Copterx 450 V4 Pro FBL Build Question

[Crash_Pilot]

Evening Freaks,

I'm currently working on a copterx 450 build. I'm following Finless Bob videos and have connected the servos and got them to 90 degrees. I have the balls() to attach to the servos and can't seem to get them attached. The screws that came with will not fit into the servo horn.

Does anyone have any advice on my problem?

Can attached pictures if needed.

If you push hard they will go in. It needs to cut threads into the plastic.

I tried that but the screws don't look like they are the correct ones.

Those look like the correct ones. I had a helluva time getting them into my CopterX 450Pro build lol. I actually ended up ordering a couple sets of Align's balls to replace the CopterX ones because the Aligns are hex-head, and much easier to use/drive in!

I ended up removing the servo horns, laying them flat on the table to get good leverage, and pushing reaaaallllly hard to start the thread. Worked, but took a lot of effort. I also took my Xacto knife and ran it inside the hole I was trying to get the ball into. Made it much, much easier! Hope that helps!
