Do you Loctite your Screws on your drone?
#1
Hey guys 
when building your drone do you have to put loctite on screws or does it matter?  Huh

Is it a must have ? I've got some coming haha have to take the motors off and put back on

Just tighten All your nuts, bolts and screws to 48nm and you'll be fine....

I've flown without it many times - I include checking everything is right pre-flight. Nothing has ever failed. My flights only last 5 or 6 minutes. I never use it during maiden or subsequent test flights - it encourages me to check and recheck.

By the way, You don't need loctite on nylon nuts, only on metal to metal connections, like your bolts into the motors.
I love to share and help people! Flying Mini Quad is the best!

Loctite on any metal parts. Aluminium stand-offs, motors. Unless it's nylon, because plastic is self locking
I also read somewhere you can just use clear nail polish, works on plastic too hehe Big Grin

I always make it a habit to use blue loctite (never red), the amount of vibration and flex running through the frames from the motors/props during flight make it hard for the screws to stay tight all the time. I've learned the hard way a few times of the consequences of things coming off or loose in flight (you'd be amazed at how much the wrong loose screw can throw off tuning/setup). Its not a big deal if you don't mind going over every screw before each flight but there are cases when that's just not possible, especially if your at an event or meetup. As the others have stated just use it on metal on metal contact but it will save you from having to dig and find missing parts or worse when they do come out. Alot of people don't bother with it and I used to be one of them but it adds a level of security to ensuring one less thing can go wrong.
If it isn't broke, fix it anyways!

I loctite all my motor screws, and bottom plate screws to standoffs, as I have come back after some flights missing bottom plate and motor screws. People really do not think about the amount of negative and positive G's the mini quads pull doing acro, which puts a lot of strain on parts. For the small outlay and little time it takes to do I believe it should be high on your list of things to at least consider.

I always do. But I didn't know it wasn't needed on nylon - thanks for the tip!

I loctite every screw except the motor ones cause i'm afraid to get it into the motor Big Grin

Nevertheless after every crash/repair i check every screw!! I think that it more important.

Anything metal on metal in my quad gets threadlocked.

Definitely do the motor ones! I mean they're extremely important. You only need a tiny dab on the edge of the motor screw, then screw it in. There is no way it'll get into the motor.

I haven't yet but i have lost a few screws white doing test flights etc. So it would probably be a good idea for me at least

I come from heli flying and with a metal frame and a metal head you HAVE TO USE loctite or see your head explode mid-flight  Big Grin

And yes, I speak from experience  Angel

I'm using locknuts for mounting props on my big tricopter. Once I was too lazy to apply thread-locker on them, after 5 minutes of flying the tri fell from the sky and was damaged quite badly. The locknuts on CW-spinning locks came loose and lost thrust :-)
After failing miserably like that you quickly understand the third Newton's law and other useful theory :-D
