You are talking about BLH4543 kit.

I couldn't find some detail of this bag contents.

I saw some self tapping screw and some M3 hexagonal bolts...

Yes, that is the kit, but I wanted to know the size socket head cap screw,
I think they are 1.5mm but I do not know the pitch of the thread, I could order some from amazon cheap!

When we say, for example, M2.5, metric, this is an standard.

See this table...

Did you see the chart they got M1.4 and M1.6 but no M1.5, so that is why I would like to know what Blade helicopters use, M1.4 or M1.6?P.S. sorry for the spelling or the grammar I am dyslexic!

1.6 seems to be the common size. MicroFasteners, BoltDepot, and
FastenerExpress start at 1.6mm.
1.4 and 1.5 not even listed.

And yet the Micro Fasteners metric (and SAE) sample blocks has 1.4 and 1.5 in the metric block.The older I get, the fewer things seem worth waiting in line for.

I contacted product support at Horizon Hobby, quote
Most of the screws used in the 300 CFX are M3 machine threads of varying lengths.
I think that there is not one M3 screw on the helicopter?

You could..under magnification measure the distance between the thread crests...I checked a couple of my micro thread taps..one is 2mm x.4 pitch..another is 2.5mm x .45 pitch..your screw should be one of these..I do a great decending funnel!
