Advice needed regarding carbon blades

[Newbe]

Hi I brough two lots of carbon blades compatible with FC40 and the CW blades does not fit?
Can you help please.

I had the same problem in the past, if you look in the screw hole, take an exacting knife, trim excess carbon from around but insert, they might still be TIGHT, but will go on. I quit using them myself, I use DJI stock props now, no issues, plus those carbon ones are a ***** to true up!

Hope this helps

It's a 'sign'.

Don't use them.
If you must use 'Carbon' use only the DJI carbon reinforced type.

There are numerous threads regarding this.
