How are you riveting them?
I found if I wasn’t VERY stable with those, folding was a problem. My final technique was well jigged pushrod in my c-frame and my 3x gun with the pressure up 10-20 psi from normal. That first hit or three really made the difference. I had more problems with the aileron pushrods. I made a few extra before I found my setup.
