Sure. But basically, all the subjects are getting cut off.

Gaza - can you make the subject line section in the forum topic list wider? It's cutting off the subject field really short.

Just had a thought, even with all the crashing I've done, I haven't bought any replacement props in over a year ~~

Watch out that your Frame screws aren't coming loose!

After a couple of gentle hovering flights this weekend I noticed that one of the screws holding the arms on my quad was almost out.
No idea how it had unwound itself but it had; cr4ppy little torx screws no threadlock had been used.
Engineering fix required,  m3 x 6 screws + shake proof washers.
I think..........I think I am........therefore I am.............I think!

DarrellW,

Really like this! Are you using a DJI clone or the real McCoy? Where did you get the screws from?

Cheers

It';s a clone (no DJI on the arms).
The original screws have a shoulder, your arms "could" be miss-aligned. You could use 2 original screws at a diagonal to centre the arms, fit 2 new ones, then replace the remaining originals with new.

I';ve had a couple lost, so as Darrell advised it';s best to check and loctite them in.
If it';s M3 x 6 you';re after, they are a couple of quid for 50 stainless machine screws on ebay.

DarrellW

I don';t use Loctite on that sort of application because if it';s stubborn when it has to come out the old trick of heating the screw head with a soldering iron could cause the moulded in inserts in the frame to give way, the only thing about using my setup is that you need to make sure not to over-tighten - the shoulders on the torx screws are as much for stopping you over-tightening the screws as they are for positional reference; so I still think my fix is better!
The screws can be purchased from Modelfixings or maybe B & Q; I don';t have to buy stuff like that we use lots of those sizes at work  :evil
The other obvious benefit is that cross head screws are much easier to find than Torx heads - those are mainly used by White goods manufacturers to stop the average bloke in the street taking things apart  :rolleyes:

Good place for all sorts of screws.
MODELFIXINGS.  Google it.
Takes Paypal.

A dab of nail varnish on the threads is a good fixative and then the screw is easy to remove if required (as apart from people using the imcorrect grade of threadlocking liquid)d some of which holds extremely tight and makes life difficult when required to remove.
Cheap as well.!
Let's be careful out there.
SAFETY is.. NO accident.

AM556

I use Loctite 222 for things that need taking apart and 271 for anything that will be permanent.
