problem after perhaps 140 flights.

That's a good tip. Had you ever torqued those screws before you found they were loose?

No, but my manual twist check had never detected any slackness. I check by holding the body of the motor with one hand and twisting the quick release with the other.
There are 2 things I am a bit paranoid about, and both can be fatal in flight. I always double check the battery is secure, and that the props are securely attached.
Happy flying.

You must keep an eye on those mounts

My mounts never got lose from factory to over 3,000,000 feet. I marked them with a line from the screw head to the clip with a fine permanent marker in order to detect any rotation of the screw, no problems yet. If after re-torquing they loosen again I would put a drop of removable locktite on the cleaned threads, don't over-tighten.
