Thanks, I see how the plate can help.

I put in a small plastic rod in until it touched, the measurement was 7mm. I then measured the thickness of the rc xray mount, it is 3mm. My screw is 7mm, so it goes is 4mm. I also do think the thread thickness in the motor is 5mm, based on this I should be good.

Thanks for the info, very helpful!!
