QQ190 RTF camera pod assembly

As I was cruising around the other day I noticed my camera (upgraded version) had become unfocused.  I tried to get it back in focus but couldn’t turn the lens with the front camera support attached. I took off the support and got the camera focused, but now I can’t get the front support back on. I can’t tell if there’s enough space between the lock ring and the lens for the support to fit, or if I’m just not pushing it on hard enough. Either way, there’s not much room for the support to fit.

I looked at a Swift 2 that I have and there’s not enough room for the support if I wanted to switch to it or another camera like it. I am planning on switching to a camera with 16:9 to match my goggles, but I need to know that I can make what I buy fit.

Do you have any tips, or even a link to detailed assembly instructions for the camera pod?  I know I’ve read that we can use other cameras so I’m sure I’m missing something.

Thank you for your time
